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:

MIT Models 480, 481 and 485
Telecommunication Testing
Designed to cope with the additional requirements of the
telecommunications industry, MIT Models 480, 481 and 485
include 50 V and 100 V range insulation testing as standard,
plus higher voltages as required.
In addition, the voltage detection test inhibit feature has been
raised to 75 V (from 50 V), to allow testing of cables with
coactivity coupled induced voltages, which would normally
inhibit such testing with a 50 V protected instrument.
Finally the MIT481 and MIT485 models include measurement
of cable distance by capacitance, providing a convenient
cable length without the need to use TDR technology, with
adjustable cable capacitance from 40 nF/Km to 60 nF/Km
(default is 50 nF/Km).
MIT Model 40X
Special Applications Testing
The MIT40X provides a new solution for unique
insulation voltage measurement requirements. The MIT40X
has a variable insulation test voltage from 10 V to 100 V
in 1 V steps, selectable in the “Set-Up” menu.
Typical applications include:

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: MΩ 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 GΩ
- 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 two-handed
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
