  • Direct current


  • Single-phase
  • Phase split with one neutral conductor
  • Three-phase - STAR with and without neutral wire
  • Three-phase - DELTA
  • Three-phase - ESTRELLA and DELTA Aron
  • With voltage and current transducers


The analyzer provides complete measurements of power quality parameters in class S, according to IEC 61000-4-30, which guarantees high accuracy of the results. Even when the temperature reaches -20°C, the measurements are reliable and the operation of the device is stable, all thanks to the built-in heater function.

Thanks to the internal battery, the analyzer does not shut down after a power failure, but keeps recording, up to 6 hours. The data is recorded on a 2 GB removable memory card. The logs can be downloaded using a USB connection or using an external reader. They can then be analysed in the free Amperis Analysis software.

Sample data

All recorded parameters, including the events indicated, can be easily read using the exclusive Amperis Analysis software. The application's advanced features allow you to view the collected results and save them to your computer's hard drive - in the form of raw data or reports.

The Amperis Analysis program is constantly being updated and developed. This means that the user will be kept up to date with the latest requirements of norms and standards.


APQM-700 fulfils its function in industry: in the hands of electricians, maintenance services etc. - as an economical and multifunctional load parameter recorder. It is also used by consumers and producers of renewable energy (wind farms, solar parks), where a 4 quadrant power analysis is required.
