Specification

• Custom microprocessor controlled for highest accuracy and reliability.
• 3 LEDs for checking correct wiring status.
• 15mA LOOP measurement:
LOOP impedance 2000© 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). (4118A only)
• Safe voltage measurement function.
• Large custom digital display readout on all models.
• Measure low loop resistances(resolution of 0.01©)
• 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
