Selecting the above makes available the relevant
units of measure for “pressure”.
Choose the unit of measure from the list
available in the “Recording unit” selector.
Sentinel 2 and the PressView website
both require the Recording unit to be “m”
for correct operation.
Select “m”.
The appropriate scaling factors
(multiplier and offset) are also required.
Offset is usually “0”.
For Sentinel 2, calibration factors for
internal pressure transducers are applied
in production, such that it each digit
change represents a decimetre of
pressure (1/10 of a metre).
Or, put another way, the number obtained when the interface is read has to be
multiplied by 0.1 to convert it to metres (m, the selected recording unit).
“Input multiplier” is therefore set “0.1”.
The
“Logging Mode” should be set at “average” for
Sentinel 2; this will smooth-out any
noise (short fluctuations) in the readings and give a representative value of pressure.
When completed, click on “Accept” to update the configuration
being stored the IDT-PC
“current program” memory.
The channel settings are summarised in the
“Logging Channels” panel.
Note: External pressure sensors supplied by HWM for use with Sentinel 2 will behave
similarly once the calibration factors supplied on the label of the transducer
cable have been applied. (i.e. They will measure in decimetres and require an
Input multiplie
r of “0.1” when converting to metres).
Other pressure channels can similarly be checked or set up by first clicking the relevant
setup icon.
