Command ‘C’— Sub-command Index 01: Collect Data for a Calibration Point
This sub-command has two (2) additional required parameters.
Command “C 01 pnt pppp.pppp”
‘C’ is the command letter.
‘ 01’ is the sub-command index (ii) for Collect Data
‘ pnt’ identifies a particular calibration point that will be supplied. It
must be between 1 and npts, where npts was a parameter of the previously
executed Configure & Start (‘00’) sub-command.
‘ pppp.pppp’ is the pressure value (in current EU) that is actually applied
currently to the module’s transducers by a precision calibrator.
NOTE: all parameters are separated by a space.
Response “pppp.pppp [pppp.pppp]...”
The actual measured pressure values (in current EU) from each affected
channel of the module (highest numbered specified channel first, lowest
numbered specified channel last, as per the pppp bit map parameter of the
Configure & Start (‘00’) sub-command. The decimal response datum
format (format 0) is always used.
Description: This sub-command (to be executed two or more times) carries out the data
collection phase of the Multi-Point Calibration function for exactly one (1)
calibration point (i.e., per parameter pnt). Each execution applies a specified
pressure value; then collects, averages, and stores the data for that calibration point.
It must be repeated until all pressure points, as specified by the npts parameter of the
original Configure & Start (‘00’) sub-command, are applied and their data collected.
For each particular point, enter the sub-command after that point’s pressure value
has been properly applied to the module, and that value is stable (unchanging).
Pressure may be applied to either the Cal or Run ports, as necessary. Use a Model
903x Calibrator or some other suitable precision pressure source to generate the
pressure.
