1 General Information
1.1 Safety
PQM-702 and PQM-703 are designed to measure, record and analyze power qual-
ity parameters. In order to provide safe operation and correct measurement re-
sults, the following recommendations must be observed:
 Before you proceed to operate the analyzer, acquaint yourself thoroughly with the present man-
ual and observe the safety regulations and specifications provided by the producer.
 Any application that differs from those specified in the present manual may result in damage to
the device and constitute a source of danger for the user.
 Analyzers must be operated only by appropriately qualified personnel with relevant certificates
authorizing the personnel to perform works on electric systems. Operating the analyzer by un-
authorized personnel may result in damage to the device and constitute a source of danger for
the user.
 The device must not be used for networks and devices in areas with special conditions, e.g.
fire-risk and explosive-risk areas.
 It is unacceptable to operate the device when:
 it is damaged and completely or partially out of order,
 its cords and cables have damaged insulation,
 Do not power the analyzer from sources other than those listed in this manual.
 If possible, connect the analyzer to the de-energized circuits.
 Opening the device socket plugs results in the loss of its tightness, leading to a possible damage
in adverse weather conditions. It may also expose the user to the risk of electric shock.
 Repairs may be performed only by an authorized service point.
Measurement category of the whole system depends on the acces-
sories used. Connecting analyzer with the accessories (e.g. current
clamps) of a lower measurement category reduces the category of
the whole system.
Note
 Do not unscrew the nuts from the cable glands, as they are perma-
nently fixed. Unscrewing the nuts will void the guarantee.
 Do not handle or move the device while holding it only by its ca-
bles.
The icon with the analyzer name is placed next to sections of
the text that refer to specific features of the analyzer, particularly to availa-
bility/unavailability of a given function.
All other parts of the text relate to both types of the analyzer.
