E. Testing Diodes
To avoid harms to you, please do not attempt to input
voltages higher than 60V DC or 30V rms AC.
To avoid damages to the Meter or to the devices under
test, disconnect circuit power and discharge all the
high-voltage capacitors before testing diodes.
Use the diode test to check diodes, transistors, and
other semiconductor devices. The diode test sends a
current through the semicondutor junction, then measure
the voltage drop across the junction. A good silicon
junction drops between 0.5V and 0.8V
To test the diode out of a circuit, set up the Meter as
Figure 3-5 and proceed as follows:

2.
Insert the red test lead into the
black test lead into the COM terminal.
Set the rotary switch to
