12. Multimeter measuring mode
Never exceed the maximum permitted input values. Do not touch any circuits or circuit compo-
nents if the circuit has voltages higher than 33 V/AC RMS or 70 V/DC. Danger of death!
Measuring is only permissible when the battery and fuse compartment are closed.
Before measuring, check the connected test leads for damage, such as cuts, tears and kinks. De-
fective test leads must no longer be used. Danger of death!
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 probe tips.
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 carried out by qualified
and trained personnel who are familiar with the relevant regulations and the associated hazards.
'OL' (overload) indicates that the measurement range has been exceeded.
In some measuring functions, a bar graph is display. The bar graph indicates the measured value as an
analogue bar display and provides an overview in relation to the current measurement range.
a) Switching the measuring instrument on and off
Turn the rotary switch (6) to select the measuring function.
The measurement ranges, excluding current measurement ranges, are automatically set to the best display area.
Always start with the largest measurement range and then switch to a smaller range, if necessary. Always disconnect
the test leads from the measured object before switching to another mode.
To switch off, move the rotary switch to the 'OFF' position. Always switch the multimeter off when it is not in use.
For storage, the test leads are best inserted into the high-impedance measurement sockets COM and V. This prevents
possible misuse in the event of subsequent measurement.
Prior to working with the measuring instrument, the enclosed battery pack must be charged and inserted.
Charging and inserting the battery pack is outlined in 'Charging and inserting the battery'.
