WARNING, risk of DANGER! The operator must refer to these instruc-
tions whenever this danger symbol appears.
Equipment protected by double insulation.
Equipment suitable for live work.
Battery.
Earth.
The CE marking indicates conformity with European directives, in
particular LVD and EMC.
The rubbish bin with a line through it indicates that, in the European Union,
the product must undergo selective disposal in compliance with Directive
WEEE 2002/96/EC. This equipment must not be treated as household
waste.
Denition of measurement categories
Measurement category IV corresponds to measurements taken at the source of
low-voltage installations.
Example: power feeders, counters and protection devices.
Measurement category III corresponds to measurements on building installations.
Example: distribution panel, circuit-breakers, machines or xed industrial devices.
Measurement category II corresponds to measurements taken on circuits directly
connected to low-voltage installations.
Example: power supply to domestic electrical appliances and portable tools.

PRECAUTIONS FOR USE
This device is protected against voltages up to 1000V with respect to earth in meas-
urement category IV.
The protection provided by the device may be compromised if it is used other than as
specied by the manufacturer and so endanger the user.
Do not exceed the maximum rated voltage and current and the measurement
category. Do not use your instrument on networks of which the voltage or category
exceeds those stated.
Comply with the conditions of use, namely the temperature, the humidity, the altitude,
the degree of pollution, and the place of use.
When handling the test probes, keep your ngers behind the physical guard.
Use connection accessories of which the measurement category and service voltage
are at least equal to those of the device.
Do not use the device if it is open, damaged, or poorly reassembled, or its acces-
sories if they seem to be damaged.
The device must be kept clean so that the condition of the cable insulators, hous-
ing, and accessories can be checked. Any component whose insulator is damaged
(even partially) must be sent for repair or scrapped.
The device is designed to be used by qualied personnel and in compliance with
national safety rules.
We recommend wearing personal protective equipment when the environment in
which the device is used makes it necessary.
All troubleshooting and metrological checks must be done by competent, accredited
personnel.
SAFETY ADVICES
Depending on the internal impedance of the voltage detector there will be a different
capability of indicating the presence or absence of operating voltage in case of the
presence of interference voltage.
A voltage detector of relatively low internal impedance, compared to the reference
value of 100 kΩ, will not indicate all interference voltages having an original voltage
value above the ELV level. When in contact with the parts to be tested, the voltage
detector may discharge temporarily the interference voltage to a level below the
ELV, but it will be back to the original value when the voltage detector is removed.
When the indication “voltage present” does not appear, it is highly recommended
installing earthing equipment before work.
A voltage detector of relatively high internal impedance, compared to the reference
value of 100 kΩ, may not permit to clearly indicate the absence of operating voltage
in case of presence of interference voltage.
When the indication “voltage present” appears on a part that is expected to be
disconnected of the installation, it is highly recommended conrming by another
means (e.g. use of an adequate voltage detector, visual check of the disconnect-
ing point of the electric circuit, etc.) that there is no operating voltage on the part
to be tested and to conclude that the voltage indicated by the voltage detector is
an interference voltage.
A voltage detector declaring two values of internal impedance has passed a perfor-
mance test of managing interference voltages and is (within technical limits) able to
distinguish operating voltage from interference voltage and has a means to directly
or indirectly indicate which type of voltage is present.
