General characteristics
Power Quality Analyzer PQM-700 (Fig. 1) is a high-tech device providing its users with a com-
prehensive features for measuring, analysing and recording parameters of 50/60 Hz power net-
works and power quality in accordance with the European Standard EN 50160. The analyzer is fully
compliant with the requirements of IEC 61000-4-30:2009, Class S.
The device is equipped with four cables terminated with banana plugs, marked as L1, L2, L3,
N. The range of voltages measured by the four measurement channels is max. ±1150 V. This range
may be extended by using external voltage transducers.

Current measurements are carried out using four current inputs installed on short cables termi-
nated with clamp terminals. The terminals may be connected to the following clamp types: flexible
claps (marked as F-1(A), F-2(A), F-3(A)) with nominal rating up to 3000 A (differing from others only
by coil diameter); and CT clamps marked as C-4(A) (range up to 1000 A AC), C-5(A) (up to 1000 A
AC/DC), C-6(A) (up to 10 A AC) and C-7(A) (up to 100 A AC). The values of nominal measured
currents may be changed by using additional transducers - for example, using a transducer of
1000:5 ratio, the user may select C-6(A) clamps to measure currents up to 1000 A.
The device has a built-in 2 GB microSD memory card. Data from the memory card may be read
via USB slot or by an external reader.
Note
microSD card may be removed only when the analyzer is turned off. Removing the
card during the operation of the analyser may result in the loss of important data.
