MIT485 Same as Model 481, plus Bluetooth® download

MIT40X 10 V to 100 V in 1 V steps



Model applications

These models include all the features required for electricians, technicians and engineers working in a range of industries. Available features are selected to make testing easy and fast in a range of situations.



Building/Campus electrical maintenance

Large and small scale electrical installations

Periodic electrical systems inspection and testing

Cable testing



For Service, Repair and Maintenance:

The MIT430 adds additional features required for technicians and engineers working on more demanding applications. PI and DAR functions, capacitance measurement and a higher insulation range increase the suitability for applications such as:



Plant maintenance and production testing

Panelboard testing

Railway and other transportation maintenance and testing

Motor testing

Cable inspection/quality control

Street lighting maintenance

Avionics ground testing and maintenance

Military hardware and facility maintenance



Other model applications

Megger Testers are used to test electrical wiring and other components in buildings, manufacturing facilities, government entities and other general business operations.

Applications for these instruments include insulation testing, ground testing, low resistance testing, battery testing, hi-pot testing and more. With the broadest, most diverse choice of instruments in the industry, we are truly your single source for electrical testing needs.



Industrial and Power Electrical Installation MIT Models:400 410 and 420

Service, Repair and Maintenance 410 and 420

Telecommunication Testing MIT Models: 480, 481 and 485

Special Applications Testing MIT Model: 40X





Features and benefits:



CAT IV 600 V rating – provides greater safety when testing at higher voltage levels

Adjustable insulation test voltages – provides 250 V to 1000 V or 50 V to 1000 V. The special applications instrument (Model MIT40X) offers test voltages from 10 V to 100 V in 1 V steps.

Dual digital display readout – allows display of complimentary test information simultaneously (for example: M½ plus test voltage or MO plus leakage current)

Digital and analog arc display – includes not only the digital readout but also Megger’s patented analog arc to replicate the response of a moving coil display

Exceptional measurement range from 20 GO to 200 G½ - highest insulation test range available on the market, providing a superior range of measurement applications.

Choice of 20 mA or 200 mA continuity testing – allows user to select lower continuity range thus increasing battery life considerably

Continuity auto-test capability – enables real twohanded operation without the need to press the test button

Adjustable continuity limit alarm – allows pass/fail limits to be sent to speed testing

Automatically perform PI and DAR tests – user is able to quickly perform two important diagnostic tests. . . Polarization Index (PI) and Dielectric Absorption Ratio (DAR)

True RMS voltage measurement – allows accurate voltage measurement on noisy lines

Auto ranging voltage measurement – automatically adjusts range from millivolts to 600 V AC or DC, eliminating the need to keep changing ranging

Live circuit warning – automatically warns of contact to a live circuit, voltage is displayed and testing is inhibited

Auto fuse warning – warns of fuse failure automatically. No need to test the fuse manually.

Buzzer select button – enable or disable buzzer as required with resistance also displayed on the screen
