Maintenance
When using the instrument in compliance with the instruction manual, no special main-
tenance is required. Should operational problems occur during daily use, our consult-
ing service (phone +49 77-22 959-0) will be at your disposal. If functional errors occur

Cleaning
If the instrument is dirty after daily usage, it is advised to clean it by using a humid cloth
and a mild household detergent.
Prior to cleaning, ensure that instrument is switched off and disconnected from
external voltage supply and any other instruments connected (such as UUT, control
instruments, etc.).
Never use acid detergents or dissolvants for cleaning.
Calibration interval
The instrument has to be periodically calibrated by our service department in order to
ensure the specified accurcy of measurement results. We recommend a calibration
interval of two year years.
Battery replacement
Prior to battery replacement, disconnect the instrument from any connected test
leads. Only use batteries as described in the technical data section!
• Switch off instrument. Disconnect test leads.
• Loosen the screws of the battery cover on the instrument rear. Lift the battery
cover.
• Remove discharged batteries.
• Insert new batteries 1.5 V IEC LR03.
• Replace the battery cover and retighten the screws.
Please consider your environment when you dispose of your one-way batteries or
accumulators. They belong in a rubbish dump for hazardous waste. In most cases, the
batteries can be returned to their point of sale.
Please, comply with the respective valid regulation regarding the return, recycling and
disposal of used batteries and accumulators.
If an instrument is not used over an extended time period, the accumulators or batter-
ies must be removed. Should the instrument be contaminated by leaking battery cells,
the instrument has to be returned for cleaning and inspection to the factory.
Fuse replacement
Prior to fuse replacement, ensure that multimeter is disconnected from external
voltage supply and the other connected instruments (such as UUT, control
instruments, etc.)
Only use fuses as described in the technical data section! Using auxiliary fuses,
in particular short-circuiting fuse holders is prohibited and can cause instrument
destruction or serious bodily injury of operator.
• Switch off the instrument. Disconnect test leads.
• Loosen the screws on the instrument rear.
• Lift the case cover.
• Remove the defect fuse.
• Insert new fuse.
• Replace the case cover and retighten the screws.
