NOTE: ”Man 5 I
∆n ” and “AUTO” test modes aren’t available for RCD type A 500mA.
At the end of the test if
all six tests resulted to
be positive, the
instrument displays the
screen alongside
relative to the last
measurement effected.

Press the
START/STOP key once. The instrument carries out the
test injecting a current in phase with positive half wave of the
voltage indicated on
display by 0°.
Press the
START/STOP key once. The instrument carries out the
test injecting a current in phase with negative half wave of the
voltage indicated on
display by 180°.
The instrument generates a leakage current growing step by step
for a given time interval.
At the end of the test if the RCD tripping
current is
≤ I
∆n
(Type AC) or 1.4I

(Type
A with I ∆n > 10mA) or 2I ∆n (Type A with

double sound signal indicating the
positive outcome of the test and
displays the screen alongside.
