Battery Replacement
If the battery symbol appears in display (3), the battery has
to be replaced. Please proceed as follows:
1) Disconnect the instrument from the measurement cir-
cuit.
2) Switch off the instrument.
3) Loosen both screws in the casing rear.
4) Carefully open the casing.
5) Replace the old battery with the new one by respecting
the correct polarity! For the battery type, please refer
to the technical data section.
6) Carefully close the casing.
7) Insert the screws and ensure they are tightened.
If the instrument is likely to remain unused for a long
period of time the batteries must be removed. If a bat-
tery should leak inside the housing, return the instru-
ment to our service department for cleaning and chek-
king.
Please think of our environment when getting rid of used
batteries. They should be disposed of in a place suitable
for hazardous waste.
