VOLTCRAFT VC731 Notice D'emploi page 46

• Adjust the current injection probe to the desired measuring range before
each measurement. Incorrect measurements may destroy the product!
Ensure before every voltage measurement that the current injection probe is
not set to a measuring range for current.
• The measuring prods have to be removed from the measured object every
time the measuring range is changed.
• To avoid electric shock, make sure not to touch the connections/measuring
points to be measured directly or indirectly during measurement. Never
reach beyond the noticeable grip area marks at the measuring prods during
measurements.
• Remove the dust protection caps at the connection sockets before
connecting the measuring lines. Always install them after each measurement
to avoid contamination of the contacts.
• Observe the description of the figures in each chapter for each
measurement. Incorrect measurements may destroy the product.
• The voltage between the connection points must not exceed the voltage
indicated in the chapter "Technical Data".
• Be especially careful when dealing with voltages >25 V/AC or >35 V/DC!
Even at these voltages it is possible to receive a potentially fatal electric
shock if you touch electrical conductors.
• Never touch the measuring prods during measurement!
• During each measurement, observe that the connections/measuring points
do not touch. Danger of short-circuit!
• For each measurement, ensure that the current probe sensor does not crush
any objects such as cables.
• Avoid operation in direct proximity of strong magnetic or electromagnetic
fields, transmitter aerials or HF generators, since the measured value can be
falsified here.
