PQM-701 / 701Z /701Zr  Power Quality Analyser
PQM-701 series
Software - 'Sonel Analysis': 

„SONEL Analysis” the tablet version of the application is necessary to work with the PQM-710 and PQM-711.


This software allows:

  • analyzer configuration,

  • reading data from the analyzer,

  • network parameters check in real time (the ability to read data

       through GSM modem),

  • data deleting in the analyzer,

  • data presentation in tables,

  • data presentation in diagrams,

  • data analysis according to EN 50160 or according to user defined conditions,

  • independent service of multiple analyzers,

  • software upgrade through the Internet.

Analyzer Configuration

The software enables configuration of all analyzer’s parameters. The configuration is made on the computer and later transferred to the analyzer. The configuration settings can be stored on hard drive or other data storage devices to be used later.

Live Mode

“SONEL Analysis” software enables reading of selected parameters and their graphic presentation in real time. These parameters are measured independently of the registration saved in the memory.

Sonel Analysis enables compensation of noise current for clamps on inactive objects. User can Check:

- voltage and current diagrams (oscilloscope)

- diagrams of voltage and current in time function,

- scope phasor,

- different parameters values,

- harmonics and harmonics’ power,

- interharmonics.

Data Analysis

With “SONEL Analysis” software user can read data stored on the memory and analyze them. Data from the analyzer can be stored on tablet memory and be used later. This feature enables data archiving.

The user can analyze the data from the device.

There is a choice of:

General – all data are shown with dots (Measurements, Events and Waveforms),

Measurements – all measured values registered in averaging time are shown in table (voltage, frequency, etc.),

Events – all detected events are shown in table (dips, swells, interruptions, etc.),

Configuration – display of settings, according to which data were recorded

Key Features:


  • power to the analyzer is supplied from testedmains (internal power supply) and is used in all types of networks from 110V to 690V, with

      particular emphasis on measurements at low

      voltage poles, due to the ease of connection.


  • has an independent power supply socket,especially suited for voltage measurements for transformers and DC circuits.


  • has an independent power supply socket and an additional RS-232 interface to control a GPRS modem.

  • PQM-701Z/701Zr have an independent power supply socket, especially suited for voltage measurements for transformers and DC circuits.

  • PQM-701 series analyzers can operate in any climatic conditions

       (- 20 °C ... + 55 °C).
