Key Features:

The MI 3155 EurotestXD is the newest flagship of Metrel’s most advanced line of multi-functional measuring instruments and is designed specifically for testing in industry. What differentiates this instrument from the rest is its ergonomic design and an intuitive user interface, encompassing a memory organizer and fully programmable AUTO SEQUENCEs, managed through a large colour touch screen display. It is fully compliant with functionality standards (e.g. IEC/EN 61557) and other reference standards for testing (e.g. IEC/EN/HD 60364-4-41,...) as is required for any instrument that performs TRMS current measurements, RCD tests, line and loop impedance tests with 3 (and 4) wires and earth resistance measurements. Besides those, the instrument supports a wide range of tests and measuring functions, including on-line voltage monitoring, phase sequence testing, varistor testing, PI/DAR calculation, luminance measurement, discharge time testing, ISFL measurements, IMD tests as well as functional and visual inspections.

• Programmable AUTO SEQUENCEs. *

• Predefined profile dependent AUTO SEQUENCEs.

• Predefined Automatic tests:
    Auto TT (U, Zln, Zs, Uc);
    Auto TN/RCD (U, Zln, Zs, Rpe);
    Auto TN (U, Zln, Zlpe, Rpe);
    Auto IT (U, Zln, Isc, Isfl, IMD).

• Functional inspections.

• Visual inspections.

• Custom inspections (visual and functional) which may be 

  incorporated into AUTO SEQUENCEs.

• EVSE AUTO SEQUENCEs and function inspections;

• Machine functional and visual inspections;

• Built-in help screens for referencing on site.
