The new Megger range of insulation resistance testers are targeted at high end users, such as utility companies, equipment manufacturers and industrial electrical contractors and engineers.
Built around the same design as the rest of the Megger 5kV, 10kV and 15kV insulation resistance testers, the Megger MIT515 offers professional insulation resistance testing with up to 5kV test voltages and a maximum resistance of up to 10 TΩ. Offering a standard insulation resistance (IR) test as well as polarisation index (PI) and dielectric absorption ratio (DAR), the Megger MIT515 is the no-fuss entry level 5kV insulation tester offering the most cost effective solution in the new range of Megger's high voltage insulation testers.
With Megger's MIT515 the user can select from a fixed test voltage of 250V, 500V, 1000V, 2500V or 5000V or alternatively program a voltage from 100V to 5000V in 10V steps upto 1000V and 25V steps from 1kV to 5kV.
Megger have prioritised productivity and efficiency with the new MIT range of testers and all meters offer rapid charge Li-Ion batteries, which enable >60 minutes testing after a 30 minute charge. Li-Ion batteries also offer an advantage over Ni-MH (nickel metal hydride) batteries, as they generally provide higher power levels but also provide superior longevity in most cases.
With a safety rating of CAT IV 600V on all terminals and suitably rated 5kV test leads, the Megger MIT515 is built with operator safety and efficiency as the cornerstone of it's design. Just like the entire MIT series, the MIT515 is built around a dual case design, which includes a tough outer case to protect the tester from drops and knocks and an inner fire retardant case for added protection. With the case closed, the Megger MIT515 has an IP65 rating, preventing moisture and dust ingress.
An intuitive user interface ensures no lost time remembering how to use the tester. Simplicity of operation is achieved with two rotary switches and the large backlight display which enables multiple results to be displayed simultaneously. A graphical quick start guide is provided inside the lid to assist first time users. Five preset voltage ranges are provided in insulation test mode. Preconfigured diagnostic tests include Polarisation Index (PI), and Dielectric Absorption Ratio (DAR). The MIT515 does not benefit from an onboard memory and cannot save test results, unlike the other instruments in the MIT range, but it does offer a lower cost entry into the range of Megger's 5kV insulation testers.
