Change Change status [YES, NO]
YES: The instrument measures leakage current in two sequential steps
with delay* in between. The phase voltage is firstly applied to the
right live output of the mains test socket and secondly to the left
live output of the mains test socket.
NO: The phase voltage is applied only to the right live output of the
mains test socket.
