VOLTCRAFT ET-100 - Voltage Measurement

32
b) Voltage measurement “V”
Proceed as follows to measure DC voltages “V/DC”:
- Switch on the measuring device and select measuring range “1000 V=”.
- Plug the red measuring line into the “V” measuring socket (10) and the black
measuring line into the COM measuring socket (11).
- Now connect the two test prods with the test object (battery, switch etc.).
The red test prod is the positive terminal, the black test prod is the negative
terminal.
- The polarity of the measured value is displayed with the measured value.
If a minus “-” appears for direct voltage in front of the measured value, the
measured voltage is negative (or the measuring lines have been mixed up).
- After measuring, remove the measuring lines from the test object and switch off
the measuring device.
Proceed as follows to measure AC voltages “V/AC”:
- Switch on the measuring device and select measuring range “750 V~”.
- Plug the red measuring line into the “V” measuring socket (10) and the black
measuring line into the COM measuring socket (11).
- Connect the two test prods with the test object (generator, switch etc.).
- The measured value is shown on the main display. The small display at the
bottom right shows the current battery voltage in the measuring device.
- After measuring, remove the measuring lines from the test object and switch off
the measuring device.
