Di-Log ALVA MFT Installation Multifunction Tester

The Di-Log ALVA MFT Installation Multifunction Tester gives electricians a clear way to test new and existing circuits. It supports work on domestic, commercial and industrial sites. It also helps with full 18th Edition checks and BS EN 61557 testing.

This tester combines loop, RCD, continuity, insulation and EV charger test functions in one unit. As a result, users can move through common jobs with fewer separate tools. Its colour TFT screen shows results in a clear format, with pass and fail settings to support fast checks.

Smart Test Workflow

Auto-start loop and continuity testing helps speed up repeat tasks. Intelligent 2-wire and 3-wire loop detection also reduces manual set-up. Therefore, the Di-Log ALVA MFT Installation Multifunction Tester can help cut errors during busy test work.

RCD-LOC+ Xpert loop technology gives non-trip loop testing with a low-current earth loop method. The adjustable test current helps improve accuracy based on the RCD current. This is useful when testing protected circuits where safe, stable results matter.

EV and RCD Test Support

For EV work, the tester supports 6 mA RDC-PD/MD verification and EV charger diagnostics. It also covers RCD types AC, A, B, B+, EV, F and selective time delayed devices. These functions make it suitable for modern installation and fault finding tasks.

A hard shell case, leads, probes and calibration certificate are included for immediate use. In addition, the Di-Log ALVA MFT Installation Multifunction Tester includes on-screen help to guide test lead set-up. Manufacturer part code ALVAMFT is supplied for ordering and product records.
