Use the switch located on
the bottom of the device (see
chapter “Components”) to
enter programming mode.
With the NanOMeter, it is
possible to interact with the
device using the three buttons
on the front. The upper and
lower buttons scroll through
the screens on the tab (if the
tab made up of several screens,
an arrow icon will appear on
the right corner of the screen)
while with the central key it is
possible to scroll through the
tabs (always viewable in the
The loading screen for programming
mode appears automatically once the
switch is activated.
In the rst tab it is pos-
sible to check the CT
connection status for the
individual phases. The
example shows the three
possible connection sta-
tuses. The rst status,
in green, conrms the
correct connection. The
second, in red, alerts of
an incorrect connection
order (you need to rever-
se the direction of the CT)
and the third, in yellow,
corresponds to an inde-
terminate connection sta-
tus (CT not connected or
load on the line is absent).
In the second tab you
can set the size of the CT
supplied to the meter. To
change the values, hold
down the central key of
the keypad (the editable
values are highlighted in
yellow with the selected
one ashing) and adjust
the values to the desi-
red numbers using the
scroll buttons. Press and
hold again to conrm the
change.
In this screen it is possible to program the device address on the BUS.
In the event an error occurs while attempting to save the address, an
“error” message will appear in red.Tthe green message “saved” will
conrm the operation completed successfully.
On the second page of the tab shown above, the phase sequence
is indicated. The rst example demonstrates that the order of the
voltage connections correspond to the order of the phases. In the
event that the phases are not ordered correctly, the second example
on the screen will appear, while the third example indicates an
indeterminate connection status.

CONNECTION AND LOAD CHECK
Once the programming procedure is complete, check the connection of the NanOMeter and the related CTs. A properly functioning system should show
all cosφ> 0.95 and an equitable load distribution over the three phases. Old electrical systems may have accumulated changes over time which can lead
to a recoding of cosφ> 0.85 which is still admissible, any recordings below this threshold indicate a probable wiring error.
CT CONNECTION TEST
It often happens that the connection of the phases is reversed in the electrical panels. If you notice power factors below 0.85 (even on a single phase)
it is possible that this happened.
In addition to verifying the correct connection of the CTs with the respective inputs of the NanOMeter, the following test must be performed:
If the potential difference has a value of 230Vac or 400Vac, it means that they correspond and that the connections of the power supply and the NanO-
Meter must be changed.
Caution: always check the consistency of the measured data (for example, the general line is greater than the other loads) and the settings of the CT
conversion factors are correct.
