Extech Instruments’ Extech MG320 is a CAT IV 20GΩ/1000V insulation tester with integrated True RMS multimeter. The MG320 is a solution for industrial predictive maintenance programs which include routine insulation testing of electrical and electronic equipment and cables. The rugged new tool puts insulation testing up to 1kV (1000V) and a 20GΩ range in a portable tester and offers users five test voltages (50V, 100V, 250V, 500V, 1000V) and step voltage in 10% increments from 50% to 120% of range. For advanced insights, the MG320 features both Polarization Index (PI) and Dielectric Absorption Ratio (DAR) modes as well as continuity and low resistance testing with 20kΩ range and zero function. The comparison mode permits technicians to customize Pass/Fail values for the varying requirements of insulation tests on gear around a job site. Insulation testing length can be configured with a programmable timer. A locking function mode enables hands-free use while readings are displayed on a large, backlit dual display with digital readout and analog bar graph. During testing, up to 99 readings can be stored and readings on the display can be frozen using Data Hold. After testing, the meter internally discharges the voltage test signal. Technicians can also measure AC and DC voltage. The meter comes complete with tilt stand, test leads, alligator clip, six AA batteries, and soft storage case. The meter is backed by a Category IV 600V overvoltage safety rating and a one year warranty.
