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 .
3. For forward voltage
drop readings on
any semiconductor
component, place the
red test lead on the
component's anode and
place the black test lead
on the component's
cathode.
The measured value
shows on the display.

Note:
• In a circuit, a good diode should still produce a
forward voltage drop reading
of 0,5V to 0,8V; however, the
reverse voltage drop reading
can vary depending on the
resistance of other pathways
between the probe tips.
• Connect the test leads to
the proper terminals as said
above to avoid error display.
The LCD will display "1"
indicating
wrong connection. The unit
of diode is Volt (V), displaying
the
voltage-drop value.
• When diode testing has been
completed, disconnect the
connection
testing leads and the circuit
under test.
