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
Anti-Trip Technology for complete trip free Loop testing on all RCDs rated 30mA and above. • Dual Display allows simultaneous measurements like Loop & PFC/PSC. • Two wire connection for Loop L-L, L-N and PSC testing is possible. • Phase rotation, Voltage and Frequency measurements. • Lock-down test button for 'hands free' testing with auto-start operation.
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.
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
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.
