2 RS232 port or external power supply 5 EC sensor

3 Battery cap

The ORBISPHERE 3655 portable analyzer is configured to make high-sensitivity dissolved hydrogen

or oxygen concentration measurements, with Electrochemical (EC) Sensors, for the power industry.

Locate the instrument convenient to the sample being analyzed and to the PC if one is being used. A

6-pin LEMO connector for RS-232 serial output to a PC, or an optional external power source is

located on the right side (as illustrated in Figure 1).

3.1 Sensor installation

The sensor has a threaded collar and calibration cap, and a screw-on protection cap to prevent

disturbances to the membrane. A plastic screw-on base at its rear provides a stand for servicing, and

protects the sensor's screw-on 10-pin LEMO connection.

The sensor connects to the instrument base through a 10-pin LEMO connector. A locking nut holds

the sensor in place. Generally, the sensor is shipped already installed in the instrument.

Shipping conditions can have adverse effects on the sensor, thus you should perform a sensor

service as described in the accompanying Sensor Manual before trying to make measurements.

3.2 Flow chamber installation

The model 32007D flow chamber draws the liquid sample past the sensor. It attaches to the sensor

with a threaded collar and is then sealed to the sensor with two O-rings. The flow chamber centrally

located inlet and eccentrically located outlet use either ¼-inch or 6-mm diameter transparent plastic

tubing. Connect by compression fittings to the sample source and to the drain, respectively.

3.3 WinLog97 PC program installation

Install the WinLog97 program onto the PC by inserting the accompanying CD into your PC and

running the SetUp program. Simply follow the on-screen instructions. When finished, a new Windows

Program Group labeled Orbisphere is created containing the software and help files.

3.4 Connections

3.4.1 Batteries

The instrument is designed to work on battery power.

If battery power should drop, a LO BAT warning appears in the instrument LCD's top-left corner, and

they should be replaced.

3.4.2 External power (optional)

The instrument is usually powered by the batteries supplied. You can, however, power it from an

external +5VDC source (as supplied by an electronics supply store). Connect the 2-wire output from

this source, using a model 28083 male 6-pin LEMO plug, to the RS-232 connector on the right side

all nine pins accessible. Some 25-to-9 pin adapters are supplied for specific use, such as a mouse, and these may

have only certain pins available.

It is not necessary to keep the PC connected to the instrument during measurement. This connection

is required for downloading stored measurements, real-time monitoring, reviewing and changing

configuration parameters and testing the instrument from the PC.

3.5 Installation checklist

3.5.1 Instrument clock setting

If you use the instrument to store measurements for downloading to a PC, you should verify the date

and time settings of the instrument's internal clock, as described in Clock settings on page 17.

3.5.2 Electrochemical sensor

Shipping conditions can have adverse effects on the sensor, thus you should perform a sensor

service as described in the accompanying Sensor Manual before trying to make measurements.

3.5.3 Flow chamber

The model 32007D flow chamber's inlet and outlet should be free of any obstructions.

3.6 Storage when not used

At the end of the workday, run clean water through the flow chamber to prevent passageways from

clogging. You may wish to repeat preconditioning (see Preconditioning sensors on page 9) prior

to the next use.

If you do not expect not to use your sensor for more than a few months, you should clean the sensor

as instructed in the Sensor Manual and then store it dry, without electrolyte, and with the calibration

cap in place for protection.

Section 4 User interface

4.1 Keypad and function keys

The front panel of the instrument has a three-digit liquid crystal display (LCD). The LCD includes a

right-side marker to distinguish between gas concentration and temperature display. This marker

also indicates the measurement display units (ppm, ppb, etc.) depending on the instrument model.

To the LCD's right is a label showing the measurement units configured at the factory for your

application.

In addition to the controls indicated on the front panel, there is also a pressure relief valve switch on

top of the instrument (as indicated in Figure 1 on page 5) to enable atmospheric pressure equilibrium

for sensor calibration. The panel keyboard has the following push-button controls:

English

7

Power switch. This turns instrument power on or off. The instrument starts in measurement mode

Places the instrument in measurement mode

Calibrates the analyzer against a reference sample. This button can be locked out from the

WinLog97 PC program

Stores a measurement value into memory

Backlights the LCD for approximately three minutes

Toggles between gas concentration and temperature measurement displays in measurement

mode, increases or decreases the storage number during storage or memory view, or sets a

calibration value during calibration

To start the analyzer, press the keyboard POWER switch (located bottom left of the keyboard). When

you turn power on, the instrument displays its model number briefly, and then starts in measurement

mode. You can access other instrument functions by pushing one of these keys while turning power

on:

Sensor calibration on page 15

Start automatic data acquisition - see Automatic data acquisition on page 9

Start memory storage view - see Viewing stored measurements on page 10

Display program identification information

4.2 Taking measurements

Once the system is calibrated, you should be able to begin taking measurements. Connect the top-

mounted inlet to accept your sample, typically this is accomplished by connection to a sampling

valve.

