Cleaning
Always observe the following safety instructions before cleaning the device:
Live components may be exposed if covers are opened or parts are removed (unless
this can be done without tools).
All connected cables must be disconnected from the instrument before servicing or
repair work is performed.
Do not use any carbon-containing cleaning agents or petrol, alcohol or the like to clean the product. This
can attack the surface of the multimeter. Furthermore, the fumes are hazardous to your health and
explosive. Moreover, you should not use sharp-edged tools, screwdrivers or metal brushes or similar for
cleaning.
To clean the device, the display or measurement lines, use a clean, dry lint-free anti-static cleaning cloth.
Inserting/changing the batteries
Operation of the measuring instrument requires batteries, which are included in the delivery.
Insert new batteries when commissioning the device for the first time or if it is no longer possible to per-
form a null balancing.
To insert/replace batteries, proceed as follows:
- Remove all measuring leads and turn the multimeter off.
- Remove the rubber holster from the casing.
- Loosen the screws on the back of the casing and carefully pull off the cover.
-
Now place new batteries into the battery compartment. Observe the correct polarity indicated in the
battery compartment.

- Now close the housing carefully again.
Do not leave flat batteries in the device. Even batteries protected against leaking can
corrode and thus release chemicals which may be detrimental to your health or
destroy the battery compartment.
