• Before taking any measurements, make sure that both
the area to be tested (e.g. a line), the test device and
the accessories used (e.g. connection cable) are in proper
working order. Test the device by connecting it to known
voltage sources (e.g. a 230 V socket in the case of AC
testing or a car battery in the case of DC testing).
• Observe the safety precautions of local and national
authorities relating to the correct use of the device and any
prescribed safety equipment (e.g. electrician's safety gloves).
• The device must not be connected to voltages for longer than
30 seconds.
• The device is not suitable for unsupervised use.
• If you have to take hold of the measuring spikes, do so by
the grip sections only. Do not touch the measuring contacts
whilst the measurement is being taken.
• Do not work alone in the vicinity of hazardous electrical
installations and only under the guidance of a qualified
electrician.
Additional information on use
Observe the technical safety regulations for working on electrical
systems, especially: 1. Safely isolating from power supply,
2. Securing to prevent system being switched on again,
3. Checking zero potential, two-pole, 4. Earthing and short-
circuiting, 5. Securing and covering adjacent live components.
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.
