Diode Test; Continuity Test - VOLTCRAFT VC275TRMS Bedienungsanleitung

f) Diode test
Make sure that all circuit parts, circuits and components and other objects of measurement are
disconnected from the voltage and discharged.
- Switch on the DMM and select measuring range
- Press button "SELECT" (9) 2x to switch measurement functions.
The display shows the diode symbol and the unit Volt (V). Pressing this button
again takes you to the next measuring function, etc.
- Plug the red measuring line into the Ω measuring jack (7) and the black meas-
uring line into the COM measuring jack (8).
- Check the measuring lines for continuity by connecting the two measuring
prods. The value must be approximately 0 V.
- 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 direction (UR) or the diode is faulty (interruption).
Perform a counter-pole measurement to check.
- Remove the measuring lines from the object to be measured after completion
of the measurement and switch off the DMM.
g) Continuity Test
Make sure that all circuit parts, circuits 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 symbol for continuity test now appears in the
display. Pressing this button again takes you to the next 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 value of less than 10 Ohm is measured as continuity and a beep sounds.
- If "OL" (overload) appears on the display, you have exceeded the measuring
range or the measuring circuit is interrupted.
- Remove the measuring lines from the object to be measured after completion
of the measurement and switch off the DMM.
