Diode/Continuity/Remote test
Diode detecting:
Warning!
To prevent electric shock, please do not detect the diode with voltage carried.
1. Put the banana plug of the black P-wire into the cathode COM socket, and the red one to the anode
socket.
2. Spin the function switch to select the
measuring range.
3. Cross connect to both sides of the tested diode or the PN-junction of the semiconductor. Be notice to the reading
displayed on the meter.
4. Exchange the position of the test pen to reverse its polarity. Be notice to the reading displayed on the meter.
5. The performance of the Diode or PN-junction of the semiconductor can be determined according to below situation:
If one reading displayed a voltage value (approximately 0.2V-0.7V) and the other displayed as “O.L”. It means the diode is
fine.
If both readings displayed as “O.L”, it means the diode break.
If both readings are low or shown as zero, it means the diode short-circuited.
Continuity test:
Warning!
To prevent electric shock, please do not operate a continuity test in a circuit carried with voltage
