Taking Measurements; Switching On The Multimeter - VOLTCRAFT VC-532 AC Mode D'emploi

9. 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! Fatal hazard!
Before measuring, check the connected test leads for damage, such as cuts, tears and kinks. Never
use damaged test leads, as this may cause a fatal electric shock!
Before working with the multimeter, check that the measuring function is working correctly. Always
start by taking a measurement on a known source and monitor the display carefully. A faulty mul-
timeter may present a fatal hazard for the user. In the event of a fault, inspect the multimeter and
consult a technician if necessary.
When taking measurements, do not touch any area beyond the grip markings on the test probes
and the multimeter.
Only connect the two test leads that you require to take measurements. For safety reasons, remove
all unnecessary test leads from the device before taking a 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.
"OL" (overload) indicates that the measuring range has been exceeded.
a) Switching on the multimeter
The multimeter is turned on and off via the rotary dial. Turn the rotary control (F) to select the desired mode. To turn
the multimeter off, move the control dial to the "OFF" position. Always turn the multimeter off when it is not in use.
The multimeter conducts a short function test after it is switched on. During the function test, all symbols will appear
on the display.
Insert the batteries before using the multimeter. For more information on inserting/replacing the
batteries, see "Cleaning and maintenance".
