Cleaning and Maintenance

General
To ensure the accuracy of the multimeter over an extended period of time, it should be calibrated once a
year.
Apart from occasional cleaning and fuse replacements, the meter requires no servicing.
Information on changing the battery and fuse is provided below.
Regularly check the technical safety of the instrument and measuring lines, e.g.
check for damage to the housing or squeezing etc.

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).
The connected lines must be disconnected from the measuring device and all
measuring 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, slightly
damp 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 (15) 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 com-
partment is opened. The housing no longer has to be opened and disassembled completely.
These measures improve user safety and operational comfort.
