Use Of The Multimeter; Basic Settings - Conrad 4660 M Mode D'emploi

4. Use of the Multimeter

4.1 Inserting the Battery - Battery Exchange
To guarantee precise measurement, insert a standard 9 V battery. If the
battery symbol appears in the display, it is time to change the battery.
Proceed as follows:
• disconnect your measuring unit from the measuring circuit
• disconnect the test-leads from the measuring unit and turn off the
power.
• remove with a crosspoint screw driver the fastening screw to open the
battery compartment.
• now lift the cover carefully.
• separate the old battery from the battery snap and fasten a new one
of the same type.
• after the battery has been changed reinsert the battery into the batte-
ry case and close it carefully
• secure it with the screw.
• be careful that the battery leads (red/black) are not pinched between
the housing and the cover.
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 (collec-
ting points) or in a safe manner that complies with all applicable laws.

4.2 Connection of Connecting Cables
When measuring, always use only the connecting cables, or adapter/
cables supplied, which are an optional item of DMM and thus specially
adapted to it. Before any connection, make sure that the connectors, or
measurement clips, are in good condition, and that the insulation is free
of damage.
The connecting cables supplied are approved for voltages up to 1000 V
max. Your measuring device, M-4660M has been designed for voltages
up to 1000 VDC/750 VACrms max. Please take special care with voltages
higher than 25 V AC/35 V DC.
Attention!
To avoid the risk of electrical shock, instrument damage and/or equip-
ment damage, input limits must not be exceeded.
