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 (
Z
L-PE
LOWER or EQUAL to
limit impedance relative to protection device within
the specified time
– see § 13.7), 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. (
Z
L-PE
HIGHER to limit impedance relative to
protection device within the specified time
– see §
13.7), 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. If the electrical Noise between N and PE conductors is
so high that it could compromise the result accuracy,
the symbol
is displayed. It’s recommended to
switch off all the electrical loads and re-attempt the
measurement
