Cleaning
Always observe the following safety instructions before cleaning the device:
ƽ
Live components may be exposed if covers are opened or parts are removed (unless
this can be done without tools).
The connected lines must be disconnected from the measuring device and all mea-
suring objects prior to cleaning or repairing the device. Switch the DMM off.
Do not use any carbon-containing cleaning agents or petrol, alcohol or the like to clean the product. These
could corrode the surface of the meter. 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.
When cleaning the device or the display and the measuring lines, use a clean, lint-free, antistatic, cloth.
Allow the product to dry completely before you use it again to conduct measurements.
Opening Meter
For safety reasons, fuses and batteries may only be changed after all measuring lines were removed
from the measuring device. The battery and fuse compartment (17) cannot be opened when the measu-
ring line is inserted.
Also, the measuring jacks are mechanically locked when it is opened so that no measuring lines can be
inserted while the housing is opened. The locks is automatically removed when the battery and fuse
compartment is closed again.
The housing design only permits access to the battery and fuses even when
the battery and fuse compartment is opened.
These measures improve user safety and operational comfort.
Proceed as follows to open it:
- Disconnect all measuring leads from the meter and switch it off.
- Unscrew and remove the rear battery compartment screw (13).
- Slide the battery and fuse compartment lid (16) downwards off of the mea-
suring device with the mounting bracket folded shut.
- The fuses and the battery compartment can be accessed now.
- Close the housing again in the reverse order and screw the battery and
fuse compartment closed.
- The meter is ready for use once again.
