5. Move the slide bar reference by selecting the protection
tripping time between the options:
0.1s
,
0.2s
,
0.4s
,
1s,
5s.
Confirm the choice by going back to the initial
measurement screen.
Touch the “k Isc” field to set the calculation coefficient
of the short circuit current
Isc
. The following screen
appears on the display
6.
Touch the
icon to zero the value in the field and use
the virtual keyboard to set the calculation coefficient of
the short circuit current
Isc
within the values allowed by
the instrument
Confirm the choice by going back to the initial
measurement screen
7. 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 shuko plug, 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-L 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.
8. 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 (minimum short-circuit current
interrupted by the protection device within the time
indicated by 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).
9. In case of negative result (minimum short-circuit current
NOT interrupted by the protection device within the time
indicated by 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
icon to save
the measurement (see § 7.1).
