Megger MFT-X0 Multifunction Tester

The MFT-X0-BS, Multifunction Tester BS1363 from manufacturer is a professional, firmware-upgradeable electrical installation tester engineered for fast, reliable commissioning, maintenance and fault-finding on low-voltage installations. Designed for electricians, contractors and test engineers working on domestic, commercial and light industrial installations — including EV charge points and photovoltaic systems — the MFT-X0 combines advanced loop-testing algorithms, stabilised insulation measurements and a flexible user interface in a rugged, IP54-rated housing. Compact and practical, it delivers repeatable, standards-compliant results while simplifying workflow with Bluetooth result transfer and cloud-compatible certification.

Benefits

• Faster, more reliable loop testing: The patented Confidence Meter™ and next-generation True Loop™ testing modes reduce test times and remove noisy or unstable readings, delivering accurate loop impedance measurements even in hostile supplies or close to supply sources.
• Improved accuracy and protection for sensitive equipment: Stabilised insulation test voltage guarantees output within -0% +2% +2 V of rated voltage, offering far tighter control than industry norms and reducing the risk of over-voltage damage to sensitive circuits.
• Streamlined reporting and traceability: Built-in Bluetooth Low Energy connectivity works with Megger CertSuite Installation to tag, send and synchronise test results to mobile devices and the cloud for on-site certification and multi-user access.
• Flexible, field-ready operation: A full-colour TFT bonded display with monochrome mode, graphical connection guidance and glove-friendly controls makes the instrument easy to use in poor lighting and on busy sites.
• Long runtime and fast battery swap: Use the standard AA battery module or the optional 4,400 mAh Li‑ion pack for extended testing sessions. The Li-ion pack delivers long battery life and rapid recharge for demanding daily use.
• Rugged, practical package: Supplied with a robust, weather-resistant carry case and a redesigned lead set, the MFT-X0 is IP54-rated and built to withstand real-world working conditions.

Key features

• True Loop™ with patented Confidence Meter™

- Advanced 2-wire and 3-wire non-trip loop testing modes (including high-current and high-resolution options) with a visible Confidence Meter™ progress indicator. Non-trip loop resolution to 0.01 Ω and support for measurements up to the full range of supply voltages and frequencies. Designed to deliver stable, repeatable loop impedance readings in noisy or difficult environments.

• CertSuite Installation compatible Bluetooth® result transfer

- Built-in Bluetooth Low Energy enables direct transfer of test results to Android and iOS devices running Megger CertSuite Installation, with cloud synchronisation for remote review, professional certificates and multi-user access. Tag circuit data on the instrument and export seamlessly to the CertSuite workflow for immediate documentation.

• Stabilised insulation test voltage and comprehensive insulation testing

- Stabilised output voltage accurate to -0% +2% +2 V at rated load for insulation tests from 100 V up to 1000 V (MFT-X0: 100 V–1000 V). High accuracy across ranges (0.001 MΩ to 999 MΩ auto-ranging), low leakage current measurement, and controlled short-circuit current to protect delicate components while delivering reliable, standards-compliant insulation readings.

• RCD custom testing and advanced ramp capability

- Supports Type AC, A, B and S variants (including AC(S), A(S), B(S)) with configurable auto-sequences, ½ IΔn no-trip, 1×, 2×, 5× IΔn trip tests and programmable ramp testing (10 mA–1000 mA). Accurate trip-time and trip-current measurement, fault (touch) voltage reporting and immunity to inductance effects in some RCDs through resistance-based measurement methods.

• User-upgradeable OS, intuitive display and flexible power options

- Firmware upgradeable via microSD for future feature additions and improvements. High-contrast 480 × 272 full-colour TFT bonded display with monochrome mode, context-sensitive graphical guidance and hot-key access for core functions. Power options include standard AA alkaline module or optional 7.2 V Li‑ion 4400 mAh pack (supplied with MFT-X1 variant), with long run times (>15 hours typical) and fast recharge—ideal for full-day site use.
