Direct Current Measuring "A Dc - VOLTCRAFT VC-125 Notice D'emploi

c) Direct Current Measuring "A DC"
The maximum permissible voltage in the measuring circuit against ground potential must not
exceed 600 V in CAT II and III.
Current measurement always takes place in series with the consumer. Before connecting the meter, the circuit must
be powered down. After the end of measuring, power down the circuit before removing the measuring lines. This
prevents the occurrence of light arcs.
Current measurements >5 A must only be performed for max. 30 seconds and with measuring breaks of 15 minutes.
Proceed as follows to measure direct voltages (A DC
- Switch on the DMM by the dial switch (3) and select the measuring
range "10 A".
- Plug the red measuring line into the 10A measuring jack (4) and the
black measuring line into the COM measuring jack (5).
- Connect the two measuring prods in series with the
consumer. The red measuring prod indicates the pos-
tive pole, the black measuring prod the negative pole. Switch on
the measuring circuit.
- The measured value is indicated on the display.
When a minus "-" appears in front of the measured value when measuring direct current, the current has the
opposite direction (or the measuring lines have been swapped).
- Power down the measuring circuit after the end of measuring and remove the measuring prods from the measured
object. Switch off the device. Turn the dial switch to "OFF".
