Diode Check:
To ensure a proper functioning diode, the meter will develop a
voltage across the component from a test current. The diode
test function allows for measurements of forward voltage drops
across diode and transistor junctions.
1. Turn off power to the device or circuit that is being tested
and discharge all capacitors.
2. Plug the black test lead into the COM port and the red test
lead into the Hz V
Ω
µA port.
3. Set the rotary switch to the position.
5. Connect the test leads to the diode.
Forward bias:
Good = 0.4 to 0.9V
Bad = 0 or
≥
2.0V
Reverse bias:
Good = OL
Bad = < 2.0V
