• When using the measuring lines without cover caps,
measurements between the meter and the earth
potential must not be performed above the measuring
category CAT II.
• When measuring in the measuring category CAT III,
the cover caps must be pushed onto the measuring
prods to avoid accidental short circuits during meas-
urement.
• Push the cover caps onto the measuring prods until they latch. To remove, pull
the caps from the prods with a little force.
• The measuring prods have to be removed from the measured object every time
the measuring range/the measuring function is changed.
• The electrical voltage between the connection points of the meter and earth
potential must not exceed 600 V in CAT III.
• Be especially careful when dealing with voltages higher than 33 V alternate (AC)
or higher than 70 V direct voltage (DC)! Even at these voltages it is possible to
receive a potentially fatal electric shock if you touch electrical conductors.
• To avoid electric shock, make sure not to touch the connections/measuring points
to be measured directly or indirectly during measurement. During measuring, do
not grip beyond the tangible grip area limitations on the test prods and the meter.
• Check the meter and its measuring lines for damage before each measurement.
Never carry out any measurements if the protecting insulation is defective (torn,
ripped off etc.). The enclosed measuring cables have a wear indicator. When
they are damaged, a second insulation layer in a different colour becomes visible.
The measuring accessories must no longer be used and must be replaced.
• Do not use the multimeter just before, during or just after a thunderstorm (light-
ning!/high-energy overvoltage!). Make sure that your hands, shoes, clothing, the
floor, circuits and circuit components are dry.
• Never operate the product in direct proximity of:
- strong magnetic or electromagnetic fields
- transmitter aerials or HF generators
• This could affect the measurement.
