September 5, 2018 — The MIT485/2TC-LG2 replaces Megger’s original MIT480 range tester. The instrument features fixed test voltages of 50V, 100V, 250V and 500V, as well as variable test voltages from 10V to 500V.

Insulation testing can be performed up to 100GΩ at 500V. A grated access feature to 500V prevents accidental application of high voltage to sensitive equipment. Featuring a three-terminal connection for tip, ring and ground testing, users can select the measurement pair from the new T-R-G button the front panel, omitting the need to connect and disconnect leads to perform the full range of testing on a cable pair.

The MIT485/2TC-LG2 also offers fast continuity testing with a user-selectable test current of 20 mA or 200mA. Continuity testing covers 0.01Ω to 1 MΩ without the need for manual range switching. The unit provides DC and Trms AC voltage measurements up to 600V and offers onboard test result storage, as well as Bluetooth downloading capability.
