Digital laser measure GLM 20
Dimensions 100 x 36 x 23 mm
A) The working range increases depending on how well the laser light is reflected
from the surface of the target (scattered, not reflective) and how bright the laser
point is relative to the ambient light intensity (interior spaces, twilight). In unfa-
vourable conditions, e.g. with extremely bright interior lighting or a poorly reflect-
ing surface, the measuring range may be reduced.
B) In unfavourable conditions, e.g. with extremely bright interior lighting, a poorly re-
flecting surface, or a room temperature that deviates significantly from 25 °C, the
maximum deviation can be up to ± 7 mm at 15 m. In favourable conditions, a devi-
ation influence of ± 0.05 mm/m needs to be taken into account.
C) non-conductive soiling only, whereby occasional temporary conductivity caused
by condensation is expected
The serial number (5) on the type plate is used to clearly identify your measuring tool.
Fitting
Inserting/Changing the Batteries
It is recommended that you use alkaline manganese batteries to operate the
measuring tool.
Push the locking mechanism (4) in the direction of the arrow to open the
battery compartment cover (3) and remove the battery compartment cover.
Insert the batteries. When inserting, pay attention to the correct polarity ac-
cording to the representation on the inside of the battery compartment.
When the battery symbol first appears on the display, measurements can
be made for approx. another 15 minutes. When the battery symbol flashes,
you have to replace the batteries because measurements are no longer pos-
sible.
Always replace all the batteries at the same time. Only use batteries from the
same manufacturer and which have the same capacity.
u Take the batteries out of the measuring tool when you are not using it
for a prolonged period of time. The batteries can corrode and self-dis-
charge during prolonged storage.
