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.
