Description Offers Technical Info Reviews

The Di-LOG ALVA MFT Pro is the flagship model in the ALVA range. Built to BS EN 61557 standards and packed with next-generation automation, it delivers advanced diagnostics, EV-ready capabilities, and data management.

A high-contrast full-colour TFT display with interactive pass/fail settings delivers instant feedback. Built-in fuse tables display maximum permitted Zs values on-screen, while intelligent 2/3 wire high-current loop detection and Automated Continuity & Earth Loop Auto Start minimises user input without compromising accuracy.

The RCD-LOC+ Xpert Loop Technology delivers high-accuracy, low-current Earth Loop measurements with adjustable test currents. RCD testing covers AC, A, B, B+, EV, F, and 6mA RDC-PD/MD types, with 1A RCD testing, and an automated EV Auto Test Sequence.

The 15mA continuity testing assesses inductive loads, while Zmax and Imax tracking capture worst-case loop impedance and fault current values. The ALVA MFT Pro also supports 3- and 4-pole Earth Resistance Testing using an optional accessory kit. It's 1,000-test internal memory permits data storage, traceability, and report integration.

Discover the full Di-Log ALVA range: the ALVA MFT Multifunction Installation Tester, and the ALVA MFT EV Multifunction Installation Tester Kit , and the ALVA MFT Pro EV Multifunction Installation Tester Kit .
