The Megger MIT480 series of instruments has been developed specifically for the telecommunications industry. The insulation and continuity testers combine the latest range
of measurement techniques with new instrument design to provide a state-of-the-art tester that is compact and comfortable to hold.
The MIT480 series directly replaces the well-established BM80 product group, given greater functionality with simplified operation and a wider range of applications.
The Range:
MIT480: 50V, 100V tester
MIT481: 50V, 100V, 250V, 500V, 1000V tester
MIT485: As MIT481 with additional download of results via Bluetooth
Full comparison can be found on the datasheet.
STORAGE AND DOWNLOADING RESULTS
MIT481
The MIT481 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.
MIT485
The MIT485 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 MIT485 Bluetooth transmitter being enabled when the Download mode is selected on the instrument.
NOTE: The receiving PC needs to have Bluetooth capability.
All quoted accuracies are at +20°C.
