Continuity Check; Diode Test - VOLTCRAFT R-200 Bedienungsanleitung

e) 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 "MODE" (4) to switch measurement functions. The symbol for con-
tinuity check now appears in the display. Pressing this button again takes
you to the next measuring function.
- Plug the red single measuring lead into the Ω -measuring socket "E2"
(10) and the black measuring lead into the COM measuring socket "E1"
(13).
- A continuity value of less than 35 Ohm is identified as continuity; in this
case a beep sounds.
- If "OL" (overload) appears on the display, you have exceeded the mea-
suring range or the measuring circuit has been broken. Perform a
counter-pole measurement to check.
- After measuring, remove the measuring leads from the measured object
and turn the DMM off.
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
- Press "MODE" (4) twice to switch measurement functions. The diode
symbol appears in the display. Pressing this button again takes you to
the first measuring function etc.
- Plug the red single measuring lead into the Ω -measuring socket "E2"
(10) and the black measuring lead into the COM measuring socket "E1"
(13).
- Check the measuring leads for continuity by connecting both measuring
probes 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 leads from the measured object
and turn the DMM off.
Silicon diodes exhibit a continuity voltage (UF) of approx.
0.4 – 0.9 V.