Minimum flow rates, measurement limits and response times for the various available membranes

are given in the accompanying Sensor Manual.

8

English

To switch between gas measurement and temperature measurement, press the Up/Down Arrow

buttons.

To backlight the LCD for approximately three minutes, press the Backlight button.

4.3 Preconditioning sensors

You can expect a more rapid and accurate first result if you precondition the sensor before you take

readings. You may want to precondition prior to each series of measurements, depending on

frequency of use.

To precondition, connect the flow chamber to a convenient sampling source at or below expected O

2

or H

2

levels. If measurements take place in carbonated samples, precondition with carbonated water.

Open the sampling valve on the flow chamber, just enough for a trickle. Then, switch on the

instrument and watch the LCD. You will see the values drop.

Typically for oxygen, if you are measuring in the 0.1 ppm range, then only a short time is required for

the display to fall to this level, whereas ppb level measurements may require the sensor to remain

exposed to the sample for half an hour or more. You will establish your own requirement with

experience.

Once the LCD displays the expected level of O

2

or H

2

, close off the sample. The sensor is now

preconditioned and ready to use.

4.4 Storing measurements in the instrument

The instrument will store up to 500 gas measurement values, labeled by numbers 0 through 499,

along with the current date and time of each measurement. You have the choice of acquiring this

information manually or automatically, as described below.

Before storing measurements, you should verify the date and time settings of the instrument's

internal clock, as described in Clock settings on page 17.

4.4.1 Automatic data acquisition

Note: When the instrument is used to automatically store measurement data, all buttons except the POWER key

are disabled. If enough time elapses to store all 500 values, the instrument will return to normal measurement mode

and the buttons re-enabled.

Before starting automatic measurement storage, first select the sampling rate desired using the

Sampling Rate menu of the WinLog97 program (see Automatic data acquisition - setting sampling

intervals on page 13).

1. Switch the instrument OFF (by pressing the POWER key).

2. Then hold down the STO button while switching the instrument back ON. The LCD displays the

message Sto for about one second.

3. Normal gas concentration measurements are displayed for about two minutes.

4. After two minutes the instrument displays the sample number (starting at 000), then the gas

concentration measurement value followed by [- - -] to indicate the measurement is being stored.

5. This storage sequence repeats automatically, at the rate specified by the WinLog97 program

Sampling Rate menu. Values are stored sequentially in sample numbers 000 through 499.

Note: If you have not cleared previously stored values, the storage sequence automatically overwrites the older

values, as they are stored.

6. To end automatic storage, switch the instrument OFF (by pressing the POWER key) while it is in

normal measurement mode and not while it is in the process of automatically storing data.

7. Switching ON again without holding down the STO button returns the instrument to measurement

mode.

Note: If you accidentally interrupt the automatic data storage by switching off the instrument while it is in the

process of storing a value, and you then attempt to download the stored values by the WinLog97 program, you

will get a Windows Checksum Error message, and you will not be able to view the measurement data. If this

happens, then go back to the instrument and manually log one more value (as described in Manual data

acquisition on page 10). You can then download your original set of values to your PC.

English

9

4.4.2 Manual data acquisition

Note: You cannot store measurement data manually if the instrument has already been set up to store the data

automatically.

1. For the first measurement you wish to store, press the STO button once to display a sample

number. The default sample number is 000 (for first time access), or the last used memory

position where data was stored, incremented by a value of 1.

2. You can increase or decrease this number by pressing the Up/Down Arrow buttons within three

seconds.

3. Should you decide at this point, not to store this particular measurement, just wait five seconds

and the display returns to measurement mode. You may also exit this routine by pressing the

MEAS button.

