Diode Test; Continuity Check - VOLTCRAFT VC280 Mode D'emploi

h) Diode Test
Make sure that all the circuit parts, switches and components and other objects of
measurement are disconnected from the voltage and discharged.
- Switch on the DMM and select measuring range
- Press "SELECT" (9) button to switch measurement functions. The diode
symbol appears in the display. Pressing this button again takes you to
the next measuring function.
- Plug the red measuring line into the Ω measuring jack (7) 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 V.
- Now connect the two measuring probes 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 direction (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.
i) Continuity Check
Make sure that all the circuit parts, switches and components and other objects of
measurement are disconnected from the voltage and discharged.
- Switch on the DMM and select measuring range
- Press "SELECT" (9) button twice to switch measurement functions. 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 (7) and the black
measuring line into the COM measuring jack (8) .
- A continuity value of less than 10 Ohm is identified as continuity; in this
case a beep sounds.
- If "OL" (overload) appears on the display, you have exceeded the measuring range or the measuring
circuit has been broken.
- After measuring, remove the measuring lines from the measured object and turn the DMM off.
