The new controllers MIT400 Insulation and continuity combine ergonomics for
intensive use and unmatched performance for the most demanding users.
The MIT400 series replaces the famous BM400 and BM80 with more extensive features and increased security.
Their compact and lightweight and compatibility handedness in fact an extremely popular product.
Consists of 8 instruments in 3 groups of applications:
Special Telecommunications Industrial Applications
MIT400 MIT480 MIT40X
The use of these instruments is simple and intuitive:
all functions are visible on the range selector and buttons below the display. No function
The display offers dual digital display and the famous fast and accurate analog bargraph Megger.
Test results are displayed in large characters.
The ancillary information such as frequency, leakage current, test voltage and residual voltage are displayed in smaller font.
The test voltage is selectable from 10 V to 1000 V depending on model, and adjustable from 10 V to 100 V on
MIT40X models dedicated to isolation measures directed TBT Telecomor specific.
The span of the insulation resistance is unsurpassed by 20 GW to 200 GW.
For demanding applications, the user chooses to display simultaneously the value of the actual test voltage
applied and that the leakage current.
The isolamètres for industrial applications to diagnose finely systems
insulation of rotating machinery through BT tests Polarization Index (PI) and absorption ratio
Dielectric (DAR). A timed test of isolation is also available and adjustable from 1 to 10 minutes.
To facilitate verification, the user can set a minimum insulation resistance below which the alarm beeps.
ADJUSTABLE VOLTAGE ISOLATION (MIT40X)
The MIT40X has an isolation test voltage programmable from 10 V to 100 V in steps of 1 V. The device is configured by the user to be fully compliant with the requirements of the application without having to return the factory.
A continuity test to 200 mA, according to the law, with a maximum resolution of 0.01, allows
a quick check of the resistance and continuity on all types of circuits and particularly on the ground conductors.
This test can be performed at 20 mA when compliance with rrules for electrical testing is not necessary,
significantly extend the life of batteries.
A snapshot of continuity beeper, adjustable according to the values required by the legislation in force, allows the rapid tests when there is no need to record measured values.
This beep can be disabled by the user for use in environments where discretion is required.
The test leads supplied with the MIT400 series are isolated in high quality silicone, which guarantees
measurement quality unmatched in the isolation resistance values higher and especially above 10 GW.
DOWNLOAD REGISTRATION & RESULTS
MIT420 and MIT481
The MIT420 and MIT481 store the test results and allow easy recall of the screen.
MIT430 and MIT485
The MIT430 and MIT485 store the test results and can transfer them to a PC using the supplied software Megger Download Manager.
Data transfer is done either via Bluetooth or USB. The interface
Bluetooth ensures total isolation between the PC and the instrument for the implementation of the transfer.
Category IV 600 V
All instruments of the MIT400 range are designed to comply with safety standards for
USENo Category IV 600 V.
(A) Maintenance and Service Testing Facilities
The MIT400, MIT410, MIT415, MIT420 and MIT430
include all the features and characteristics necessary for engineers and technicians working
particularly in the following industries:
Maintenance Organizations domestic and industrial control manufacturing test and production
Insulation monitoring and continuity
Manufacture of tables and boxes
Rail and other (B) Telecommunication Networks
Designed to meet the specific requirements of
the telecommunications industry, the MIT480 and MIT481 provide insulation test voltages of 50 V and 100 V.
Inhibiton test at 75 V
The inhibition threshold of the test on presence detection voltage can be raised to 75 V to allow tests on cables with voltages induced by coupling or noise.
Capacity and length
The MIT481 and MIT485 display cable length from the measurement of capacity of the cable tested.
(C) Special Applications
The range of MIT40X provides a unique solution for critical applications. They can adjust
the test voltage isolation between 10 V and 100 V.
Tensions are predefined 10 V, 55 V, 50 V, 65 V, 90 V, etc.. commonly used in applications such as:
Tests electronic components and boards
Measuring electrostatic manufacturing
