The MFT-X1 introduces our first generation of platform based, user upgradeable MFTs, to add to the existing Megger MFT1700 range of multifunction testers. It has been designed and manufactured at our Dover factory in the UK, incorporating a host of new features based on years of customer input. With the MFT-X1, we now offer True Loop™, our industry leading loop impedance test with patented Confidence Meter™ technology, full CertSuite Installation compatibility - to make certificate generation a breeze - high resolution loop testing, stabilised insulation voltage output, full colour screen and new operator interface are now standard. The user upgradeable operating software ensures the MFT-X1 has the ability to adapt to regulation changes and make it the perfect instrument for fast, reliable, accurate and adaptable testing.

Intended for use on all low voltage electrical installations including EV charge points and domestic photo-voltaic systems, the range of test capabilities allow for general commissioning of installations and periodic maintenance as well as detailed fault diagnostics.

MFT-X1 Firmware

MFT-X1 Firmware update

To update your instrument operating system:

The update process installs the new OS from a microSD card. It is important to use a blank microSD card for this purpose.

The microSD card MUST be removed from the instrument after the update has been completed, or the instrument will try to install the update each time it is switched on.

NOTE: Minimum recommended microSD card size is 4 GB and the maximum card size is 32 GB.

NOTE: The card must be formatted to the FAT32 format.

Download the latest operating system onto microSD card

1. Download the file from the link below.

2. Locate the MFT-X1 update ZIP file.

3. Unzip this file to your microSD card. It contains the instructions for updating the operating system and the required xxx.BIN file.

7. Fit the microSD card with the .BIN file into the microSD slot. (See user guide for guidance)

8. Replace the fuse cover and battery.

9. Switch the MFT-X1 to any range. The display will acknowledge the .BIN file is present.
