RCD tester. Measuring device that tests the properties of a residual current device (RCD). Specifically, it measures the contact voltage, the switch-off time and the switch-off current for residual current devices of types A, AC, S and recently also the mixed frequency type F. Digital display, colored backlit OLED displayLED for measuring point illuminationPatented fixation of the measuring tipsCompact and robust - for rough service operations and laboratory operation. Testing residual current devices (RCD circuit breakers)Measuring the contact voltage without triggering the switch. The contact voltage related to the nominal residual current is measured at 1/3 of the nominal residual current.Tripping test with nominal residual current, measurement of the tripping timeSpecial tests of systems or RCD circuit breakersTesting of systems or RCD protective circuits with increasing residual current with display of the tripping currentTesting of RCD circuit breakers IN = 10, 30, 100, 300 and 500 mATesting of RCD circuit breakers with 1/2 N, 1 N, 2 N, 5 N up to 100 mA nominal current)Testing of RCD circuit breakers with half-waves (pulsating direct current) to determine the tripping time and the tripping currentTesting of special RCD circuit breakersselective S, type AC, type AMeasuring mains voltage and fault loop impedance. 1 test device with mobile measuring tip including 4 batteries (AAA) 1 bag 1 short operating instructions 1 CD-ROM with operating instructions in the available languages 1 factory calibration certificate
