Megger MIT481/2 Insulation Tester



Product Description

The Megger  MIT481/2 insulation and continuity tester replaces the original MIT480 range and is designed specifically for the Telecommunications and Cable testing markets. The new units feature a redesigned case, back-stand, and 6 cell battery compartment with separate fuse access. All instruments are over molded for increased protection and achieve an IP54 weatherproof rating.

Three terminal measurement design 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 are required.

Alternatively the Megger MIT481/2 can be used as a conventional Two Terminal instrument.

The feedback controlled insulation test voltage is now accurate to +2% -0% compared to the original +20%, providing a more accurate test voltage without the risk of over-voltage damage to circuits. A variable range allows the exact test voltage to be selected from 10 V up to 500 V. The output test voltage is maintained within the tolerance or -0% +2% +2 V. The voltage is feedback controlled to ensure it remains within
specification throughout the full test range. The actual test voltage is displayed on the smaller digital readout, with the measurement on the larger digital display.
