Extech MG320 CAT IV Insulation Tester/True RMS MultiMeter is ideal for industrial predictive maintenance programs. The rugged tool combines testing up to 1kV (1000V) and a 20GO range for testing motors, generators, transformers and other electrical components. Five test voltages (50V, 100V, 250V, 500V, 1000V) are available with step voltage in 10% increments from 50% to 120% of range. For advanced testing, the meter features both Polarization Index (PI) and Dielectric Absorption Ratio (DAR) modes along with continuity and low resistance testing with 20kO range and zero function.
