8.1.4 Background calibration / autoadjustment
Measurement channels with full/half bridge mode are
cyclically calibrated during the runtime following the start
of the module. This mechanism improves long-term sta
bility (aging) and also the short-term stability of an ampli
fier if there are temperature fluctuations at the site of the
measuring device.
Background calibration briefly interrupts measurement
and - in place of the measured values from the trans
ducer - sends signals from an internal calibration source
to the AD converter (zero and reference signal).
