Introduction E3-DMM-5T-2 is a multifunction, universal metering device used for overall monitoring of one- or three-phase power supply line parameters. The analyzer enables the user to make high-precision measurements of all crucial network parameters, such as: voltage and phase currents, phase-to-phase voltage, active power, reactive power, apparent po- wer, power factor.

All available safety requirements must be taken into consideration. Supply voltage E3-DMM-5T-2 multifunction meter is powered through potential terminals V1, V2, V3, N and doesn’t require auxiliary power supply. It is recommended to protect power supply and voltage circuits of the meter using 1A fuse link.
