Particularly:
Non-editable field. It indicates the input that is configuring. The
INp UT
character "_A" or "_B" is added in case of a channel with 2 in-
puts (ex: 1_A, 1_B)
: the acquisition interval "personalized" for the channel
A CQUISITION
Field editable from the user. Name to assign to the sensor. This
Id e NTIfICA TION
field is exported as the heading of the column containing the
measurements of sensor in file .CSV type "Measurements"
Field editable from the user. Description ascribable to the sensor
d e SCrIp TION
for a better identification. This field is present only in file .CSV
type "log measurements"
M
Type of measurements to read on this input.
e A SUre Ty p e
Power supply (output voltage or current) that the NI2400 will
p Ow e r SUp p Ly
supply to the connected sensor. In case it is present "external",
the NI2400 doesn't supply any power supply Different power
supplies are proposed according to the "TYPE OF MEASUR-
MENT" selected.
UNIT
Electrical unit of measure of the sensor. For some types of sen-
M e A SUre
sors it is possible to choose between different units of measure
(ex for vibrating wire: digit, Hz, µs).
- [ ]
Field editable from the user. "Warm-up" time of the sensor. It
w A rM Up Se C
indicates how long the sensor is powered by the NI2400 before
starting the measurement cycle. For some types of measure-
ments, this field could be disabled.
This field allows to select which conversion to realize between
CONve rSION
LINEAR and POLYNOMIAL. It is also possible to decide to realize
NO conversion (in this case the reading is expressed in electrical
unit). This field is necessary to convert the reading of the sensor
from electrical unit (mA, mV, digit, etc.) to engineering unit (kPa,
mm, mbar, etc.)
This field is enabled if the linear conversion has been selected.

nomial Conversion Quick Start"
This field is enabled if the linear conversion has been selected.

This field is enabled if the polynomial conversion has been se-
b C d
lected. For further information, please refer to manual "Linear
and Polynomial Conversion Quick Start"
Field editable from the user. This field is enabled if the linear or
polynomial conversion is selected. It represents the acronym of
the unit of measure of the reading after the conversion in engi-
neering unit.
This field is enabled only for the type of measurement "Vibrating
Wire" or "Vibrating Wire + Thermistor". It indicates (in msec) the
period of each stimulation phase
This field is enabled only for the type of measurement "Vibrating
Wire" and "Vibrating Wire + Thermistor". It indicates (in msec)
the stabilization period, i.e. how long the NI2400 waits before
starting the reading phase
This field allows to set up the range of functioning of the sensor.
If AUTORANGE is configured, the NI2400 decides automatically
with which range it is going to do the measurement. This implies
an increase in the reading time of the sensor.
This field is enabled only for the type of measurement "Vibrating
Wire" or "Vibrating Wire + Thermistor". It indicates the frequen-
cy of the research start.
This field is enabled only for the type of measurement "Vibrating
Wire" or "Vibrating Wire + Thermistor". It indicates the frequen-
cy of the research end.
Amplification factor applied to sensors' signal. Raise this param-
eter only if sensor is placed far from datalogger and datalogger
provides unexpected or wrong readings.
(%)
Maximum amplitude of sensor excitation signal. Lower this pa-
rameter only if sensor is placed close to datalogger and provides
unexpected or wrong readings.
This parameter sets adapting speed of excitation signal during
vibraing wire reading.
Number of decimals recorded for this channel
The Data logger does not read the channel, but CSV file will be
populated with "skipped" values. This is to ensure compatibility
with software population layer in case of sensor change/removal.
