D) Ac Voltage Mode ("Mv "); E) Dc Voltage Mode ("V ") - VOLTCRAFT VC271 TRMS Bedienungsanleitung

d) AC voltage mode ("mV
Follow the steps below to measure mV/DC voltages
- Switch on the DMM and select the "mV
"DC" and "mV" will appear on the display.
- Press the "SELECT" button on the control dial to switch to "AC"
mode.
- "AC", "TRMS" and "mV" will appear on the display.
- Plug the red lead into the V terminal (G) and the black lead into the
COM terminal (H).
- Connect the two measuring probes in parallel to the object that
you want to measure (e.g. generator or circuit).
- The measurement will appear on the display.
- After taking a measurement, remove the leads from the measured
object and switch off the DMM.
The "V/AC" range has an input resistance of ≥10 MΩ.
This means that there is almost no load on the circuit.
e) DC voltage mode ("V
Follow the steps below to measure DC voltages:
- Switch on the DMM and select the "V
"DC" and "V" will appear on the display. For lower voltages up to
max. 400 mV, select the "mV
- Plug the red lead into the V terminal (G) and the black lead into the
COM terminal (H).
- Connect the two measuring probes in parallel to the object that
you want to measure (e.g. battery or circuit). Connect the red
measuring probe to the positive pole and the black measuring
probe to the negative pole.
- The polarity of the measurement is indicated on the display.
If "-" appears in front of a direct voltage measurement, this
indicates that the measured voltage is negative (or that the
measuring probes have been connected in reverse).
The "V DC/AC" voltage range has an input resistance of
>10 MOhm; the "mV DC" range has an input resistance of
>1000 MOhm.
- After taking a measurement, remove the leads from the measured object and switch off the DMM.
