3. Voltage Measurement
When the instrument is first connected to the system, it will display the line-earth
voltage which is updated every 1s. If this voltage is not normal or as expected, DO NOT
PROCEED.
NOTE: This is a single phase (230V AC) instrument and under no circumstances should
it be connected to 2- phases or a voltage exceeding 230VAC+10%.
If the input voltage is greater than 260V the display will indicate '>260V' and RCD
measurements can not be made even if the Test button is pressed.
10.3.2 RCD Measurement
a) Single Tests
1. Press the Test button
Operating time of RCD is displayed on LCD. (At Ramp test, operating current value of
RCD will be displayed. Uc values are displayed at Uc Function.)
●
×1/2...................The Breaker should not trip.
● ×1......................The Breaker should trip.
● ×5......................The Breaker should trip.
● Auto Ramp(◢)..The Breaker should trip. The tripping current should be displayed.
● Uc......................Uc values are displayed.
2. Press the 0° /180° switch to change the phase and repeat step (1).
3. Change the phase again and repeat step (1).
b) Auto Test
Measurements are automatically performed under the Auto Test function in the following
sequence: X1/2(0° ), X1/2(180° ), X1(0° ),X1 (180° ), X5(0° ), X5(180° ).
1. Press F1 to select Auto
2. Press F2 & F3 to select IΔn & RCD type
3. Press the Test button. The KEW6016 will automatically conduct the sequence as
above. When the RCD trips each time reset it.
4. Return to the tester and the results will be displayed
● Be sure to return the tested RCD to the original condition after the test.
● When the Uc voltage rises to UL value or greater, the measurement is automatically
suspended and "Uc > UL" is displayed on the LCD.
● If " IΔn" setting is greater than the rated residual current of the RCD, the RCD will
trip and "no" may be displayed on LCD.
● If a voltage exists between the protective conductor and earth, it may influence the
measurements.
● If a voltage exists between neutral and earth, it may influence the measurements,
