of the measured point, as the impedance of these users

could distort the test results. Connect the shuko plug,

the alligator clips or the remote lead to the electrical

mains according to Fig. 16, Fig. 17, Fig. 18 and Fig. 20.

Note the presence of the correct voltage values

between L-L 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

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

cable with the performed selections), 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 (three-phase Isc current for

the L-L case in the image NOT supported by the cable

with the performed selections), the screen to the side is

displayed by the instrument.

Note the presence of the measurement result

highlighted in red.

Press the SAVE button or touch the
