Offering CAT IV, the Megger MIT515 is the simplest of Megger's range of small, light HV insulation resistance testers for the 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.

The MIT515 Insulation resistance tester (IRT) is primarily controlled by two rotary switches and a TEST button used to start and stop a test. The central rotary switch includes an ‘OFF’ position; the instrument switches on by rotating the switch either clockwise or anticlockwise from this position. A range of test voltages for insulation resistance tests up to 5 kV. The ‘lockable’ test voltage range can be adjusted in the settings function.

The settings function is indicated by a spanner symbol and facilitates lock voltage, low resistance alarm, temperature, time/date adjustment. A light blue coloured section of the rotary switch denotes memory functions; open records, download via USB and delete records.

A voltmeter is incorporated in the instrument and measures AC/DC voltage from 30 V to 660 V. Frequency (Hz) is measured and displayed for AC voltages. Voltmeter mode is activated by switching to ‘V’ mode.

Now equipped with lithium ion fast rechargeable batteries, the instrument 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.Care must be taken when replacing the MIT 515 rechargable battery

The Megger MIT515, MIT525 and MIT1025 can be powered from the mains supply or by it’s rechargeable battery, which provides for 4½ to 6 hours of continuous testing with a 100 MΩ load, depending on model. The battery pack contains Lithium-ion cells and should be replaced when it no longer holds a charge. A new battery is available as a spare part from Megger. The battery pack is housed within a grey moulded cover secured by four screws. On no account must the transparent inner case be opened. Hazardous voltages up to 5kV will be exposed.
