Taking Measurements - VOLTCRAFT VC-330 Notice D'emploi

9. TAKING MEASUREMENTS

Never exceed the maximum permitted input values. Do not touch any circuits
or circuit components if the circuit has voltages higher than 33 V ACrms or
70 V DC. Fatal hazard!
The maximum permitted voltage in the measuring circuit against ground
potential must not exceed 600 V in CAT II and 300 V in CAT III.
Before measuring, check the connected test leads for damage, such as cuts,
tears and kinks. Damaged test leads must not be used! Fatal hazard!
Do not touch the grip markings on the test prods when measuring.
Only the two test leads that are needed for measuring may be connected to the
measuring device. For safety reasons, remove all unnecessary test leads from
the measuring device when carrying out a current measurement.
Measurements in circuits rated at >33 V/AC and >70 V/DC must only be
made by qualified and trained personnel who are familiar with the relevant
regulations and the associated hazards.
Pay attention to the necessary safety information, regulations and protective
measures for your own safety.
The measured values are displayed on the current clamp's LCD display (5). The measurement
display on the current clamp covers 2000 counts (count = smallest display value). The polarity
will automatically be displayed with the (-) sign for a negative reading.
As soon as < OL > (OL=Overload) appears on the LCD display, the measuring range has
been exceeded.
There are protective caps on the angled connectors on the test leads included with the
product. Remove these before inserting the connectors into the measuring device's
sockets.
