MIT481/2

The MIT481/2 from Megger is a MIT480 mk2 series insulation tester. This insulation and continuity testers replace the original MIT480 range and is designed specifically for the telecommunications and cable testing markets. The insulation testing range up to 500V and 100Gohm and continuity testing from 0.01ohm to 1Mohm. Three terminal measurement permits the connection of all three test leads for A, B and E (or tip, ring and ground). The measurement pair is selected from the A-B-E (T-R-G) button on the front panel. Selection is confirmed in the display. No disconnection of test leads to measure individual pairs is required. Alternatively can be used as a conventional two terminal instrument. Meets EN 61010-1 (1995) to 600V phase to earth, category IV safety protection. It features a redesigned case, back-stand and 6 cell battery compartment with separate fuse access. All instruments are over-moulded for increased protection and achieve an IP54 weatherproof rating.
