Parameters

nscan

The number of readings in a single scan.

zeroPos

The position of the zero reading within the scan

readingsPos

The position of the readings to be zeroed within the scan.

nReadings

The number of readings immediately following the zero reading that are sampled at the same gain as the

within a scan, the size of the scan, and the number of readings to zero. However, this function does
not do the actual conversion. A non-zero return value indicates an invalid parameter error.
