3.2.4 Diode test
To avoid the meter or the measured equipment from damage,
do not attempt a diode test unless the operator has already
cut off all power sources for the circuit to be measured and
fully discharged all high-voltage capacitors.
Diode test outside the circuit:
1. Turn the rotary switch to the position .
2. Connect the test leads in black and in red to COM input socket and
V/ input socket respectively.
3. Connect the test leads in black and in red to the positive and negative
poles of the diode to be tested respectively.
4. The meter displays the forward bias value of the diode to be tested. If
the polarity of the test lead is reversed, the meter will display "OL". A
normal diode still produces a forward voltage drop of 0.5V to 0.8V; the
reverse bias voltage reading depend on the variation in electric
resistance of other channels between two pen-shaped meters.
3.2.5 Beep continuity test
To avoid the meter or the measured equipment from damage,
do not attempt a beep continuity test unless the operator has
already cut off all power sources for the circuit to be measured
and fully discharged all high-voltage capacitors.
Steps for a continuity test:
1. Turn the rotary switch to the position .
2. Press the "Select" key to select
measure.
3. Connect the test lead in black and test lead in red to COM input socket
and V/ input socket respectively.
4. Use another two ends of the test lead to measure the resistance of the
circuit to be measured. If the me
asured distance is no more than 30Ω,
the sensor LED will be on and the beeper will sound continuously.
