1 Safety
The P-3 meter has been devised for the purpose
of voltage and circuit continuity testing, measure-
ment of resistance and indication of the phase spin
direction and phase identification. In order to guar-
antee 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 certifi-
cates that entitle them to realise measurements
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 dan-
gerous environment regarding the possibility 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. ex-
cessive humidity). If the meter has been
transferred from a cool to a warm envi-
ronment of a high level of relative humid-
ity, do not realise measurements until the
meter has been warmed up to the ambi-
ent temperature (approximately 30 min-
utes).
•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 meas-
urement, the following measurement may be
performed not sooner than after 240s.
•Limit value signalling is solely provided as warn-
ing for the operator and not for the purpose of
measurement.