4. Press STO a second time, within five seconds of the first. The instrument then displays a brief

clearing [- - -] message, followed by the gas concentration measurement value for about three

seconds

5. The [- - -] message is displayed as this measurement value is stored

6. Repeat the above steps to store additional measurements.

If you stored the first value as sample 001, the instrument automatically increases the next

storage location, and labels it sample 002. You can increase or decrease this number by pressing

the Up/Down Arrow buttons. If you label a sample number the same as a previously stored

measurement value, the new measurement value overwrites the previously stored value.

4.4.3 Viewing stored measurements

1. Switch the instrument OFF (by pressing the POWER key).

2. Hold down the Up Arrow button while switching the instrument back ON. The LCD displays a

sample location number.

3. Scroll through the numbered sample locations of all the stored values using the Up Arrow and

Down Arrow buttons.

4. To view the actual gas concentration measurement value at a particular sample number, press

the STO button. The LCD now displays the stored value for that sample number.

5. Press STO a second time to return to the next numbered location display, to continue scrolling or

view another stored value.

6. To return to the measurement mode, switch the instrument OFF and then back ON again without

holding down any additional buttons.

4.5 Storing and accessing measurements from the PC

If you have made measurements and stored them in the instrument, you should be ready to bring

them into the WinLog97 program for viewing, copying, saving and printing. See also Options setup

on page 12 for additional information on the WinLog97 program.

4.5.1 Downloading stored values

To download the stored results from the instrument to the PC, choose the DownLoad data command

from the Logger menu.

The DownLoad window presents a display of the stored measurements from the instrument. The

window displays five columns of data:

• Sample (sequence number of the sample)

• Gas (concentration of the measured gas)

• Date (date of the measurement)

• Time (time of the measurement)

• Sample Description

The descriptions can be modified for your applications using the procedures described below.

10

English

4.5.2 Altering the sampling point descriptions

For help in identifying the locations of various sampling points that are stored by the instrument, you

may choose the Sampling Point Description command from the Logger menu to bring up the

dialog box.

The measurement values to be placed in positions 0 through 499 (identified as Text 0, Text 1... etc.)

can be described however you wish. Double-click on a particular position (or click Modify), then type

a description in the box. Choose OK when finished entering a description.

When you Close this box, your modifications will be saved, and will appear in the Sample

Description column for the next downloaded list. These descriptions can be modified again later as

your requirements change.

4.5.3 Copying values

To copy the results to the Windows Clipboard, so that the data can be pasted into a spreadsheet,

word processor or other Windows program that accepts tabular text information, choose the

Clipboard command from the Export menu.

4.5.4 Saving values

To save this list of measurements as a text (.txt) file, capable of being recalled by the

WinLog97 program or imported as a file into other Windows programs, choose the Save As

command from the File menu. A dialog box appears, with a space to fill in with an eight-letter name.

(The program automatically attaches a .txt suffix to these files.) If you have saved previous files, a

grayed-out list of these names appears as well. Typical to Windows programs, Directories and

Drives boxes can be used to locate other places to save. You may also type the drive and directory

yourself when saving the file.

4.5.5 Printing values

To place this list of measurements into a tabular format and send it to the Windows printer, choose

the Print command from the File menu. The program asks you to enter Title and Author

information. Note that the Date is fixed by your operating system. The resulting printed list will

include this information on each page.

4.5.6 Clearing stored values

To clear all the values stored in the instrument via the WinLog97 program, choose the Clear Data

command from the Logger menu. Since this action will clear the storage memory of the instrument, a

warning appears first. Choose OK to bring up the next dialog box to confirm the clear action. Choose

Clear to start the memory clear operation. A message, Reset should be completed appears in this

box when the task is finished.

Note: You can accomplish the same thing passively, by simply allowing the analyzer to overwrite a set of stored

values with new ones.

4.6 Monitoring measurements in real-time

You may wish to analyze a particular sampling point via the WinLog97 program's Monitoring menu.

To use this Monitoring chart, the instrument must be connected to your PC. Choose Monitoring from

the WinLog97 menu to bring up a chart display.

The Monitoring chart shows the gas concentration (in blue), temperature (in red), and pressure (in

green) as the sample is being measured by the instrument. The chart is updated directly from

instrument measurements, at a rate determined by the time scale set in the TIMEBASE box at the

lower right corner of the chart.

Click the TIMEBASE up/down pointers to change the time scale of the divisions of the chart. Each

division mark along the baseline (1, 2, ...10) can be made to represent from 30 seconds to 2½ hours,

providing from 5 minutes to 25 hours of continuously displayed samples. The chart updating rate is

determined by the time scale selected.

