LOOP / PSC Tester 4116A/4118A   • 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). (4118A only) • 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 IEC61557 Front Cover MODEL 4116A 4118A Loop Impedance Ranges 20/200/2000Ω 20/200/2000Ω Loop Impedance Accuracy |±2%rdg±4dgt |±2%rdg±4dgt AC Test Current 20Ω 25A 200Ω 2.3A 2000Ω 15mA 20Ω 25A 200Ω 2.3A 2000Ω 15mA AC Test Period 20Ω (20ms) 200Ω (40ms) 2000Ω (280ms) 20Ω (20ms) 200Ω (40ms) 2000Ω (280ms) PSC Ranges ----------- 200A(2.3A 40ms) 2000A(25A 20ms) 20kA(25A 20ms) PSC Ranges Accuracy ----------- Consider accuracy of Loop impedance Voltage 110V-260V ±2%rdg±4dgt Operating Voltage 230V+10% -15%(195V~253V)50Hz Safety Standard IEC61010-1 CAT.III 300V IEC61557-1,-3 IEC61010-2-031 Pollution Degree 2 IP Rating IEC60529-IP54 Dimensions 185(L) × 167(W) × 89(D)mm Weight 750g approx.
