Use a clean, lint-free, antistatic and slightly damp cloth to clean the device and display. Allow the
device to dry completely before using it for the next measuring task.
c) Opening the measuring device
For reasons of safety, it is only possible to replace the fuse and battery when all test leads have been
removed from the measuring device. The battery and fuse compartment cannot be opened when test
leads are plugged in.
In addition, when the housing is opened all measuring sockets are mechanically locked in order to
prevent the later insertion of the test leads. The locking will be automatically removed when the battery
and fuse compartment is again closed.
The housing is designed so that when the battery and fuse compartment is open only the battery
and fuses can be accessed. The housing does not have to be opened completely or taken apart any
longer. These measures increase the user safety and user-friendliness.
Proceed as follows to open:
1. Remove all test leads from the measuring device and switch
it off.
2. Loosen and remove the battery compartment screw (15) on
the back.
3. Fold out the positioning bracket (13). Pull the battery and
fuse compartment lid downwards from the measuring device
(Fig. 11).
4. The fuses and battery compartment are now accessible.
5. Close the housing in the reverse order and screw closed the
battery and fuse compartment.
6. The measuring device is again ready for use.
