10 Diode Testing and Continuity Measurement
10.1 Diode Testing
Attention!
!
Verify that the device under test is electrially dead. Ex-
ternal voltages would falsify the measurement results!
Set the function selector switch to „ .
Connect the device under test as shown.
Conducting Direction and Short-Circuit
The measuring instrument displays the forward voltage in volts.
As long as the voltage drop does not exceed the maximum
display value of 1.000 V you can test several elements con-
nected in series.
Reverse Direction or Interruption
The measuring instrument displays a voltage of „OL“.
Note!
Resistors and semiconductor paths in parallel to the
diode distort the measurement results!
