HT ITALIA M75 Multitest True-RMS AC DMM & LAN Tester

HT ITALIA LOGO

Multifunction TRMS DMM for voltage AC/DC, Current AC, Frequency, Resistance measurements, Safety test on electrical plants and Wire mapping Test on LAN cables.

MULTITEST model M75 is an innovative instrument which joins together DMM, Safety Tester and LAN Checker features inside a compact and ergonomic user-friendly structure and with an extremely reduced weight (800g only).

The True RMS DMM is a professional instrument with True RMS measurement of AC/DC Voltage, AC/DC 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 current detection.

The Safety Tester features allow to perform test on electrical plants according to VDE0413. Continuity, insulation, global earth resistance, RCD’s, phase sequence indication and phase coincidence using only one test lead – by just touching cables, even insulated – or two test leads. The innovative AUTO function permits to perform automatically the main safety tests on a plant (namely earth resistance, RCD’s, insulation) by just connecting the instrument to a socket and pressing the START button, with a final response of OK or NOT OK.

LAN Checker detection of correct or incorrect wire mapping of a LAN cable with extremely simple indications about the errors found, to guide you step by step through the troubleshooting.
