Safety - Sonel P-4 Manual De Uso

Voltage testers of P type are used to test voltage,
continuity of connections, diode tests, checking
phase rotation, and - in some models - resistance
measurements and identification of phases.
In order to provide conditions for correct operation
and the correctness of the obtained results, the fol-
lowing recommendations must be observed.

Before you proceed to operate the device, ac-
quaint yourself thoroughly with this manual and
observe the safety regulations and specifications
defined by the producer

Any application that differs from those specified
in the present manual may result in a damage to
the device and constitute a source of danger for
the user.

The device should be operated only by suitably
qualified persons having the necessary permis-
sions to carry out measurements on electrical
systems. Unauthorized use of the tester may re-
sult in its damage and may be a source of seri-
ous hazard to the user.

Comply with safety requirements and regulations
in force in your country when working with the de-
vice. This also applies to the use of personal pro-
tective equipment to protect against electric
shock.

Before using the device, please check its accura-
cy on the known voltage source.

Do not perform measurements in explosive at-
mosphere (e.g. in the presence of flammable
gases, vapours, dusts, etc.). Using the meter in
such conditions may result in sparking and cause
an explosion.

It is unacceptable to operate the device when:
 it is damaged (including cracks and missing
parts of the housing) and completely or par-
tially out of order,
 its cable insulation is damaged,
 it was stored for an excessive period of time
in disadvantageous conditions (e.g. exces-
sive humidity)After moving the device from
a cool to a warm place with a high level of
relative humidity, do not start measure-
ments until the device is warmed up to the
ambient temperature (approximately 30
minutes)

Do not use the tester when the battery compart-
ment is removed or open. Do not power the me-
ter from other sources than those mentioned in
this manual.

When the low battery indicator lights up, test re-
sults may be incorrect.

Do not perform voltage measurements for longer
than 30 seconds. After the measurement period
of 30 s, the next measurement may be made no
earlier than after 240 s.
