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.
