M) Continuity Test; N) Capacitance Measurement - VOLTCRAFT VC281 TRMS Operating Instructions Manual

m) Continuity test

Ensure that all objects that you want to measure (including circuit components, circuits and com-
ponent parts) are disconnected and discharged.
- Switch the DMM on and select
- Press the "SELECT" button once to switch to the mode. The
continuity test symbol and the Ω symbol will appear on the
display. Press the button again to switch to the next mode.
- I nsert the red test lead into the Ω measurement socket (G) and
the black test lead into the COM measurement socket (H).
- I f the measured resistance is equal to or less than 10 Ω, the
multimeter will beep to indicate continuity. There is no further
beeping from >100 Ω. The continuity test measures resist-
ances of up to 600 Ω.
- "OL" (overload) indicates that the measurement range has
been exceeded or that the circuit is broken.
- After taking a measurement, remove the leads from the meas-
ured object and switch the DMM off.

n) Capacitance measurement

Ensure that all objects that you want to measure
(including circuit components, circuits and com-
ponent parts) are disconnected and discharged.
Always pay attention to the polarity when using
electrolytic capacitors.
- Switch the DMM on and select the measurement range
- Insert the red lead into the V socket (G) and the black lead into
the COM socket (H).
- "nF" will appear on the display.
Due to the sensitive measuring input, the display may
show a reading even with "open" test leads. Press the
"REL" button to measure small capacities (<600 nF).
The indicator is then set to "0". Auto range is thereby
disabled.
- Connect the two measuring probes (red = positive, black =
negative) to the object that you want to measure (capacitor).
The capacitance will be shown on the display after a few sec-
onds. Wait until the display stabilises. This may take a few
seconds for capacitances greater than 40 µF.
- "OL" (overload) indicates that the measurement range has been exceeded.
- After taking a measurement, remove the leads from the measured object and switch the DMM off.
