Detailed Description

Designed for accuracy and ease of use, the ALVA MFT features a vivid full-colour TFT display with interactive controls, allowing users to set pass/fail conditions effortlessly. It supports a full range of RCD types, including AC, A, B, B+, EV and F, making it a versatile solution for modern electrical installations.

The ALVA MFT Installation Multifunction Tester simplifies testing with automated Continuity & Earth Loop Auto Start, accompanied by a secondary display for recorded results. Its intelligent 2/3 wire high-current loop detection eliminates the need for manual selection, automatically identifying whether a 2-wire or 3-wire Loop/PSCC measurement is being conducted.

Di-LOG ALVA MFT Multifunction Tester Key Features

  • Full-Colour TFT Display: High-contrast screen with interactive pass/fail settings for intuitive operation.
  • Fully Automated: Continuity & Earth Loop Auto Start with secondary display for recorded results.
  • Intelligent 2/3 Wire High-Current Loop Detection: Automatically identifies 2-wire or 3-wire Loop/PSCC measurement, eliminating manual selection errors.
  • Dynamic Non-Trip Loop: RCD-LOC+, our latest Xpert Loop Technology delivers high-accuracy, low-current Earth Loop with an adjustable test current feature to optimise the test accuracy based on your RCD current.
  • Full Range RCD Type: required for fault finding supporting – AC, A, B, B+, 6mA EV and F
  • Variable RDC Test: allows users to set custom mA values when required.
  • Insulation Test with Bargraph: with selectable voltages of 50V, 100V, 250V, 500V & 1000V with adjustable pass/fail values
  • 3-Phase: Line-Line Impedance with dynamic phase rotation indication.
  • Rechargeable Capability (Optional Kit Required): The ALVA MFT includes an inbuilt charging facility when used with the optional NiMH battery and charge lead kit, allowing convenient charging and longer operation without regular battery changes.
  • On-screen Help: a visual aid to assist test lead configuration and instruction

For enhanced customisation, the variable RDC test feature enables users to dial in bespoke mA values, ensuring greater flexibility across different testing scenarios. The ALVA MFT also includes 6mA RDC-PD/MD testing, allowing electricians to safely and accurately verify the performance of EVSE chargers as part of electric vehicle infrastructure installations.

Additionally, the ALVA MFT is equipped with inbuilt fuse tables, which indicate the maximum permitted Zs Loop values when carrying out Earth Loop Impedance testing—helping electricians maintain compliance with industry safety standards.

Whether working on domestic, commercial, or industrial installations, this state-of-the-art tester delivers outstanding value and uncompromising accuracy. Designed for compliance, efficiency, and reliability, the ALVA MFT is the ultimate solution for professionals seeking affordable next-generation electrical testing.

Upgrade your testing experience with the Di-LOG ALVA MFT—precision, reliability, and compliance in one powerful device.
