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
