The M74 is one of the four multifunction installation testers belonging to MULTITEST family of portable multifunction installation testers designed to perform Global Earth Resistance measurements, trip out time test on AC type RCDs, Insulation and Continuity of earth conductors according to VDE and IEC standards on civil electrical installations. Powerful AUTOTEST feature permits M74 to quickly perform an automatic sequence of the above tests directly to the plugs of electrical plants with OK or NOT OK response results. M74 multifunction installation tester also includes other features as phase sequence with 1 terminal, leakage current with optional transducer clamp and a powerful DMM function for TRMS measurements of voltage and current ideal for troubleshooting both in civil and industrial environments. Voltage and current peak measurement in 1ms is also useful for inrush current evaluation of electrical motor devices.
Like all models of MULTITEST family M74 has a large LCD display for easy readings, a modern and ergonomic external case, an innovative friendly-use electronic range selector as well as a protective rubber holder to prevent accidental damage.
