Megger Insulation and Continuity Testers The Megger MIT410/2 200Gohm insulation and continuity testers have a redesigned case, back-stand and 6-cell battery compartment with separate fuse access. Insulation testing has been enhanced with feedback controlled test voltages to limit over-voltage to 2%, rather than the industry-standard 10-20%. All primary results are displayed in the larger digital display and repeated on the analogue arc. Auxiliary test information such as frequency, leakage current, insulation or circuit voltage is displayed in the smaller secondary digital display. A variable range has been added to allow any intermediate voltage from 50 V to 1000 V in 10 V steps.
