To test a diode out of a circuit, connect the Meter as follows:
1. Insert the red test clip into the
black test clip into the COM terminal.
2. Set the rotary switch to
3. 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.
Note:
*
In a circuit, a good diode should still produce a forward
voltage drop reading of 0,5 V to 0,8 V; however, the
reverse voltage drop reading can vary depending on the
resistance of other pathways between the probe tips.
*
Connect the test clips to the proper terminals as said
above to avoid error display. The LCD will display "1"
indicating open-circuit for wrong connection. The unit of
diode is Volt (V), displaying the positive-connection
voltage-drop value.
*
When diode measurement has been completed disconnect
the connection between the testing clips and the circuit under
test and remove the testing clips and the circuit under test and
remove the testing clips away from the input terminals of the
Meter.
