DESCRIPTION
The Megger MIT400 Series insulation and continuity testers
has been designed for electrical testing by power utilities,
industrials, telecommunication companies, commercial/
domestic electricians and anyone with unique test voltage
requirements. 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
MIT410 50 V, 100 V, 250 V, 500 V and 1000 V plus PI
and DAR
MIT420 Same as Model 410 plus result storage
MIT430 Same as Model 420 plus Bluetooth® download
MIT480 50 V, 100 V
MIT481 50 V, 100 V, 250 V, 500 V, 1000 V plus PI, DAR and
result storage
MIT485 Same as Model 481, plus Bluetooth® download
MIT40X 10 V to 100 V in 1 V steps
Panelboard testing is faster, easier and safer with the new MIT400 Series.
APPLICATIONS
MIT Models 400, 410, 420 and 430
Industrial and Power Electrical Installation Testing:
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. Typical applications
include:
n
Building/Campus electrical maintenance
n
Large and small scale electrical installations
n
Periodic electrical systems inspection and testing
n
Cable testing
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
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:
n
Commercial avionics testing
n
Military land, marine and air communications testing
n
Manufacturing/production line testing
n
Electrostatic test and measurement
n
Component testing
n
Battery powered traction and lifting equipment testing

FEATURES AND BENEFITS
n
CAT IV 600 V rating – provides greater safety when testing
at higher voltage levels
n
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.
n
Dual digital display readout – allows display of
complimentary test information simultaneously
(for example: MΩ plus test voltage or MΩ plus
leakage current)
n
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
n
Exceptional measurement range from 20 GΩ to 200 GΩ
- highest insulation test range available on the market,
providing a superior range of measurement applications.
n
Choice of 20 mA or 200 mA continuity testing – allows
user to select lower continuity range thus increasing
battery life considerably
n
Continuity auto-test capability – enables real two-handed
operation without the need to press the test button
n
Adjustable continuity limit alarm – allows pass/fail limits to
be sent to speed testing
n
Automatically perform PI and DAR tests – user is able
to quickly perform two important diagnostic tests. . .
Polarization Index (PI) and Dielectric Absorption Ratio
(DAR)
n
True RMS voltage measurement – allows accurate voltage
measurement on noisy lines
n
Auto ranging voltage measurement – automatically adjusts
range from millivolts to 600 V AC or DC, eliminating the
need to keep changing ranging
n
Live circuit warning – automatically warns of contact to a
live circuit, voltage is displayed and testing is inhibited
n
Auto fuse warning – warns of fuse failure automatically.
No need to test the fuse manually.
n
Buzzer select button – enable or disable buzzer as required
with resistance also displayed on the screen
