Description

The device ShchM96 is designed to measure electrical parameters of three-wire or four-wire three-phase AC networks with frequency 45-55 Hz. It is used in data acquisition systems to transfer measurement results to upper level systems or as a universal measuring device, instead of different electrical measuring devices: ammeters, voltmeters, wattmeters, varmeters, frequency meters. The device provides the possibility of: reprogramming of display ranges; setting of min and max settings within the measuring range; regulation of indication brightness; connection of external indication modules. The instrument is included in the State Register of measuring instruments of the Russian Federation No. 63217-16. Interverification interval - 10 years.
