RCD Testers скачать игры для android поздравления мужчине с днем рождения 5410 • Measurement of RCD trip time • Measurement of trip out current • Remote Test • Voltage Measurement • Auto-detection of Contact voltage • Dust- and Water-proof • Backlight 5406A • 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 • Test of a large kind of RCD's: Standard, Selective, AC and A (DC sensitive breakers) 5402D • 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.
