Megger / Biddle MIT515 5 kV Insulation Resistance Tester

Megger / Biddle MIT515 5 kV Insulation Resistance Tester

The Megger MIT515 offers resistance testing up to 5 kV, with a maximum resistance of up to 10 TΩ, and standard insulation resistance (IR) testing, polarization index (PI), and dielectric absorption ratio (DAR).

The Megger MIT515 user can select test voltages of 250 V, 500 V, 1000 V, 2500 V, 5000 V, or programmable voltages from 100 V to 1 kV in 10 V steps, or 1000 V to 5000 V in 25 V steps.

MIT515 focuses on productivity and efficiency, offering rapid-charge Li-Ion batteries and operation from an AC source if the batteries are flat. Rapid-charge batteries enable> 60 minutes of testing after a 30-minute charge. Compared to Ni-MH (nickel metal hydride) batteries, Li-Ion batteries generally deliver higher power levels and, in most cases, superior longevity.

The Megger MIT515 is designed with operator safety and productivity as the cornerstone of its build. A CAT IV 600 V safety rating is maintained on the MIT515 for all terminals and test leads. The MIT515 has a dual-case design, featuring a tough outer case to protect the tester from knocks and drops and an inner fire-retardant case for added protection. The IP rating in a closed case is IP65, eliminating moisture and dust ingress.

An intuitive user interface ensures that no time is wasted remembering how to use the tester. Two rotary switches and the large backlight display enable multiple results to be displayed simultaneously. Inside the lid, the MIT515 provides a graphical quick start guide to assist first-time users.

Five preset voltage ranges are provided in insulation test mode, and a user-settable lock voltage range. Preconfigured diagnostic tests include the Dielectric Absorption Ratio (DAR) and the Polarization Index (PI). The MIT515 has no onboard memory and cannot save test results, but it does provide a lower-cost entry into Megger’s 5kV insulation tester range.
