6. If possible, disconnect all loads connected downstream
of the measured point, as the impedance of these users
could distort the test results. Connect the alligator clips
or the remote lead to the electrical mains according to
Fig. 16, Fig. 17, Fig. 18 and Fig. 20 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 § 5.1.3) as shown in
the screen to the side.
7. Press the GO/STOP key 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 §
12.6), 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 §
12.6), 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).
