Chi tiết



Custom microprocessor controlled for highest accuracy and reliability.
3 LEDs for checking correct wiring status.
15mA LOOP measurement:
LOOP impedance 2000Ω range measurement is carried out with low test current (15mA).
The current will not cause tripping out involved RCD even the one with the lowest nominal differential current (30mA).
Direct reading of Prospective Short Circuit Current (PSC).
Safe voltage measurement function.
Large custom digital display readout on all models.
Measure low loop resistances(resolution of 0.01Ω)
Automatic lock-out if test resister overheats.
Large custom digital display readout .
Visual indication of reversed phase and neutral wiring at socket.
Designed to IP54 Rating
Complies with IEC 61557