Timebase Updating rate* Maximum samples

*This chart's updating rate is independent from the acquisition rate (see Automatic data acquisition - setting

sampling intervals on page 13).

Click on the Continuous box, in the lower right corner, to enable or disable continuous charting.

When this box is checked, the chart scrolls continuously after reaching the 10 division, and the oldest

samples are lost off the left of the chart. When Continuous is not checked, the chart stops displaying

new results after reaching the 10 division, and all subsequent measurements are lost.

Click the up/down pointers for each measurement variable (GAS, TEMPERATURE and

PRESSURE) at the right of the chart to change the scaling of that value on the chart. The display of

each measurement variable may be turned on or off by choosing the appropriate On or Off switch at

the right of the chart.

If your measurements do not chart properly, try using a higher or lower value scale or time base than

the one displayed. Adjust these scale factors before starting the monitoring operation. A running

display of latest sample Gas, Temperature and Pressure is also shown in the bottom-right corner of

the chart.

Use the buttons at the bottom of the chart to control real-time monitoring. Choose Go to clear the

chart and start real-time monitoring display, Stop to stop real-time monitoring and Copy to copy the

data from the chart as text information to the Windows Clipboard. This information can be pasted

from the clipboard into any Windows application, such as a spreadsheet or word processor. Finally,

choose Close to close the Monitoring window.

Section 5 Options setup

The WinLog97 program is an integral part of the analyzer. Running under Microsoft Windows

®

, it

permits you to list and analyze up to 500 stored measurement values. The program also includes a

special monitoring feature, which lets your computer act as a chart recorder, and enables a hardware

test to ensure that the system is in good working order.

5.1 Main menu basics

When you start the program, it displays the

Main Menu, which automatically maximizes

on opening and appears as follows:

•

File serves typical Windows file management needs.

• The Logger menu lets you download measurement values from the instrument, make

modifications to the sample list that can be used to identify sampling point locations, or clear the

instrument's stored values.

• Export places your information into the Windows Clipboard, so that it can be pasted directly into

other Windows programs. This is especially useful when working with spreadsheet programs, but

the information can be pasted into word processing programs as well.

• The Monitoring menu creates a running chart of real-time measurements (see Monitoring

measurements in real-time on page 11). These can also be saved to the Windows Clipboard.

• The Configuration menu lets you see how your system has been configured for your application.

You may change the PC's COM port, the sensor membrane, automatic data acquisition rate, or the

12

English

sensor calibration mode. You may also lock out the instrument's CAL button, or for calibration

using a span gas, you may enter the span gas percentage.

• The Troubleshooting menu includes a series of tests, permits the setting of the clock, and

enables a barometric pressure calibration routine.

• The Help menu gives access to the Help file and allows the identification of the

WinLog97 program.

5.2 Instrument - PC connection

For the hardware connection of the instrument to a PC, see Instrument - PC connection on page 6.

The Configuration, Serial port menu lets you choose one of four serial communication ports.

Usually, COM1 is used to connect to a mouse, so try COM2 first. You may find that a separate SetUp

program supplied with your PC is necessary to activate this port. Click on OK to activate the selected

port. If the port you have selected here is adequate, the WinLog97 program will return to the main

menu. Otherwise, you will see an RS232 ERRORS message advising you to select another port.

5.3 Reviewing instrument configuration

To review if the analyzer is set up as expected, choose the Configuration, Configuration view

command.

You may change a number of these settings using the WinLog97 program. The modifiable settings,

and information relating to these settings are listed in the next section, Configuring the instrument.

However, should you see any unexpected items listed on your screen which you are unable to

correct, please contact your Hach Lange representative.

5.4 Configuring the instrument

The analyzer can be readily configured for your application using the following commands in the

Configuration menu. The instrument must be connected to your PC in order to change its

configuration.

5.4.1 Automatic data acquisition - setting sampling intervals

The instrument can perform as a standalone data acquisition device, automatically recording gas

measurements with the date and time, and storing up to 500 of these values. Choosing the

WinLog97 program's Configuration, Sampling Rate menu lets you select time intervals (acquisition

rate) for this storage capability.

