Use the MFT5010 to test five major electrical testing requirements including insulation resistance, continuity, loop impedance and RCCB, as well as earth resistance. Additionally, the MFT5010’s Phase indicator can check a wide range of 3-Phase Power sources from 110V to 600V. Features include, Continuity Test: Live circuit warning beeps and “LIVE” displays on the LCD, Insulation Resistance, Loop impedance: Displays main voltage on the LCD, indicates Phase Angle on the LCD, with automatic overheat protection, PSC (Prospective Short-Circuit Current), RCD test: Displays main voltage and Phase Angle on the LCD, AC and DC Voltage, Earth Resistance: 3 or 2 pole measurement.
