Specification Notes
  • Insulation resistance accuracy changes with the selected test voltage and resistance range. At 500 V, 250 V and 100 V, readings above the respective stated thresholds have an accuracy of ±10%.
  • Three-wire non-trip loop testing uses the Confidence Meter™ and requires an L-N loop resistance below 12 Ω. The function is intended for circuits protected by an RCD rated at 30 mA or greater.
  • The CAT III 600 V / CAT IV 300 V safety rating is valid up to an altitude of 2000 m. The safety rating applies with respect to earth.

Frequently Asked Questions
What is the Megger MFT-X0 Multifunction Tester used for?

The Megger MFT-X0 Multifunction Tester is designed for testing, inspecting and maintaining low voltage electrical installations. It supports voltage measurement, continuity testing, insulation resistance testing, loop impedance measurement and RCD testing. It is suitable for domestic, commercial and industrial electrical installations, including EV charge points and domestic solar PV systems.

Does the Megger MFT-X0 support non-trip loop testing?

Yes. The Megger MFT-X0 supports both 2-wire and 3-wire non-trip loop impedance testing. Its True Loop™ technology and patented Confidence Meter™ help provide stable, repeatable readings, even where electrical noise is present. Three-wire non-trip testing is designed for circuits protected by RCDs rated at 30 mA or greater.

What is the Megger Confidence Meter™?

The patented Confidence Meter™ displays the progress of loop impedance measurements and indicates the presence of electrical noise on the circuit. It helps reduce the effect of unwanted readings and supports consistent test results. On quiet circuits, non-trip loop tests typically take around seven seconds.

Can the Megger MFT-X0 test different types of RCD?

Yes. The Megger MFT-X0 supports Type AC, A, B, AC(S), A(S) and B(S) RCD testing. Users can select individual tests or create custom automatic test sequences, including ramp testing. This flexibility helps simplify RCD inspection and testing.

What insulation test voltages does the Megger MFT-X0 offer?

The Megger MFT-X0 provides insulation test voltages from 50 V DC to 1000 V DC, including variable settings from 50 V to 999 V. Its stabilised output voltage is controlled to -0% to +2% +2 V at rated load or less. This provides accurate test voltage control and helps reduce the risk of over-voltage damage to sensitive components.

Can the Megger MFT-X0 transfer test results to a mobile device?

Yes. The Megger MFT-X0 uses Bluetooth® Low Energy to transfer test results to compatible Android and iOS devices running Megger CertSuite Installation software. Results can be linked to circuit information and synchronised with the cloud-based application. CertSuite Installation also supports electrical certification, reporting and remote access for authorised users.

Does the Megger MFT-X0 have an upgradeable operating system?

Yes. The Megger MFT-X0 features a user-upgradeable operating system. Firmware updates can be installed by downloading the latest .BIN file from Megger onto a suitable microSD card. Once the card is inserted into the instrument, pressing TEST starts the automatic update process.

What type of batteries does the Megger MFT-X0 use?

The Megger MFT-X0 is supplied with an AA alkaline battery adaptor and eight LR6 (AA) alkaline batteries. An optional 7.2 V DC, 4400 mAh rechargeable Li-ion battery pack is also available. The rechargeable pack provides more than 15 hours of operation based on typical daily testing, with a charging time of approximately 2.5 to 3 hours.

Is the Megger MFT-X0 suitable for outdoor use?

Yes. The Megger MFT-X0 has an IP54-rated housing that protects against dust ingress and water splashes, making it suitable for indoor and outdoor use. It operates in temperatures from -10°C to +55°C and is supplied with a rugged, weather-proof carry case for protection and storage.

What safety rating does the Megger MFT-X0 have?

The Megger MFT-X0 has a CAT III 600 V / CAT IV 300 V safety rating, valid at altitudes up to 2000 metres. It also includes active live voltage protection to 600 V between test terminals and live earth detection. If the PE terminal is live when a loop or RCD test range is selected, the instrument indicates the condition and inhibits the test.

What is included with the Megger MFT-X0 Multifunction Tester?

The Megger MFT-X0 is supplied with an AA alkaline battery adaptor, eight LR6 (AA) alkaline batteries, a complete set of test leads and a rugged, weather-proof carry case. A rechargeable Li-ion battery pack is available as an optional accessory.

Can the Megger MFT-X0 be used for electrical certification?

Yes. The Megger MFT-X0 works with Megger CertSuite Installation software to support electrical certification and reporting. Test results can be transferred from the instrument to a compatible mobile device, linked to circuit details and synchronised with the cloud. CertSuite Installation is available through monthly or annual subscription packages.
