Diode Check
A diode is an electronic switch that allows current to flow in one direction
only. It turns on when the voltage is over a certain level, generally greater
than 0.3 Volts for a silicon diode. The Meter has a special mode called
“Diode Check”. In this mode, the readings across the diode will typically
be greater than 0.7 Volts in one direction, and indicate an open circuit
in the other direction. This indicates a good diode.
NOTE: Turn the power
OFF to the circuit to be
tested.
To Check a Diode:
Select the setting
with the rotary switch.
Insert the Black lead in
COM jack.
Insert the Red lead in the
VΩRPM jack.
Touch the Red test probe
to the positive ( + ) side
of the diode.
