• Operate the product in dry interior spaces only. It must not get damp or wet. Otherwise
there is a risk of a life-threatening electric shock!
• In schools, training facilities, hobby or self-service workshops, handling of electrical
devices must be monitored by trained personnel.
• When operating on commercial premises, the relevant accident prevention regulations
of workers' compensation boards for electrical equipment must be observed.
• Live parts may become exposed when opening covers or removing parts. You must
therefore disconnect the product from all power sources before performing any
maintenance or repairs. Capacitors in the device can still carry a charge even if the
device has been disconnected from all voltage sources.
• Always lay the cables so that nobody can trip over or become entangled in them. This
poses a risk of injury.
• Check the product for damage(s) each time before use. If you discover any damages,
do not use the product. Disconnect the power supply and unplug the mains adapter
from the wall outlet. Then bring the product to a specialised workshop.
• Use only a proper mains socket (230 V/AC, 50 Hz) connected to the public power
supply.
• Do not pull the mains adapter out of the wall outlet by its cable!
• The plug must be pulled out of the socket under the following conditions:
- before cleaning the product
- during a thunder storm
- if the product is not being used over a long period.
• Make sure that the product is provided with adequate ventilation during operation. Do
not cover the ventilation openings with magazines, blankets, curtains or similar. Keep a
minimum distance of approx. 15 cm from other objects.
• When setting up the product, make sure that the cable is not pinched, kinked or
damaged by sharp edges.
• Before measuring voltages, always make sure that the meter is not set to a measuring
range for current.
• The voltage between the connection points of the meter and the earth potential must
not exceed 600 V DC/AC in CAT II
• The measuring prods have to be removed from the measured object every time the
measuring range is changed.
• Be especially careful when dealing with voltages higher than 25 V alternating (AC) or
35 V direct voltage (DC)! Even at these voltages it is possible to receive a fatal electric
shock if you touch electrical conductors.
• Check the meter and its measuring leads for damage before each measurement.
