The Metrel MI 3152 InstalTest IT-XC is an instrument from the new generation of Metrel’s multifunctional measuring instruments. The already well known functions like complete installation safety testing according to IEC/EN 61557 and Pre-Programmed AUTO SEQUENCE testing of TN, TT and IT earthing systems are managed by a completely new user interface based on large colour touch screen display. A wide range of functions is included: from on-line voltage monitoring, phase sequence testing, varistor testing, earth resistance measurement, illuminance measurement and TRMS current measurement up to RCD tests, line and loop impedance tests, specific earth resistance measurements as well as ISFL measurements and the IMD tests. The IT-XC is pre-set with AS/NZS3017 limits for pass/fail indication on tests.
