Insulation tester performs at up to 100GΩ at 500V

An insulation and continuity tester designed specifically for the telecommunications and cable testing markets has been announced by Megger.  The MIT485/2TC-LG2 replaces Megger’s original MIT480 range tester. This handheld 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 gated access feature to 500 V prevents accidental application of high voltage to sensitive equipment. The instrument features a three-terminal connection for tip, ring and ground testing. 

The measurement pair is selected from the new T-R-G button on the front panel, omitting the need to connect and disconnect leads to perform the full range of testing on a cable pair.

Feedback-controlled insulation test voltage is accurate to +2% - 0%, providing a more accurate test voltage without the risk of over-voltage damage to the circuits.

Fast continuity testing offers a user-selectable test current of 20 mA or 200 mA.  Continuity testing covers 0.01Ω to 1MΩ without the need for manual range switching. 

The unit provides DC and Trms AC voltage measurements up to 600V.  It offers plenty of onboard test result storage and Bluetooth downloading capability. 

Rechargeable options for AC and charging are available. 

With a safety rating of CAT IV 600 V, the MIT485/2TC-LG2 features a redesigned case, back-stand, and 6 cell battery compartment with separate fuse access.  The instrument is over-moulded for increased protection and achieves an IP54 weatherproof rating.
