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. 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. It can test wires and motors for proper insulation, as well as it can measure the resistance of the grounding systems and resistivity of insulation, as well as it can measure the resistance of the grounding systems and resistivity of the soil. On board memory makes it a perfect tool for preventing maintenance applications.
