3. Set the Threshold function.
The default value is set as 2V before leaving the factory. The value can be
changed by using the direction keys.
You also can execute the Diode
measurement directly without modification.

4. Set the Beeper function.
Press
[

to turn the Beeper on or off. If the circuit is continuous, the
instrument will beep once when the Beeper is turned on.
5. Read the measurement result.
6. Reverse the probes and measure the voltage in the diode once more.
Evaluate the diode according to the following rules:
●
If the Multimeter shows “overload” when in reverse bias model, it indicates
that the diode is normal.
●
If the Multimeter shows voltage about 0V and the instrument beeps
persistently when in forward and reverse bias model, it indicates that the
diode is short.
●
If the Multimeter shows “overload” when in forward and reverse model, it
indicates that the diode is open.
Note:
Before testing diode, please cut off the power and discharge all the
high-voltage containers to avoid damages to the Multimeter.
