Battery Replacement / Calibration Interval
13.0 Battery Replacement
Prior to battery replacement, disconnect the in-
strument from the connected measurement
circuits.
If the battery symbol (8) appears in the dis-
play, proceed with battery replacement.
Switch off the instrument via the function witch
(17).
Loosen the screws on the instrument rear.
Lift the battery case cover (by slightly hitting the
instrument in the palm of your hand).
Remove the discharged batteries.
Insert new batteries and ensure there is correct
polarity.
Only use batteries in compliance with the spe-
cifications in the technical data section. ( Type
6LR61 / Block 9V) .
Replace the battery case cover and retighten the
screws.
The instrument is now ready for further measu-
rements.
Never try to disassemble battery cells. Never
throw a battery into a fire as this could lead to
an explosion. Never expose batteries to humi-
dity
Please consider your environment when you dis-
pose of your used batteries. They belong in a rub-
bish dump for hazardous waste. In most cases, the
batteries can be returned to their point of sale.
Please, comply with the appropriate regulations
concerning the return, recycling and disposal of
used batteries and accumulators.
The instrument is not allowed to be used with
an open battery case
If an instrument is not used over an extended
period of time, the accumulators or batteries
must be removed. Should the instrument be
contaminated by leaking battery cells, the in-
strument has to be returned for cleaning and in-
spection to the factory.
14.0 Calibration Interval
The instrument has to be periodically calibrated by
our service department in order to ensure the spe-
cified accuracy of the measurement results. We re-
commend a calibration interval of one year.
