• Kew Combitester provides the ultimate in Microprocessor technology offering Loop and RCD tests with a comprehensive memory and downloading test results.
• LOOP Impedance 200/2000© range measurement is carried out using a test current of 15mA. This current will not trip RCD’s rated at 30mA or greater.
• High resolution for low Loop Impedance (resolution of 0.01©) on 20© range.
• Direct reading of Prospective Short Circuit Current (PSC) and earth fault current.
• RCD tests at 0 and 180 degree phase angle switch permit quick tests and consistent readings.
• Test of a large kind of RCD's Standard, Selective, AC and A (DC sensitive breakers).
• Constant current source circuitry ensures that a fluctuating mains voltage does not affect the accuracy of readings.
• RCD Ramp test in order to indicate the actual tripping current of RCD.
• Contact Voltage Reading (UC). with two selectable contact voltage limits
(50 and 25V).
• Visual indication of correct wiring status and automatic lock-out if test resistors overheats.
• Designed to IEC 61010-1, IEC 61557 and high protection degree IP54.
• The stored data can be transferred to PC via Optical Adapter Model 8212-RS232C and 8212-USB.
