Do not use any carbonaceous cleaning agents or
petrol, alcohol or similar for cleaning. They may
attack the surface of the unit. Additionally, the fu-
mes are explosive and damaging to health. Do not
use any sharp-edged tools, screwdrivers, metal
brushes or similar for cleaning..

Never operate the measuring instrument in an ope-
ned condition. Danger to life!
Do not leave used batteries in the measuring instru-
ment, because even leak-proof batteries can corro-
de and thereby release chemicals, which are both
damaging to health and can destroy the battery
compartment.
Disposal of used batteries/accumulators
As an end user you are committed by law (battery sta-
tutory regulation) to giving back all the used batteries
and accumulators. It is not permitted to throw them in-
to the domestic dustbin. Batteries/accumulators that
contain harmful substances are marked with the oppo-
site symbols. These symbols indicate that it is not per-
mitted to throw the batteries/accumulators into the
domestic dustbin. The symbols for the decisive heavy
metal are: Cd = cadmium, Hg = mercury, Pb = lead.
Give back your used batteries/accumulators at the
collecting boxes provided by your municipality, at our
branches or at the shops that sell batteries/accumulators.
You meet the statutory requirements and make your
contribution to the environmental protection.
b) Changing fuses
Make sure that only fuses of the given types and
nominal current ratings are used as replacements.
The use of repaired fuses or the bridging of fuse
holders is not permitted.
To change the mA current range fuse, disconnect the measuring in-
strument from the circuit being measured and switch it off. Remove
all connected leads and test probes. Take a suitable crosspoint
screwdriver and carefully open the instrument case, as described
