MFT-X1 Multifunction tester 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 Patented Confidence meter technology The MFT-X1 new electrical installation testing platform MFT-X1 is the first of a new generation of firmware upgradeable, full functionality multi-function testers for low voltage electrical installations. 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. 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 result downloading and CertSuite FEATURES 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. Test 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

MFT-X1 Multifunction tester High resolution loop impedance testing The 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 testing RCD 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...
