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.

Sleep Function
(1)

Automatically enters Sleep mode in 3 minutes after the last switch operation (current consumption 75µA). This function doesn't work at voltage measurements. To exit from the Sleep mode, set the Function switch to OFF position once, and re-set it to the Range at which a measurement to be conducted.

(2)

Backlight turns off in 1 minute after it lights up.
