Multifunctional measuring instrument SM-E with relay for 96x96 panel (square cutout) EKF (without verification) sm-963er

Multifunctional measuring instrument SM-E (hereinafter the instrument, meter) is a digital programmable device designed to measure parameters of three-phase 3-wire or 4-wire networks with symmetrical and asymmetrical loads, with simultaneous display of measured values and digital data transmission. The instrument provides the possibility to control, analyze, and optimize the operation of power equipment, systems, and industrial circuits. The instrument measures the following parameters: RMS values of current and voltage, frequency, active, reactive, and apparent power, active and reactive energy in forward and reverse directions; power factors, frequency; average active and reactive power; peak values.
