The EMM5 is a multifunctional device for acquisition and calculation of many measurements which are important in 3-phase, 4-wire electrical power distribution circuits. It can be used in low voltage systems or with higher voltages by means of voltage measurement transformers.

The EMM5 power analyzer has been designed to provide a great variety of information from the power distribution system it supervises. A big liquid crystal display with backlight provides a good visibility even in poor light conditions. Four adaptive soft-keys provide easy and intuitive usage. A basic set of standard values (currents, voltages and powers) is calculated from the measured input data.

Nearly all calculated values are true RMS (TRMS) values, which means that they are correct even if the waveform is not a sine function, and there is facility to measure the harmonics upto the 63rd level on voltage and current.
