During the ramp test if the RCD trips
to separate the circuit at a tripping
current higher than I
∆n (Type AC) or 1.4
I ∆n (Type A with I ∆n >10mA) or 2 I ∆n
(Type A with I
∆n
≤10mA), the instrument
emits a long sound signal at the end
of the test and displays the values
alongside.

THIS RESULT CANNOT BE SAVED.
In order to store the contact voltage value U

(out of the limits) effect the test under U

mode.
Message "Att
UL": a too high
contact voltage
was detected.
ATTENTION: the RCD tripping current is higher
than the rated value of the set differential current
(I ∆N =30mA was set in the example ).
Maximum current generated by the instrument
during the test for general RCDs (the value
indicated is referred to an AC type 30mA RCD, in
this case the maximum current supplied is equal to
1.4xI
∆N )
Message “>50V” o “>25V”: the instrument detects
a contact voltage higher than the selected limit
(50V in this case).
