1 Safety
The P-3 meter has been devised for the pur-
pose of voltage and circuit continuity testing,
measurement of resistance and indication of the
phase spin direction and phase identification. In
order to guarantee proper operation and adequacy
of the results the following recommendations must
be observed:
•
Before you proceed to operate the meter, ac-
quaint yourself thoroughly with the present
manual and observe the safety regulations and
specifications determined by the producer.
•
Any other application than 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 must be operated solely by appro-
priately qualified personnel with relevant cer-
tificates that entitle them to realise measure-
ments of electric installation. Operation of the
meter realised by unauthorised personnel may
result in damage to the device and constitute a
source of danger for the user.
•
The instrument must not be used for mains
and in premises of special conditions, e.g. in a
dangerous environment regarding the possibil-
ity of explosion and fire.
•
It is unacceptable to operate the following:
⇒
A damaged meter which is completely or
partially out of order,
⇒
A meter with damaged cable insulation,
⇒
A meter stored for an excessive period of
time in disadvantageous conditions (e.g.
excessive humidity). If the meter has
been transferred from a cool to a warm
environment of a high level of relative
humidity, do not realise measurements
until the meter has been warmed up to
the ambient temperature (approximately
30 minutes).
•
Do not operate a meter with an open or incor-
rectly closed battery compartment or power it
from other sources than those specified in the
present manual.
•
Voltage measurements must not last longer
than 30s. Having concluded a 30-second
measurement, the following measurement
may be performed not sooner than after 240s.
•
Limit value signalling is solely provided as
warning for the operator and not for the pur-
pose of measurement.
