Use the diode test to check diodes, transistors, and silicon-controlled rectifiers (SCR), and other semiconductor devices. The
test sends a current through a semiconductor junction, and then measures the junction’s voltage drop. A typical junction drops
0.5 V to 0.8 V.
To test a diode, proceed as follows:
1.
Set the rotary switch to position, and press blue button ( ) to select diodes testing, and the symbol “ ”will be shown
on the left part of the screen.
2. Insert the black lead into “
