Safety instructions
Dealing with electromagnetic radiation
• The measuring device complies with electromagnetic
compatibility regulations and limits in accordance with the
EMC Directive 2014/30/EU which is covered by the Radio
Equipment Directive 2014/53/EU.
• Local operating restrictions – for example, in hospitals, aircraft,
petrol stations or in the vicinity of people with pacemakers –
may apply. Electronic devices can potentially cause hazards or
interference or be subject to hazards or interference.
Symbols
Fig. B: Hazardous electrical voltage warning: Unprotected live
components inside the device housing may pose a risk of electric
shock.
Fig. C: Danger area warning
Fig. D: Protection class II: The test device has reinforced or
double insulation.
CAT II: Overvoltage category II: Single-phase consumers that
are connected to standard sockets, e.g. household appliances,
portable tools.
CAT III: Overvoltage category III: Equipment in fixed
installations and for applications where specific requirements
with regard to the reliability and availability of equipment
have to be met, e.g. circuit-breakers in fixed installations and
devices used in industrial applications which are permanently
connected to the fixed installation.
CAT IV: Overvoltage category IV: Devices such as electricity
meters, overcurrent circuit breakers and ripple-control units,
which are intended for use at or near the infeed into the
electrical installation of buildings, and specifically from the
main distribution to the supply system.

Insertion of batteries (see Fig. E)
Open the battery compartment and insert batteries according
to the symbols. Be sure to pay attention to polarity.
The device is ready for use immediately once the
!
batteries have been inserted. It does not have a
separate ON/OFF switch and is therefore always active.
As from a measuring voltage of 50 V, the device
operates in emergency mode even without batteries.
