True Loop™
True Loop™ impedance testing is now a standard feature on the MFT-X1. The latest 3-wire non-trip loop testing technology, incorporated with the patented Confidence Meter™, offers an unmatched, reliable, accurate, stable and repeatable loop test solution to the user, allowing testing in the most hostile high noise conditions or close to the source of supply. The technology also removes the risk of RCD uplift whilst reducing typical test times – even on circuits protected by 6 mA or 10 mA protective devices.
Patented Confidence Meter™ technology
All loop impedance ranges are now supported by the Megger patented Confidence Meter™ technology, reducing typical test times for non-trip loop testing to around 7 seconds on quiet circuits, and providing optimised test times for loop impedance testing in difficult noisy supplies. The Confidence Meter™ shows the progress of the loop measurement and indicates the
presence of noise on the circuit, removing erroneous values to give a stable and consistent result.
CertSuite™ compatibility
The MFT-X1 is the first fully integrated instrument for use on the CertSuite™ software platform. Test results can be tagged in the instrument and transferred directly to any test certificate or report open on an IOS® or Android® mobile device running the CertSuite™ App. Professional certificates and reports can be completed on-site by multiple users with the confidence the data is protected by the cloud-based application*.
*CertSuite is available on a monthly or yearly subscription.
High resolution loop impedance testing
The MFT-X1 now includes a high resolution, high current, 2-wire loop impedance test that, with the integration of the Confidence Meter™, provides accurate measurements down to 0.001Ω resolution, with PFC/ PSCC current calculation up to 50 kA.
RCD configurator
RCD testing can now be optimised with the RCD configurator, allowing the user to select only those elements of an RCD test required to be completed in the auto-RCD test mode.
EV Charge point testing
Suitable for both EV charger installation testing with either RCD Type B or RDC protected charge points. The MFT-X1 in conjunction with the Megger EVCA adaptor can test all known EV chargers for installation or maintenance.
Stabilised insulation test voltage
For the first time in any multifunction tester, the MFT-X1 incorporates a stabilised insulation test voltage, ensuring output voltage is accurate to within +2% +2 digits. This compares to the industry standard of +20% and so provides a more accurate test voltage without the risk of over-voltage damage to circuits or sensitive components.
Current measurement
The MFT-X1 uses current clamps for current measurement using the optional Megger MCC1010 current clamp for measurement of AC currents from 1 mA to 1000 A.
Operating system upgrades
A user upgradable operating system - using a standard microSD card - helps future-proofing the MFT-X1 against changing regulations or testing requirements.
Display and user interface
The user interface utilises the flexibility of the high contrast 480 x 272 colour, TFT bonded display, with a monochrome black on white mode designed specifically for use in difficult lighting conditions. Enhancing the colour coded test selection rotary dial, range selection is now replicated on the instrument screen, ensuring easy use in poor lighting environments. Hot keys for second level functions are clearly shown across the top of each screen and the second control dial provides users with a further quick selection option of any highlighted feature, even if wearing protective gloves. Relevant information is clearly shown on the display, both before and after each test, in full colour, and includes the Confidence Meter™ progress bar, RCD ramp test progress as well as the insulation and continuity measurement bar graph. The new Voltage Widget, displays the L-N, L-E and N-E voltages.
Always on with Modula battery technology
The Megger MFT-X1 can be used with either the Megger Li-ION battery pack, or the AA NiMH or Alkaline battery technologies*. The unique battery pack solution enables the rechargeable 4 Ahr Li-ION pack to be swapped with the AA carrier module, providing the most flexible and fastest battery change solution in the industry. A smart fuel tank chip technology optimises battery status accuracy on the Li-ION pack.

Graphical assistance
The instrument has context help to provide graphical circuit connection guidance for each of the measurements.
Accessories
The MFT-X1 is shipped in a rugged, weather-proof carry case offering outstanding protection and flexible storage. Also included is a complete set of test leads to meet the wide range of connection challenges in modern electrical systems.
