8.1.4 Background calibration / autoadjustment
Measurement channels with full/half bridge mode are cyclically calibrated dur
ing the runtime following the start of the module. This mechanism improves
long-term stability (aging) and also the short-term stability of an amplifier 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 transducer - sends signals from an internal calibra
tion source to the AD converter (zero and reference signal).
Background calibration is available for the following amplifiers: MX840B,
MX440B, MX430B and MX238B.
