MIT515, MIT525, MIT1025, MIT1525 5 kV, 10 kV, 15 kV DC Insulation Resistance Testers ■ Measures up to 30 Tfi ■ Safety rated up to CAT IV 1000 V to 3000 m ■ Unique dual-case design - additional user protection ■ Operates from battery or a.c. mains supply ■ Rapid charge Li-ion battery ■ Advanced memory with time / date stamp ■ Transit case DESCRIPTION Megger's new range of d.c. insulation testers, MIT515, MIT525, MIT1025 and MIT1 525 are targeted at original equipment manufacturers and industrial companies. The top of the range MIT1525 performs insulation resistance tests up to 15 kV with a 30 TO maximum resistance and an accuracy of ±5 % from 1 MO up to 3 TO. The MIT515 offers IR, DAR and PI functions but has no memory functionality. MIT525, MIT1025 and MIT1 525 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 a.c. source if the batteries are flat. Rapid charge batteries enable > 60 minutes testing after a 30 minute charge. ■ MIT515: 5 kV IRT with PI and DAR but no memory ■ MIT525: 5 kV IRT with all test modes including a ramp test plus advanced memory functions with recall to screen, RTC for time/date stamp of results and USB cable interface to PC / PowerDB ■ MIT1025: 10 kV IRT with all test modes including a ramp test plus advanced memory functions with recall to screen, RTC for time/date stamp of results and USB cable interface to PC / PowerDB ■ MIT1525: 15 kV IRT with all test modes including a ramp test plus advanced memory functions with recall to screen, RTC for time/date stamp of results and USB cable interface to PC / PowerDB Safety rating is not compromised on the MIT range with all terminals safety rated to CAT IV 600 V to 3000 m (5 kV, 10 kV) or CAT IV 1000 V to 3000 m (15 kV). A range of 5 kV and 10 kV test leads are available plus dedicated 15 kV test leads, which are double insulated with clips designed for 15 kV creepage paths. The 15 kV leads are supplied in a holdall. 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 IP65 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 shown 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. Test leads are double insulated (0) with clamps rated at 3 kV (0) equivalent to 6 kV single insulation for the medium clip leadset and 5 kV (0), equivalent to 10 kV single insulation for the large clip. The 15 kV leadset is insulated to 15 kV. Advanced memory storage includes time/date stamping of results, logging of data and recall of results to screen. A fully isolated USB device interface (type B) is used for safe transfer of data to Megger's PowerDB / Pro, Advanced and Lite asset management software. (MIT525, MIT1025 nd MIT1525 only) Optional transport case For an additional cost the instrument can be supplied in a high quality transport case which has enough storage space to store two standard lead sets, fused test leads for voltage measurements and a set of screened test leads. The new transport case keeps the users required test leads together with the instrument, especially useful when instruments are stored

MIT515, MIT525, MIT1025, MIT1525 5 kV, 10 kV, 15 kV DC Insulation Resistance Testers LARGE INSULATED TEST CLIP 3 M X 3 LEADSET These test leads are supplied as standard on MIT1025 and MIT1525 models (different leadset dependant on model). These clips are designed for clamping on to larger diameter test pieces. The insulation is designed only to protect the user from the output of Megger 5 kV, 10 kV and 15 kV insulation resistance testers. The clips cannot in any circumstance be relied on to protect the user from live a.c. systems above 600 V a.c., r.m.s. in an CAT IV environment. PRACTICAL...
