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 VDC! Fatal hazard!
Before measuring, check the connected test leads for damage, such as cuts, tears and kinks. De-
fective test leads must no longer be used. Fatal hazard!
Before working with the multimeter, check that the correct measuring function is selected for the
measurement. Always perform a measurement on a known measurement source first and check
that the display is correct. A multimeter malfunction may pose a life-threatening situation to the
user. In the event of an incorrect display, check the multimeter and, if necessary, contact a special-
ist to have the device examined.
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 switch (3) to the corresponding measuring
function. 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. For production reasons, during the function test, some icons may appear in the display but they are
not required by this model type.
Insert the batteries before using the multimeter. For more information on inserting/replacing the
batteries, see "Cleaning and maintenance".
