HEAT INSULATION
Test result storage
Bluetooth® wireless data transfer
The new Megger MIT400 series insulation and continuity testers has been designed for electrical testing by the utilities, industrial, commercial and domestic electricians. The wide range of features also makes the MIT400 series ideal for the maintenance and service/repair engineer. They replace the well-established BM400 insulation tester range, given greater functionality with simplified
Insulation Testing
Test voltages - 250 V to 1000 V insulation test voltages available
Test Lock - Locks insulation test on continuously.
The actual test voltage is displayed on the smaller digital readout.
The insulation result on the larger digital display.
Analogue arc display to replicate the response of a moving coil display.
Polarisation Index (PI) and Dielectric Absorption Ratio (DAR) functions
Insulation testing from 10GΩ to 200GΩ
High quality flexible silicone test leads prevent measurement errors on higher GΩ ranges.
Test inhibit prevents testing if voltages in excess of 50 V are detected.
Insulation buzzer can be set to buzz if the insulation resistance is above a preset limit.
Continuity Testing
Auto test on circuit contact.
200mA or 20mA continuity test currents are available.
20 mA test current will considerably increase battery life.
Lead resistance compensation (NULL) operates up to 9 Ω of resistance.
Buzzer ON-OFF selected by simple push button.
Continuity buzzer limit alarm adjustable from 1 Ω to 20 Ω in 5 steps.
Analogue arc display
Full display width analogue arc.
Patented arc display shows charge and discharge characteristics not visible on a digital display.
Single pointer “needle” response is similar to a moving coil meter.
Logarithmic display for better low insulation value measurements.
Dual digital display
Large main digital readout for good visibility of all main measurement results
Second digital display for additional data such as: Insulation test voltage.; Insulation leakage current ; Supply frequency (when measuring volts). ; Test mode eg. PI, DAR or TI (Timed mode).
Storage & Downloading results
The MIT430 is capable of saving test results for recall to the screen. A simple storage structure allows for a test number and screen results to be recalled individually.
The MIT430 supports both test result storage and downloading. Test results can be stored in the instrument and subsequently downloaded to a computer with the Megger download manager software. Data transfer is by Bluetooth, with the transmitter being enabled when the Download mode is selected on the instrument. NOTE: The receiving PC needs to have Bluetooth capability or a USB port fitted a Bluetooth receiver. Class II (10m) is acceptable.
Safety
Designed to be exceptionally safe to use, fast detecting circuitry prevents damage to the instruments if accidentally connected to live circuits or across phases. Specifically, all instruments:
Meet the international requirements of IEC1010-2 and EN61557.
Live circuit detection inhibits insulation testing on circuits above 50 V.
Live circuit detection and test inhibit on continuity measurements.
Default display of live circuit voltage on all ranges.
Detection and inhibit functions even if the protection fuse has failed.
Suitable for use on CAT IV applications and supply voltages to 600 V.
