The Megger MIT410-TC3 insulation resistance and continuity testers have been designed specifically for use within the telecommunications industry. Unique telecommunications-related features include a soft canvas carrying bag with shoulder strap and rugged snap hook to attach to a tool belt, and a “bed of nails” test lead set.

By applying a test voltage, (for customer premise wiring or telecommunications cables, a voltage level of no more than 500 volts is recommended), the meters will measure the leakage current through the insulation and give the results in ohms. The results can then be reviewed to determine if the premise wire or cable pair can be used for voice grade or voice/video/data services according to the following industry standards:

• Readings greater than 100 Megohms indicate good insulation.
• Readings between 100 Megohms and 90 Megohms indicate marginal insulation (services may or may not work).
• Readings below 90 Megohms indicate bad insulation and further testing is required before service can be installed.

In addition to the insulation resistance test, the meters allow the technician to conduct continuity tests throughout the customer’s premise. Simply place a shunt strap at the location of the modem, then with the meter go to each outlet to test for continuity using the audible alert feature on the meter to determine correct wiring configurations. This feature would replace the need for a tone generator and amplifier
