The DM-III Multitest measures and records three phase: voltage, current, voltage anomalies (sags or surges), harmonics, energy and power (active, reactive and apparent), power factor (true and displacement), frequency and phase sequence.

The DM-III Multitest F is a multitalented device that provides everything an electrical engineer or a technician needs to perform maintenance or installations on the electrical system.

It can test wires and motors for proper insulation, as well as measure the resistance of the grounding systems and resistivity of the soil.
