5. Safety instructions

Read the operating instructions and safety information carefully. If you do not follow the safety
instructions and information on proper handling in this manual, we assume no liability for any
resulting personal injury or damage to property. Such cases will invalidate the warranty/guarantee.
• This device was shipped in a safe condition.
• To ensure safe operation and avoid damaging the product, always observe the safety information and
warnings in these instructions.
• For safety and approval reasons, do not attempt to convert and/or modify the device.
• Consult a technician if you are not sure how to use or connect the device.
• Measuring instruments and their accessories are not toys and should be kept out of the reach of children.
• Always comply with accident prevention regulations for electrical equipment when using the product in
industrial facilities.
• In schools, educational facilities, hobby and DIY workshops, measuring devices must be operated under
the responsible supervision of qualified personnel.
• Before each measurement, always make sure that the meter is set to the correct measurement mode.
• When using measuring probes without protective caps, measurements
between the multimeter and the earth potential must not exceed the CAT II
measurement category.
• When taking CAT III and CAT IV measurements, the cover caps must be
placed on the probe tips (max. length of exposed contacts = 4 mm) to avoid
accidental short circuits. These are supplied with the device.
• Always remove the test probes from the measured object before changing the measurement mode.
• The voltage between the multimeter connection points and earth must never exceed 600 V DC/AC in
CAT IV.
• Exercise particular caution when dealing with voltages exceeding 33 V/AC or 70 V/DC. Touching electri-
cal conductors at these voltages may result in a fatal electric shock.
• To prevent an electric shock, do not touch the measuring points when taking measurements, either
directly or indirectly. When taking measurements, do not grip beyond the grip markings on the multimeter
and test probes.
• Check the measuring device and test leads for signs of damage before each measurement. Never take
measurements if the protective insulation is damaged (torn, missing, etc.). The measuring cables come
with a wear indicator. If a cable is damaged, a second layer of insulation will become visible (the second
layer of insulation is a different colour). If this happens, discontinue use and replace the measurement
accessory.
• Do not use the multimeter before, during or after a storm (risk of electric shock / power surge). Ensure
that your hands, shoes, clothes, the floor, circuit and circuit components are dry