Use the slide bar to view and select a sampling rate, from 15 seconds to 1 hour. The selected rate is

shown in the Acquisition rate window. Click OK to save this rate. Once your choice is made, the

instrument can be used independently of the WinLog97 program for data acquisition, as described in

Automatic data acquisition on page 9.

Note: The Acquisition rate set via this menu is independent from the monitoring chart updating rate described in

Monitoring measurements in real-time on page 11. The sampling rate menu applies only to automatic data

acquisition, while the chart updating rate is used only for displaying real-time results via the monitoring chart.

5.4.2 Membrane selection

You may find it necessary to use a different type of membrane for different applications. Naturally,

with any membrane change, you will need to re-calibrate (see Sensor calibration on page 15). You

should also consider the changes in required flow rates and response times, which are specified in

the accompanying Sensor Manual.

To re-configure the analyzer, choose Configuration, Membrane to bring up the box which reveals

the membrane models available. Choose OK when the desired membrane is selected.

5.4.3 Selecting type of calibration

5.4.3.1 Select from the PC

You can use the Configuration, Calibration mode command to select how the sensor is to be

calibrated.

Note: Only the calibration modes applicable to your sensor can be selected. Others will be grayed out.

English

13

Choose In Air to allow calibration of the sensor in air (only applicable to Oxygen sensors). Choose In

Line to calibrate the sensor directly in the sampling line, in a sample of known gas content or select

In a Span Gas to calibrate in a source of gas of known oxygen or hydrogen concentration. Choose

OK when the desired mode is selected.

5.4.3.2 Select from the instrument

1. Switch the instrument power OFF

2. Switch the instrument on by holding down the CAL button and then pressing the POWER button

while still pressing the CAL button

3. The instrument display will show either SPA for span gas calibration, LI for in line calibration, or

Air for in air calibration

4. Use the Up/Down Arrow buttons to change the mode to your choice

5. Press the STO button to set the selected mode. The instrument displays Sto for a few seconds,

then returns to measurement mode

5.4.4 Locking out the instrument's CAL button

You can use the Configuration, Calibration Key Status menu to prevent an accidental sensor re-

calibration from the instrument keyboard.

Choose Disabled to lock out the keyboard CAL button. To unlock this capability, choose Enabled.

Choose OK when the desired mode is selected.

5.4.5 Sensor calibration range checking

When calibration is performed for In Air and In a Span Gas calibration modes, the sensor

measurement current is compared to an ideal current for the selected membrane to determine

whether or not to complete the calibration. You can use the Configuration, Calibration Range

Checking menu to enable or disable sensor calibration range checking in the instrument.

Choose Disabled to calibrate without checking the value of the measurement current, within a range

of 0% to 999% of the ideal current.

When set to Enabled, at calibration the measurement current should be between 25% and 175% of

the ideal current; if the value is outside of these limits, the calibration fails and Err is displayed on the

instrument LCD. Choose OK when the desired mode is selected.

Note: It is recommended to leave range checking enabled. In special measurement situations it may be necessary

to disable range checking. However, contact a Hach Lange representative for further details before disabling this

feature.

5.4.6 Entering a span gas value

When calibrating the sensor in a span gas, use the Configuration, Span Gas menu to enter the

concentration of the gas to be measured in the span gas. Enter the percentage of measurement gas

in the span gas (e.g. 10.00%), then choose OK.

Section 6 Calibration

6.1 Pressure calibration

Since the instrument is sealed against moisture, you must open the barometric pressure sensor relief

valve switch on top of the instrument (see Figure 1 on page 5 for actual location) to permit the

instrument to achieve atmospheric pressure equilibrium, and take an accurate barometric pressure

reading.

This must be done with every calibration. To open the relief valve, depress and hold down the

pressure sensor relief valve switch for five seconds, then release.

If you have access to an accurate barometer, you may wish to calibrate the instrument's internal

barometric pressure sensor. This is done using the PC WinLog97 program. Choose

Troubleshooting, Pressure Calibration and an informational message will appear to warn you that

the instrument’s current pressure calibration will be lost.

14

English

Choose OK to continue. The calibration procedure then displays a Pressure Calibration dialog box.

The Measured Pressure value shows the current instrument pressure reading.

Note: Since the instrument is sealed against moisture, you must open the barometric pressure sensor relief valve

switch (location depicted in Figure 1 on page 5) to permit the instrument to achieve atmospheric pressure

equilibrium, and take an accurate barometric pressure reading.

