True Loop™ Testing with Confidence Meter™

Loop impedance testing is one of the most important functions for electrical installation testing, and the MFT-X1 includes Megger True Loop™ technology as standard.

True Loop™ uses Megger's patented Confidence Meter™ to help provide stable, repeatable loop impedance results, even on difficult or electrically noisy supplies.

The Confidence Meter™ shows the progress of the loop measurement and helps filter out circuit noise, reducing the risk of unstable or misleading readings.

This is particularly useful when testing close to the source of supply, working on noisy installations, or carrying out non-trip loop testing on RCD-protected circuits.

High Resolution Loop Impedance Testing

The Megger MFT-X1 extends the low end of loop impedance testing down to 0.001Ω resolution, helping electricians carry out more detailed measurements where low impedance values matter.

The MFT-X1 also supports 50kA current calculation, making it suitable for more advanced installation testing and fault-level assessment.

With 2-wire test connections, high current testing and True Loop™ measurement technology, the MFT-X1 provides a practical solution for contractors who need accurate loop impedance testing across a wide range of electrical installations.

EV Charger Testing with the Megger MFT-X1

The Megger MFT-X1 is suitable for EV charge point installation testing and maintenance when used with the Megger EVCA adaptor.

It can support testing on EV charger installations with either Type B RCD protection or RDC-protected charge points, helping electricians verify safety and compliance on modern EV charging installations.

EV-specific testing capability is especially important for contractors working across domestic, commercial and workplace EV charging projects, where RCD, RDC and loop testing requirements need to be handled accurately.

Configurable RCD Testing

The MFT-X1 includes configurable RCD test sequences, allowing electricians to select the specific RCD tests required for the installation.

Users can choose a full suite of tests or only the elements needed for the job, including ramp testing where required.

The MFT-X1 supports a wide range of RCD testing requirements, including:

• Type AC RCD testing
• Type A RCD testing
• Type B RCD testing
• Selective RCD testing
• Ramp testing
• 6mA RDC testing for EV applications

This helps reduce unnecessary testing steps while still supporting thorough electrical verification.

CertSuite Installation and Bluetooth® Result Transfer

The Megger MFT-X1 can transfer test results to Megger CertSuite Installation using low energy Bluetooth® connectivity.

Results can be tagged with circuit data and sent directly to an Android or iOS device running Megger CertSuite software.

Once transferred, results can be synchronised with the cloud-based CertSuite application, helping contractors streamline certificate creation, reporting and job records.

This is particularly useful for teams who want to reduce manual data entry, improve reporting consistency and make test results available to office-based staff or other authorised users.

Stabilised Insulation Test Voltage

The Megger MFT-X1 includes stabilised insulation test voltage designed to deliver more accurate test voltage control during insulation resistance testing.

Megger states that the MFT-X1 output voltage is accurate to within -0% +2% +2V at rated load or less, helping reduce the risk of over-voltage stress on sensitive circuits and components.

This makes the MFT-X1 a strong option for contractors working on modern installations where electronic devices, sensitive equipment and complex circuits are increasingly common.

Display, Interface and On-Site Usability

The Megger MFT-X1 uses a full colour TFT bonded display with a high contrast screen and a monochrome black-on-white mode for difficult lighting conditions.

The colour-coded rotary dial is mirrored on the instrument screen, making range selection easier when working in poor lighting or challenging environments.

Hot keys for second-level functions are displayed on-screen, and the second control dial allows quick selection of highlighted features, even when wearing protective gloves.

The display can show useful information before and after testing, including the Confidence Meter™ progress bar, RCD ramp test progress, insulation and continuity bar graphs, and the voltage widget showing L-N, L-E and N-E voltages.

Battery, Carry Case and Site Protection

The Megger MFT-X1 is powered by a rechargeable Li-ion battery pack, with an optional AA alkaline adaptor available separately.

The fast-switch rechargeable battery design is intended to support flexible on-site working, while the IP54 operational housing helps protect the instrument during everyday use.

The tester is supplied in a rugged weather-proof carry case, along with a lead set designed for the different connection challenges found in modern electrical systems.
