The MIT515 5 kV insulation resistance tester is
a CAT IV rated, compact tester for the diagnostic testing and maintenance
of high voltage electrical equipment. Enclosed in a tough case, it is both
smaller and lighter than its predecessor making it even easier to carry and
store.
As well as measuring insulation resistance to 20 TΩ,
the MIT515 also offers various diagnostic tests such as polarisation index,
dielectric absorption ratio, step voltage, dielectric discharge, and ramp
testing.
The MIT515 is also equipped with lithium-ion fast
rechargeable batteries and has a large, clear, easy-to-read, display
making it equally suitable for use in both bright sunlight and poorly lit
environments. Information displayed includes resistance, voltage, leakage
current, capacitance, battery status, and time constant. In addition, the
elapsed time of the test is displayed constantly, removing the need for
separate timer.
