Attention!
Never use the measuring unit before the cover has been closed comple-
tely, to avoid an electrical shock!
Never leave empty batteries in the measuring unit, as even corrosion-
free batteries might leak and chemicals could be released, which are
detrimental to your health and disturb the battery compartment.
Please remember batteries - due to their heavy metal content - are no
ordinary refuse. They must be disposed of in special containers or in a
safe manner that complies with all applicable laws.
4.2 Connection of the Measuring Cables
For measurement use only the type of test-leads which are supplied with
your measuring unit. Only these are admissible. Ensure the connection
plugs and test probes are in good condition before usage, pay attention
that the insulation is undamaged.
These test-leads are rated for max. 1200 V. The maximum rating of the
multimeter M-3860M is 1000 VDC max or 750 VACrms. Use special cauti-
on when working with voltage above 25 V AC and above 35 V DC.
Attention!
To avoid the risk of electrical shock, instrument damage and/or equip-
ment damage, input limits must not be exceeded.
4.3 Using the Stand
Your meter has a stand on the rear side for bench use which can be
opend away from the meter. You can prop the unit for improvement of
reading.
