Diode Test - VOLTCRAFT VC-666 Bedienungsanleitung

If you carry out a resistance measurement, make sure that the mea-
suring points which you contact with the test prods are free from dirt,
oil, solderable lacquer or the like. An incorrect measurement may
result under such circumstances.
c) Diode test
Make sure that all the circuit parts, switches and components
and other objects of measurement are disconnected from the
voltage at all times.
Select the measuring range
- Check the measuring leads for continuity by connecting both measuring prods to
one another. After that the value must be approx. 0.
- Now connect the two measuring prods with
the object to be measured (diode).
- The display shows the continuity voltage in
Millivolt (mV). Usual voltage values: silicon
diode ca. 700 mV, germanium diode ca. 250
mV). If „1" is indicated, the diode is measured
in reverse direction or the diode is faulty
(interruption).
- After you finish testing, always switch the measuring device off. Turn the rotary
switch to „OFF".
