RTFM

Diode testing
1. Turn the function switch to "".
2. Plug the black lead into the "COM" input terminal and the red lead 
into the "V- -Hz-
" input terminal.
(Note: The red lead is positive.)
3. Apply the probes to the diode to be tested. With a non-faulty silicon 
diode, the voltage shown in the forward direction will be
between 0.500 and 0.900V. With a faulty diode, "000" (short-circuit) or 
a reading of approx. 3.2V (open circuit) will be
shown.
4. When tested in the opposite direction (blocking direction), a reading 
of approx. 3.2V will appear for a non-faulty diode and
"000" (short circuit) or a different reading of less than 3.2V for a 
faulty one.

Thanks!

Ich las nicht Netzgerät sondern Multimeter und der Hersteller sagt:

These meters are mains or battery-powered measuring....

Labormultimeter...
