just from this Harmonic, goes on increasing the
index.

H) SOCKET FOR EXTERNAL DC FEEDER

A socket has been added for external feeder with
output 6 VDC (+4% -35%), 150 mA, 0.15 A.

F) AUTOSCROLL MANAGEMENT

During activation of the measures LOG(storage),
the Autoscroll of the harmonic displayed, when
enabled, increases the harmonic index at each
recording cycle.  The frequency of the increment
thus coincides with the “LOG_RATE” and enables
the recording of all 24 Harmonics consecutively.
In the 3 pages displaying the Harmonics the status
of the SCROLL enabled and commanded by the
LOG function is shown by turning on MEM in the
display.

G) MODBUS COMMAND FOR SETTING A

DETERMINED HARMONIC

The NANOVIP PLUS includes a Modbus command
that allows you to set the immediate calculation of
a determined harmonic.
The Modbus command to be sent is the following:

:01060279 Hn 00 Crc CR LF

where :

: =

start of Modbus string

01=

default address of NANOVIP PLUS

06 =

write command

0279 = Harmonic address
Hn =

value from 0 to 24 to set Harmonic desired

00 =

value not managed by NANOVIP PLUS used
only to complete the Modbus string

Crc =

check-sum

CR =

carriage-return

LF =

line-feed

Note that this type of operation remains valid only
when autoscrolling of the Harmonics is disabled.
If this is not the case, the Modbus command sets
the Harmonic desired, but the autoscrolling, starting
