M75 is an innovative instrument which joins together DMM, Safety Tester and LAN checker inside a compact and ergonomic user-friendly structure and with a extremely reduced weight (800g only!).
The DMM is a professional instrument with TRMS measurement of AC/DC voltage, AC Current (through external clamp), Resistance and Frequency. Additional features are MAX/MIN/AVG function, HOLD function and PEAK detection with Response Time of 1ms, useful for surge currents detection.
The Safety Tester features allow to perform test on electrical plants according to VDE0413. Measures of Continuity, Insulation, Global Earth value (also with 0.1 resolution), RCDs test, phase sequence indication and phase coincidence (using only one Test Lead even just touching even insulated cables or two Test Leads) will be easily performed thanks to this new extremely compact instrument. An innovative function (AUTOTEST) automatically performs main safety checks in the plant (Earth Resistance measurement, RCD Test, Insulation Test) just connecting the instrument to a socket and pressing the GO button. The instrument will give you a final response (OK or NOT OK) about the safety of the plant under test.
Finally the LAN checker function allows you to check if the wire mapping in a LAN cable is correct or not with easy indications about the found errors, which will guide you though the troubleshooting. M75 is completed by a modern selector function knob, a large numeric display for easy readings of measurements and a protection rubber holder to prevent accidental damaged.
