1. Press the
MENU
key, move the cursor to
V%
in the
main menu by means of the arrow keys (
,
) and
confirm with
ENTER
. Subsequently, the instrument
displays a screen similar to the one reported here to the
side.

2. Use the
,
keys to select the parameter to be modified, and the
,
keys to
modify the parameter value:
MODE
this virtual key allows setting the test mode. The following options are
available:
L-N, L-L, CAL
.
Inom
this virtual key allows setting the
value of rated current of protection
device in the
range
1A
to
999A
in steps of
1A
.
Lim
this virtual key allows setting the
maximum allowed limit value of voltage
drop (
V%
) for the mains being tested.
Z>
<
this position allows performing the first
Z1(Offset)
impedance
measurement. In this case, the instrument will measure the zeroed impedance
upstream of the initial point of the mains being tested, taking it as a starting
reference.
3. Select the
CAL
mode by means of the arrow keys
,
and perform the calibration of
the
test cables or of the cable with mains plug by using the
ZEROLOOP
accessory
before performing the test
(see § 6.7.2).
4. Connect the instrument to the initial point of the mains being tested (typically
downstream of a protection device) according to Fig. 33 or Fig. 34 in order to carry
out the first
Z1 (Offset)
impedance measurement. In this case, the instrument will
measure the impedance upstream of the initial point of the mains being tested, taking
it as starting reference. The following screen (referred to L-L measurement) appears
on the display.
5. Use the
,
keys and move the cursor to the “
Z>

”
position. Press the
GO/STOP
key on the instrument to
start the test. The following screen is shown on the
display.
