B) Voltage Measuring "V - VOLTCRAFT VC275TRMS Bedienungsanleitung

b) Voltage Measuring "V"

Proceed as follows to measure direct voltages "DC" (V
- Switch on the DMM and select measuring range "V
voltages up to 600 mV, select the measuring range "mV
- Plug the red measuring line into the V measuring jack (7) and the
black measuring line into the COM measuring jack (8).
- Connect the two measuring prods to the object to be measured
(battery, circuit, etc.). The red measuring prod indicates the positive
pole, the black measuring prod the negative pole.
- The polarity of the respective measured value is indicated on the
display together with the current measured value.
If a minus "-" appears in front of the measured value for direct
voltage, the measured voltage is negative (or the measuring lines are swapped).
The voltage range V DC/AC" has an input resistance of >10 MΩ. The mV-range has an input resistance of >1
GΩ. With the measuring inputs open, the high input resistance may cause an undefined measured value to
be displayed; however, this does not influence the measuring result.
- Remove the measuring lines from the object to be measured after completion of the measurement and switch off
the DMM.
Proceed as follows to measure alternating voltages "AC
- Switch on the DMM and select measuring range "V
"TRMS AC" appears in the display. For lower voltages up to 600 mV, select the measuring range "mV
the grey "SELECT" button at the dial switch (9). "TRMS AC" appears in the display.
- Plug the red measuring line into the V measuring jack (7) and the black measuring line into the COM measuring
jack (8).
- Connect the two measuring prods to the object to be measured (generator, circuit, etc.).
- The measured value is indicated on the display.
- Remove the measuring lines from the object to be measured after completion of the measurement and switch off
the DMM.
