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.FEATURESTrue 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 technologyAll 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.MFT-X1 result downloading and CertSuiteTest results can be tagged with circuit data and transferred to CertSuite, the latest cloud base electrical certification software package from Megger.When paired to a mobile device using the low energy Bluetooth® mode, results can be sent directly from the MFT-X1 to an Android or IOS device running Megger CertSuite software. These results are also synchronised with the cloud-based application.With a wide range of certification options, CertSuite is available as a monthly or yearly subscription package for electrical certification of installations taking results directly from the MFT whilst testing. CertSuite is suitable for multiple concurrent users and is optimised for use with the MFT-X1.Results can be stored and reviewed remotely by users whilst on site from different locations, accessed by head office or other users with the relevant permission, with professional looking certification and reports. True Loop™ test with patented Confidence Meter™ CertSuite™ compatible Bluetooth® result transfer Next generation 2-wire and 3-wire non-trip loop testing User upgradeable operating system High resolution 0.001Ω loop test Automatic volt-drop measurement Stabilised insulation test voltage Configurable RCD and EV auto-sequence tests Fast switch rechargeable plug-in battery pack Full colour TFT bonded display Re-designed lead set and carry case solution IP54 operational housing
High resolution loop impedance testingThe MFT-X1 has extended the low end of the loop impedance range from 0.01 ohms to 0.001 ohms resolution and 50 kA current calculation. The True Loop impedance measurement using the patented confidence meter makes these low impedance measurements a realistic option, with two wire test connections and high current testing.RCD custom testingRCD testing can now be optimised with the RCD test configurator. Select a whole suite of tests or only those elements of the RCD you require. You can even add ramp testing to the sequence, optimising and simplifying testing.EV Charge point testingSuitable 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 voltageFor the first time in any multifunction tester, the MFT-X1 incorporates a stabilised insulation test voltage, ensuring output voltage is accurate to within +/-3% +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 measurementThe 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. *Optional accessoryCustomer upgradeable operating systemThe operating system of the MFT-X1 range is upgradable by the user, simply by downloading the latest operating system file (.BIN) from the Megger web site to a suitable microSD card.Insert the updated microSD card and pressing TEST initiates an automatic update process without the need for further user intervention.Display and user interfaceThe 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.Li-ION Battery solutionThe Megger MFT-X1 can be powered by either the Megger Li-ION battery pack or using standard NiMH or Alkaline batteries. The unique 4 Ahr rechargeable Li-ION battery can be swapped with the AA carrier module, providing the fastest and most flexible battery change solution in the industry. APPLICATIONS The primary application is the testing of low voltage electrical installations in domestic, commercial, and industrial installations for single and three phase systems.The wide range of test capabilities extend the use of the MFT-X1 to include: EV charge point testing Domestic PV testing Motor/Generator testing Machine testing Portable appliance safety testing Panel building and switchgear manufacturing Cable testingGraphical assistanceThe instrument has context help to provide graphical circuit connection guidance for each of the measurements.AccessoriesThe 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.MFT-X1Multifunction testerwww.megger.com 2
