Measurement of RCD trip time Conducting testing of rated residual non-operating currents at 1/2 Range, measuring RCD trip time at 1 and 5 Ranges. Measurement of trip out current Measuring trip out current by varying current automatically. Remote Test Enabling 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 Measurement Carrying out a constant measurement of voltage in the stand-by mode at each Range. Auto-detection of Contact voltage Detecting the voltage to earth of Earth electrodes or Protective conductors during RCD test - when applying test currents - at measurement using EARTH in order to prevent electrical shocks caused by the damaged earth. Measurement will be ceased at AC50V or more. Dust- and Water-proof Dust- and Water-proof construction (designed to IEC 60529 IP54). Backlight Facilitating working at dimly illuminated locations. mohon cek stock sebelum order, terima kasih wa 081291419751
