2) Connect the black test lead to "COWterminal and red test lead
ative side. The meter can display diode voltage drops to approximately 2.5 V.A typ-
ical voltage drop is 0.3~0.8 V, and the meter will sound a beep to remind user.
4) Reverse the probes and measure the voltage across the diode again. If the diode is:
5) Repeat step 3 and 4 for other diodes.
A good diode allows current to flow in one direction only. To test a diode, turn the
power off, remove the diode from the circuit, and proceed as follows:
1 ) Set the rotary switch to "
