6. If possible, disconnect all loads connected downstream
of the measured point, as the impedance of these users
could distort the test results. Perform the preliminary
calibration of the test leads as described in § 6.4.2
Connect the alligator clips or the remote lead to the
electrical mains according to Fig. 18, Fig. 19, Fig. 20
and Fig. 22 in the farthest possible point respect the
protection on test.
Note the presence of the correct voltage values
between L-N and L-PE corresponding to the selections
carried out in the initial phase (see § 5.1.4) as shown in
the screen to the side.
7. Press the
GO/STOP
key
for few seconds
or the
START
key on the remote lead. During this whole
stage, do not disconnect the measuring leads of the
instrument from the system under test.
In case of positive result (calculated minimum short-
circuit current HIGHER than tripping current of the
protection device within the specified time – see §
13.6), the screen to the side is displayed by the
instrument
Press the
SAVE
button or touch the
icon to save
the measurement (see § 7.1).
8. In case of negative result (calculated minimum short-
circuit current LOWER than tripping current of the
protection device within the specified time – see §
13.6), the screen to the side is displayed by the
instrument
Press the
SAVE
button or touch the
icon to save
the measurement (see § 7.1).
