Megger MIT485/2 Analog Digital Insulation Tester
The MIT485/2TC-LG2 insulation and continuity tester replaces the original MIT480 range and is designed specifically for the Telecommunications and Cable testing markets. The new unit features a redesigned case, back-stand, and 6 cell battery compartment with separate fuse access. The instrument is over-molded for increased protection and achieves an IP54 weatherproof rating.
THREE TERMINAL CONNECTION
Three terminal measurement permits the connection of all three test leads for Tip, Ring and Grounds. The measurement pair is selected from the T-R-G button on the front panel (new). Selection is confirmed in the display. No disconnection of test leads to measure individual pairs are required.
INSULATION RESISTANCE TESTING:
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.
Features:
- Test voltages - 50 V, 100 V, 250 V, and 500 V.
- Variable test voltage - Adjustable test voltage from 10 V to 500 V.
- 2 % test voltage accuracy - The output test voltage is maintained within the tolerance or-0% +2% +2 V.
- PASS/FAIL (✓/x) indication - PASS or FAIL (✓/x) displayed depending on threshold voltage.
- Stabilized test voltage - The voltage is feedback controlled to ensure it remains within specification throughout the full test range.
- Test voltage display - The actual test voltage is displayed on the smaller digital readout, with the measurement on the larger digital display.
- Test range - Insulation testing up to 100 GΩ@ 500 V.
- Measurement range displayed – The test range is displayed during selection.
- Measurement voltage display – The measurement voltage is displayed during the test.
