Measurement of RCD trip timeConducting testing of rated residual non-operating currents at × 1/2 Range, measuring RCD trip time at × 1 and × 5 Ranges. • Measurement of trip out currentMeasuring trip out current by varying current automatically. • Remote TestEnabling a user to hold the Test Leads with his both hands by locking the Test Button. Measurement will automatically start when the main voltage is detected. • Voltage MeasurementCarrying out a constant measurement of voltage in the stand-by mode at each Range.
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
Accurate digital readout of tripping time. • Two neon lamps give quick check for correct wiring. • Compact, lightweight and simple to operate. • Zero cross circuitry permits testing at 0 and 180 degree portion of sine wave. At these two tests minimum (best) and maximum (worst) trip times will be displayed.
