MIT515, MIT525, MIT1025, MIT1525 MIT515, MIT525, MIT1025, MIT1525 30 TΩ maximum resistance PI, DAR, DD, SV and ramp test Operate from battery or AC source Rapid charge Li-ion battery Safety rated CATIV V to 3000 m (1) Advanced memory with time/date stamp DESCRIPTION Megger s new range of DC insulation testers MIT515, MIT525, MIT1025 and MIT1525 are targeted at original equipment manufacturers and industrial companies. The top of the range MIT1525 performs insulation resistance tests up to 1 with a 30 TΩ maximum resistance and an accuracy of ±5 % from 1 MΩ up to 3 TΩ. The MIT515 offers IR, DAR and PI functions but has no memory functionality. MIT525, MIT1025 and MIT1525 have a full suite of test modes as well as on-board memory and the ability to stream data/download data to a PC/ laptop. Instrument productivity is a focus of the new MIT range which offers rapid charge batteries and operation from an AC source if the batteries are flat. Rapid charge batteries enable > 60 minutes testing after a 30 minute charge. Safety rating is not compromised on the MIT range with all terminals safety rated to CATIV 600 V to 3000 m (, 10 kv or CATIV V to 3000 m (1). A range of and 10 kv test leads are available plus dedicated 1 test leads which are double insulated with clips designed for 1 creepage paths. The 1 leads are supplied in a rucksack. Suitably rated HV gloves and other personal protection equipment are required to be worn when testing. The MIT range share dual case design which includes a tough outer case to protect the tester from knocks/drops and an inner fire retardant case. The IP rating is IP 65 case closed eliminating 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, plus a user settable lock voltage range. Preconfigured diagnostic tests include Polarisation Index (PI), Dielectric Absorption Ratio (DAR), dielectric discharge (DD), Stepped Voltage (SV) and ramp test. Advanced memory storage includes time/date stamping of results, logging of data and recall of results to screen. A fully isolated USB interface is used for safe transfer of data to Megger s asset management software; PowerDB Pro, Advanced and Lite packages. Test leads are double insulated t with clamps rated at 3 kv t equivalent to 6 kv single insulation for the medium clip leadset and t equivalent to 10 kv single insulation for the large clip. The 15kV leadset is insulated to 15kV.

MIT515, MIT525, MIT1025, MIT1525 APPLICATION The Insulation Resistance (IR) test is a quantitative test which indicates the effectiveness of a product s electrical insulation. Applications include cables, transformers, motors/generators, circuit breakers and bushings. Common insulation tests are the spot test, a 1 minute IR test and a 10 minute Polarisation Index (PI) test, where PI is the ratio R10min/R1min and temperature independent.

The MIT420 and MIT430 add capacitance (to 10uF), frequency (to 400Hz) and test result storage. MIT430 has Bluetooth for wireless data transfer and comes with Megger download software. All models include carrying case, test leads, battery. All models except the MIT400 also include a remote switch probe for hands free testing. MIT300 Series The new MIT300 Series features a large display and hands-free operation. The tough, rubber armored case is designed for rough handling and weatherproof to IP54. A rigid cover folds up to protect the front panel when not in use. Intelligent safety features include: MIT410 MIT310 Safety Interlock prevents unsafe connection of test leads Safe contact detectors the tester will remain safe and not be damaged if connected to a live circuit while on continuity setting. Live voltage warning alerts when circuit voltage is >25V. Safety lockout inhibits test when circuit voltage is >50V. Continuity check prevents a continuity test on a live circuit. Each model includes a 200mA continuity test function and continuity buzzer. All models except the MIT300 measure DCV & ACV (50/60Hz) to 600V. The MIT330 adds memory for storing test results and a USB interface. The MIT310A has an analog meter display for those who prefer a moving needle.
