Warning Description Resolution
TEMP CAL TO
DO
The Sensor Days value for the temperature
sensor is greater than the Cal Reminder value.
Calibrate the temperature.
CL MAINT
RECD
Chlorine sensor maintenance is recommended.
The slope is 30 to 45% of default or the slope is
250 to 300% of default.
The default slope is 100 mV/ppm (100%).
Do sensor maintenance and
then repeat the calibration, or
replace the sensor.
CL MAINT
RECD
Chlorine sensor maintenance is recommended.
The offset is -50 mV to 45 mV or the offset is
45 mV to 50 mV.
Do sensor maintenance and
then repeat the calibration, or
replace the sensor.
PH MAINT
RECD
pH sensor maintenance is recommended.
The slope is outside of the -50 to -61 mV/pH
range.
Clean the pH sensor, then
repeat the calibration with a
fresh buffer or sample, or
replace the sensor.
PH MAINT
RECD
pH sensor maintenance is recommended.
The offset is outside of ±45 mV but within
±60 mV.
Clean the sensor and then
repeat the calibration, or
replace the sensor.
PH MAINT
RECD
pH sensor maintenance is recommended.
The offset is outside of ±45 mV but within
±60 mV.
Clean the sensor and replace
the salt bridge and standard
cell solution and then repeat
the calibration, or replace the
sensor.
T MAINT RECD The temperature offset is outside of ±3 °C but
within ±5 °C.
Calibrate the temperature.
