Diode and Continuity Test

Testing Diodes
Warning
To avoid damages to the Meter or to the devices
under test, disconnect circuit power and discharge
all the high-voltage capacitors before 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 0.5V and 0.8V.
To test a diode out of a circuit, connect the Meter
as follows:
1. Insert the red test lead into the VΩmA terminal and
the black test lead into the COM terminal.
2. Set the rotary switch to
is default or press SELECT button to select diode
measurement mode.
3. For forward voltage drop readings on any
semiconductor component, place the red test lead on
(Figure 6)
the component's anode and place the black test lead on
the component's cathode.
The measured value shows on the
display.
