Diode Test; Continuity Check - VOLTCRAFT VC870 Notice D'emploi

f) Diode test
Make sure that all the circuit parts, switches and components and other objects of
measurement are disconnected from the voltage and discharged.
- Turn the DMM on and select measuring range
diode symbol appears in the display.
- Plug the red measuring line into the Ω measuring jack and
the black measuring line into the COM measuring jack (8) .
- Check the measuring lines for continuity by connecting
both measuring prods with one another. The value must
be approximately 0.0000 V.
- Now connect the two measuring prods with the object to
be measured (diode).
- The display shows the continuity voltage "UF" in volt (V).
If "OL" appears, the diode is measured in reverse direc-
tion (UR) or the diode is faulty (interruption). Perform a
counter-pole measurement to check.
- After measuring, remove the measuring lines from the
measured object and turn the DMM off.
g) Continuity Check
Make sure that all the circuit parts, switches and components and other objects of
measurement are disconnected from the voltage and discharged.
- Turn the DMM on and select measuring range
Press "SELECT" button to switch measurement func-
tions. The symbol for continuity check now appears in the
display. Pressing this button again takes you to the first
measuring function etc.
- Plug the red measuring line into the Ω measuring jack and
the black measuring line into the COM measuring jack (8) .
- A continuity value of less than 20 Ohm is identified as
continuity; in this case a beep sounds. The measuring
range is up to 400 Ohm.
- As soon as "OL." (overload) appears on the display, you
have exceeded the measuring range or the measuring
circuit has been interrupted.
- After measuring, remove the measuring lines from the
measured object and turn the DMM off.
