CAUTION: To avoid the meter or measured
equipment from being damaged, cut off all
power supply of measured circuits and
discharge all high voltage capacitors
before measuring diode.
□ Turn the rotary switch to the
position (1).
□ Press the FUNC key (2) and select the
measuring range.
□ Separately connect the black and read
test leads to the negative pole and
positive pole of the measured diode.
□ The meter displays the forward bias value
of the measured diode. If the poles of the
test leads are connected inversely, the
meter will display “OL”.
For on-line measuring diode, the
meter displays the forward voltage
drop at forward measurement; the
reverse
measurement depends on
the values of other elements
connected in parallel at both ends
of diode.
Measuring continuity

CAUTION: To avoid the meter or measured
equipment from being damaged, cut off all
power supply of measured circuits and
discharge all high voltage capacitors before
continuity measurement.
□ Turn the rotary switch to the
position (1).
□ Press the FUNC key (2) and select the
measuring range.
□ Separately connect the two ends of the
test leads to the end ends of the
measured part and circuit.
□ The meter displays the approximate
resistance value between measured
points. Here if the resistance value
between measured points is less than
50±20 Ω, the buzzer will make a sound.
