8.6 Ramp test
The RCD trip current is measured by applying a test current of half the rated trip current and increasing this every
300 ms (or 500 ms for type S RCDs) from 30% to 110% of the RCD current rating. When the RCD trips, the current flowing is
recorded and displayed in mA.
Making a measurement
.1 Select the appropriate RCD rated current on the right hand rotary switch
= 30 mA etc.
.2 Select the RAMP test on the left hand range knob.
