To test a diode out of a circuit, connect the Meter as follows:
1. Insert the red test clip into the
Ω
°
))) terminal and
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.
