The wide range of features also makes the MIT400 Series ideal for maintenance technicians and engineers. They replace the well-established BM400 insulation tester range, giving greater functionality with simplified operation, greater application range and increased safety. The range The range consists of eight instruments: MIT400 250 V, 500 V and 1000 V Panelboard testing is faster, easier and safer with the new MIT400 Series. MIT410 50 V, 100 V, 250 V, 500 V and 1000 V plus PI and DAR APPLICATIONS MIT420 Same as Model 410 plus result storage MIT Models 400, 410, 420 and 430 MIT430 Same as Model 420 plus Bluetooth download Industrial and Power Electrical Installation Testing: MIT480 50 V, 100 V These models include all the features required for electricians, technicians and engineers working in a range MIT481 50 V, 100 V, 250 V, 500 V, 1000 V plus PI, DAR and of industries. Available features are selected to make testing result storage easy and fast in a range of situations. Typical applications MIT485 Same as Model 481, plus Bluetooth download include: n Building/Campus electrical maintenance MIT40X 10 V to 100 V in 1 V steps n Large and small scale electrical installations n Periodic electrical systems inspection and testing n Cable testing MIT400 Series CAT IV Insulation Resistance and Continuity Testers Service, Repair and Maintenance: The MIT Models 410, 420 and 430 add additional features required for technicians and engineers working on more demanding applications. Functions such as PI and DAR, capacitance measurement and a higher insulation range increase the suitability for applications such as: n Plant maintenance and production testing n Panelboard testing n Railway and other transportation maintenance and testing n Motor testing n Cable inspection/quality control n Street lighting maintenance n Avionics ground testing and maintenance n Military hardware and facility maintenance MIT40X shown measuring electrostatic charge in a computer control room. MIT Models 480, 481 and 485 Telecommunication Testing FEATURES AND BENEFITS Designed to cope with the additional requirements of the n CAT IV 600 V rating provides greater safety when testing telecommunications industry, MIT Models 480, 481 and 485 at higher voltage levels include 50 V and 100 V range insulation testing as standard, n Adjustable insulation test voltages provides 250 V to 1000 plus higher voltages as required.