Enter the current atmospheric pressure, in mbars, in the Calibration Pressure entry box. Choose

Calibrate to direct the instrument to read and display the Measured Pressure using this calibration

value. Choose Quit when you are satisfied with the pressure calibration to return to normal

operation.

6.2 Sensor calibration

When delivered, the sensor is pre-calibrated. However, it should be re-calibrated on site, when being

used for the first time, and always after a membrane change. If you have just replaced the

membrane, allow at least half an hour for the membrane to settle before attempting to calibrate.

If you want to verify the accuracy of the calibration, place the analyzer back in measurement mode

and compare your displayed gas concentration against the value in the appropriate tables found in

the accompanying Calibration Tables booklet.

Your calibration is stored internally and is valid for the life of the sensor's membrane, thus it is not

necessary to repeat the calibration procedure until after the next membrane change.

The sensor can be calibrated either by using a span gas, directly in line in a liquid sample, or in air.

The mode of calibration may be selected using the WinLog97 program or directly from the instrument

(see Selecting type of calibration on page 13 for more details).

6.2.1 Calibration in span gas

The span gas calibration procedure may be used if you have a supply of gas with a known

concentration in % units (use O

2

for oxygen sensors or H

2

for hydrogen sensors). To perform this

type of calibration, the instrument must be set for calibration In a Span Gas. The WinLog97 program

also must be used in this procedure.

Switch on the instrument, if necessary, and wait a minute or so for the displayed measurement to

settle. Then expose the sensor to a span gas sample with a known gas concentration. Enter the

percentage of gas in the span gas using the WinLog97 program (see Entering a span gas value

on page 14).

1. Press the CAL button. Remember, this button may have been locked out to prevent an accidental

reset (see Locking out the instrument's CAL button on page 14 for details).

2. A brief clearing [- - -] message appears.

3. Press CAL again within a 3 second period.

4. The percentage of the measured current to the ideal one is displayed.

5. When the reading is stable, press CAL again.

If the new calibration current is within 25% to 175% of the ideal current, the instrument displays

CAL and returns to the measurement mode. Calibration is now complete, the sensor is

calibrated, and you can proceed with your measurements. If the new calibration current is not

within this range, the instrument displays Err and returns to measurement mode. The system will

not calibrate, and it is likely that a sensor service will be required.

6.2.2 Calibration in line

The in line calibration procedure can be used to calibrate the sensor directly in line, against a liquid

sample with a known dissolved gas concentration. To perform this type of calibration, the instrument

must be set for calibration In line. Switch on the instrument, if necessary, and wait a minute or so for

the displayed measurement to settle. Expose the sensor to a liquid sample with a known gas

concentration.

1. Press the CAL button. Remember, this button may have been locked out to prevent an accidental

reset (see Locking out the instrument's CAL button on page 14 for details).

2. A brief clearing [- - -] message appears.

3. Press CAL again within a 3 second period.

4. A measurement will flash on the LCD, showing the gas concentration of the calibration sample.

5. Assuming you know the gas content to be a certain value, you can adjust the displayed value with

the Up/Down Arrow keys.

6. When the reading is adjusted to the known concentration, press CAL again.

7. The instrument displays CAL and returns to the measurement mode.

6.2.3 Calibration in air (oxygen sensors only)

The oxygen sensor can be accurately calibrated in air. To perform this type of calibration, the

instrument must be set for calibration In air.

In order to calibrate the sensor in air, you will need to extract it from its mounting or flow chamber,

and wipe dry the sensor protection grille (if applicable).

Calibration is best achieved using the storage cap that protected the sensor during shipment. Put

several drops of tap water in the cap, shake out the excess, and then attach it to the sensor by

means of its collar. It is best to leave the cap slightly loose, to avoid compressing the air inside. The

cap and sensor should be about the same temperature.

Switch on the instrument, if necessary, and wait a minute or so for the displayed measurement to

settle.

1. Press the CAL button. Remember, this button may have been locked out to prevent an accidental

reset (see Locking out the instrument's CAL button on page 14 for details).

2. A brief clearing [- - -] message appears.

3. Press CAL again within a 3 second period.

4. The percentage of the measured current to the ideal one is displayed.

5. When the reading is stable, press CAL again.

If the new calibration current is within 25% to 175% of the ideal current, the instrument displays

CAL and returns to the measurement mode. Calibration is now complete, the sensor is

calibrated, and you can proceed with your measurements. If the new calibration current is not

within this range, the instrument displays Err and returns to measurement mode. The system will

not calibrate, and it is likely that a sensor service will be required.

