Never exceed the limit value for protection. This limit value is listed
separately in the specifications for each range of measurement.
Do not touch unused terminals when the meter is linked to a circuit
which is being tested.
Never use the meter with CAT 2 installations when measuring
voltages that might exceed the safety margin of 600V above earth
ground.
Set the range selector at its highest position if the intensity of the
charge to be measured is unknown beforehand.
Disconnect the test leads from the tested circuit before rotating the
range selector in order to change functions.
When carrying out measurements on a TV set or switching power
circuits, always remember that the meter may be damaged by any
high amplitude voltage pulses at test points.
Always be careful when working with voltages above 60Vdc or 30Vac
rms. Keep your fingers behind the probe barriers at all times during
measurement.
Never perform resistance, diode or continuity measurements on live
circuits. Make sure all capacitors in the circuit are depleted.

General Description

The DVM851 is a battery-operated, hand-held 3 ½ digital multi-meter
for measuring DC and AC voltages, DC current and resistance. It also
offers the possibility of executing continuity tests and of testing diodes
and transistors. The back light is optional.
Refer to the illustration on page 2 of this manual:
