P-4 ● P-5 ● P-6 – USER MANUAL
1.1 Safety symbols
This symbol located near another
symbol or terminal, indicates that the
user should read the further information
contained in the manual.
This symbol located near the terminal,
indicates that in normal use there is a
possibility of dangerous voltages.
Protection class II - double insulation
This symbol indicates that the device
must not be disposed of into any
household waste containers, but must
be provided to a designated collection
point for electronic waste.
The device meets the legal requirements
of the European Union.
CAT Measurement category of the instrument.
1.2 Safety restrictions
The different indicating signals of the voltage
detector (including the ELV limit indication) are
not to be used for measuring purposes.
The voltages marked on the voltage detector
are nominal voltages or nominal voltage rang-
es.
The voltage detector is only to be used on in-
stallations with the specified nominal voltages
or nominal voltage ranges.
The actual measurement value can
be determined using the LCD display.
Before using a voltage detector with audible
indicator at locations with a high background
noise level, it has to be determined whether
the audible signal is perceptible.
1.3 Safety advices
Depending on the internal impedance of the volt-
age detector, in case of presence of interference
voltage there will be a different capability of indi-
cating the presence or absence of operating volt-
age.
Low-impedance voltage tester (impedance
<100 kΩ). Interference voltage is suppressed or
reduced.
