Safety instructions
Before using this multimeter for the first time, always read the following instructions and pay
attention to all warnings, even if you are familiar with handling electronic devices. Store these
instructions in a safe place for future reference. If you sell the multimeter or pass it on, always
include these instructions.
WARNING! This symbol indicates important information for safe
operation of the multimeter and the safety of the user.

Electrical devices do not belong in the hands of children. Persons with disabilities should
also only use electrical devices within the scope of their abilities. Never allow children or
persons with disabilities to use electrical devices unsupervised. They may not recognise
potential risks. Batteries and small parts may cause choking resulting in death or serious
injury. Store the battery in a safe place. If a battery is swallowed, seek medical help
immediately. Also always keep plastic packaging out of reach as it poses a suffocation risk!
If smoke is produced, or there are any unusual sounds or smells, stop measuring
immediately. In these cases, the multimeter should not be used until it has been inspected by
authorised service personnel. Never inhale smoke from a potential device fire. If you have
inhaled smoke, however, consult a doctor. The inhalation of smoke can be harmful.
The test probes may be handled only behind the finger protection as otherwise there is a risk
of an electric shock when measuring!
If the multimeter or the test probes are damaged (including test lead), they must not be used.
It poses an electric shock risk!
Pay particular attention to your safety when dealing with AC voltages over 30V or DC
voltages over 60V. It poses an electric shock risk!
Never operate the multimeter when the housing is open. It poses an electric shock risk!
Ensure that you do not touch the test probes and the jacks to be measured during a
measurement in order to avoid an electric shock.
Do not use the multimeter in wet or damp environments. Also ensure that your hands and
shoes are dry as there is a risk of an electric shock otherwise!
Do not use the multimeter in the vicinity of explosive gases or vapours or in a dusty
environment. It poses a risk of explosion!
Ensure that no fire sources (e.g. burning candles) are placed on or near the multimeter. It
poses a fire hazard!
Do not exceed the maximum specified input values for the individual measuring ranges.
Otherwise, the multimeter could be damaged.
