KYORITSU 5410 - Manual (Page 6)

3. Feature
This instrument is a digital RCD Tester to measure the trip time and trip
out current of RCDs. It also equips the function to measure the voltage.
● Measurement of RCD trip time
Conducting testing of rated residual non-operating currents at x 1/2
Range, measuring RCD trip time at x1 and x5 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.
● 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 IEC60529 IP54)
● Backlight
Facilitating working at dimly illuminated locations.
