KEW 5410

  • 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.
