Service, Repair and Maintenance 410 and 430
Telecommunication Testing MIT Models: 480, 481 and 485
Special Applications Testing MIT Model: 40X
For Service, Repair and Maintenance:
The wide range of features makes the MIT420 ideal for maintenance technicians and engineers. Functions such as PI and DAR, capacitance measurement and a higher insulation range increase the suitability for applications such as:
Plant maintenance and production testing
Railway and other transportation maintenance and testing
Cable inspection/quality control
Street lighting maintenance
Avionics ground testing and maintenance
Military hardware and facility maintenance
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 MΩ 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 GΩ 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
