Calibration Commands
The ADS1246/7/8 provide commands for three types of calibration: system gain calibration, system offset calibration and self offset calibration. Where absolute accuracy is needed, it is recommended that calibration be performed after power on, a change in temperature, a change of PGA and in some cases a change in channel.