6.3 Calibration range checking

When calibrating the sensor in air or in a span gas, as detailed in Sensor calibration on page 15, the

new calibration current should be between 25% to 175% of the ideal current (which is stored in the

instrument's non-volatile memory for each membrane). If not, the instrument displays Err on its LCD

and the system will not calibrate. When the system will not calibrate, it is likely that a sensor service

will be required.

Note: This calibration range checking can be enabled or disabled using the WinLog97 program (see Sensor

calibration range checking on page 14). It is recommended to leave this checking feature enabled. In special

measurement situations it may be necessary to disable range checking. This will allow calibration between 0% to

999% of the ideal current. Contact a Hach Lange representative before disabling this range checking feature.

Section 7 Maintenance

7.1 Instrument batteries

The instrument operates on battery power (two standard C-type cells). If battery power should drop,

a LO BAT warning message appears in the instrument LCD's top-left corner.

To install the batteries, unscrew the battery cap (on the right side of the instrument) with a coin or flat

screwdriver, place the cells lengthwise into the battery compartment (positive end first), and then

replace the cap. Refer to the diagram on the back of the instrument.

Rechargeable nickel-cadmium batteries may be used - expect about 40 hours of autonomy. Alkaline

batteries provide the longest continuous use though mercury-free batteries are available that present

less of a disposal problem.

English

Make sure that a fully charged (or fresh) set is installed before switching on the instrument.

7.2 Sensor

For information on sensor maintenance and servicing, please refer to the accompanying Sensor

Manual.

Section 8 Troubleshooting

If your analyzer is behaving strangely (failing to calibrate, giving inappropriate measurement values,

etc.) and you have attempted to rectify the problem by servicing the sensor, but to no avail, you may

wish to use the Troubleshooting menu of the PC WinLog97 program to make sure that the

instrument is configured correctly for your application, and is in good working order.

The instrument must be connected to your PC and placed in measurement mode to perform these

tests.

8.1 Serial test

Normally, the analyzer will inform you of a disconnected RS-232 (serial) link when appropriate.

However, you can confirm a good connection using the Troubleshooting, Serial Link Test by

echoing a test message via the instrument.

Enter text characters in the Text to be sent box, then click Send. If the serial link is operating

correctly, the exact same text will be displayed back from the instrument in the Echo box. Choose

Cancel to exit from this test box.

8.2 Keyboard test

The Troubleshooting, Keyboard Test will reveal whether all the analyzer buttons are functioning

correctly.

Press any one of the instrument's buttons (except the ON/OFF button) for a full second or more. The

appropriate square on-screen should darken. Choose Cancel to exit from this test box.

8.3 Display test

Choosing Troubleshooting, Display Test lets you perform a one-way communication between

computer and instrument.

Type a number in the Number box (you may also select one of three units positions for the LCD's

rightmost indicator bar as well). Then choose Send. The number and indicator bar placement should

appear on your instrument LCD.

8.4 Clock settings

Choose the Clock settings command to set the date and time in the instrument.

The first screen displays the current date and time as set in the instrument. If this is correct, choose

Ok, else if either date or time must be changed, choose Modify to bring up the next screen. Enter

the current date and time and choose Ok to store the entry into the instrument. All measurements will

be noted with the appropriate date and time when they are downloaded to the WinLog97 program.

8.5 Analog voltages view

The Troubleshooting, Analog Voltage View gives a real-time look at voltages used by the system

to transmit information about sensor current, temperature and pressure. This is useful when trying to

identify an instrument problem with a Hach Lange service representative either on-site or over the

phone.

When performing this test, if the system is over-range, you may receive a message that states, for

example, The current input is saturated. Similar messages will also appear, to warn when

temperature and pressure limits are exceeded.

The voltage limits for normal operation are:

English

17

• Current channel: -1.5 V to +1.5 V

• Temperature channel: +10 mV to +4 V

• Pressure channel: -100 mV to +100 mV

The Range window on the right side of the Current channel voltage indicates one of the four

instrument ranges: 0 (less sensitive) to 3 (most sensitive).

8.6 Measurements view

The Troubleshooting, Measurements View confirms, on your PC monitor, what your instrument

should be displaying on the LCD for gas concentration and sample temperature. Choose Cancel to

exit from this display.
