Model 72-8155: OPERATING MANUAL
Testing Diodes
Use the diode test to check diodes, transistors, and other
semiconductor devices. The diode test sends a current
through the semiconductor junction, and then measures
the voltage drop across the junction. A good silicon junction
drops between 500mV and 800mV.
To test a diode out of a circuit, connect the Meter as follows:
1.
2.
3.
To avoid damage to the Meter or to the devices under
test, disconnect circuit power and discharge all the
high-voltage capacitors before measuring diodes and
continuity.
Insert the red test clip into the
the black test clip into the COM terminal.
Set the rotary switch to
For forward voltage drop readings on any semiconductor
component, place the red test clip on the component’s
anode and place the black test clip on the component’s
cathode.
The display shows the diode forward voltage drop’s
nearest value.
