6 - DIODE TEST
Never test a diode on a live circuit
Connect the leads to the multimeter and to the terminals of the
component to be tested.
Place the selector switch on the diode function
:
- in forward direction the display gives the value of the junction in
volts (resolution 1mV)
- accuracy : ± 2% of Reading ±15mV
- open circuit voltage :
≥
3V
- short circuit current : 0.8mA
- in reverse direction the display indicates the open circuit voltage,
around 3V.
Freeze the value, by pressing the HOLD button.
With this function it is thus possible to test standard diodes, led’s
or any other semiconductor which has a junction that corresponds
to a direct voltage of less than 3V.
