The npts parameter fixes how many calibration points must be supplied when the
Multi-Point Calibration function’s data collection phase starts later with multiple
invocations of another sub-command (described below). Currently, only a linear (1st
order) (‘ ord=1’) fit of the calibration points is available.
Example:
! Configure and start the Multi-Point Calibration function so that it affects only the
first four (4) channels of the module. Three (3) pressure calibration points will by
supplied when we continue this function later (see example for ‘01’ sub-command
below). A linear (1st order) fit will be used to obtain a new set of offset and gain
correction coefficients for these four (4) channels. The maximum average sample
count (32) is used to collect each calibration data point, so as to minimize any noise
in the data samples. The module’s data acquisition process is altered immediately
to collect the increased number of averages.
