Custom microprocessor controlled for highest accuracy and reliability. • 3 LEDs for checking correct wiring status. • 0 and 180 degree phase angle switch permits quick tests and consistent readings. • Digital read-out of tripping time. • Constant current source circuitry ensures that a fluctuating mains voltage does not affect the accuracy of readings. • Large custom digital display readout. • Visual indication of reversed phase and neutral wiring at socket. • Designed to IP54 Rating. • Complies with IEC 61557

Continuity Measurement Continuous testing can be carried out by use of the test button lockdown feature. A selectable buzzer gives instantaneous indication of continuity. Null facility eliminates the test lead resistance from the results, the nulled value is retained even if the instrument is switched off. Live circuit warnings are given by a flashing LED, buzzer and indication on the display. Insulation Measurement Three selectable test voltages 250V, 500V and 1000V. An auto-discharge function ensures that circuits are not hazardous after testing. A red LED gives warning of high voltage output during testing and discharging of the circuit. In case of connecting to a live circuit, a live circuit warning is given by flashing LED, buzzer and indication on the display. Loop Impedance Measurement A patented (ATT) low current loop impedance test enables high accuracy loop measurements and quick testing without tripping RCD's. A high current alternative is selectable for even higher accuracy and instantaneous results. The subsequent test will default to the low current test, this saves any inadvertent tripping of the RCD.
