Disconnect the live test lead (Red) before
disconnecting the common test lead (Black).
Follow all safety procedures for equipment being
tested. Disconnect the input power and discharge
all high voltage capacitors through a protective
impedance before testing in the and functions.
When making a current measurement, turn the
power off before connection the meter in the circuit.
Check the meter fused before measuring current
transformer secondary or motor winding current.
An open fuse may allow high voltage build-up, which
is potentially hazardous.
To take a measurement, use the test lead probes to
make the proper contacts. Remember, insert the meter
in the circuit in parallel for voltage and in series for
current measurements.
WARNING
TO AVOID ELECTRICAL SHOCK OR DAMAGE
TO THE METER, DO NOT APPLY MORE THAN
1000V BETWEEN COMTERMINAL AND EARTH
GROUND.
TO AVOID ELECTRICAL SHOCK, USE CAUTION
WHEN WORKING ABOVE 60V DC OR 30V AC
RMS, SUCH VOLTAGES POSE A SHOCK HAZARD
