Taking Measurements - VOLTCRAFT VC891 Bedienungsanleitung

11 Taking measurements

Never exceed the maximum permitted input values. Never touch
circuits or parts of circuits when they may contain voltages greater
than 33 V/ACrms or 70 V/DC! Danger to life!
Measurements can only be taken when the battery and fuse com-
partment is closed. Cables cannot be inserted when the compart-
ment is open.
Before measuring, check the connected test leads for damage,
such as cuts, tears and kinks. Never use defective test leads! Dan-
ger to life!
When taking measurements, do not touch any area beyond the grip
markings on the probe tips.
Only connect the two test leads that you require to take measure-
ments. For safety reasons, remove all unnecessary test leads from
the multimeter before taking a measurement.
Measurements in electrical circuits rated at >33 V/AC and >70 V/DC
must only be carried out by qualified and trained personnel who are
familiar with the relevant regulations and the associated hazards.
Check the multimeter for functionality before each measurement. An incorrect check
result indicates a possible malfunction. The multimeter must be checked.
"OL" (overload) indicates that the measurement range has been exceeded.
