Diode Measurement
(see diagram 5)
Diagram 5
1. Turn the rotary switch to the “ ” position for diode measurement.
2. Insert the red test lead into the “ ” terminal and the black test lead into the
“COM” terminal. The red test lead is “+”, the black test lead is “-”.
3. In a circuit, a good diode should still produce a forward voltage drop reading
of 500~800mV. However, a reverse voltage drop reading can vary depending
on the resistance of other pathways between the probe tips.
