2.5 Calibration Window
The Calibration Window is used to display and
write to the CS5461 offset and gain calibration
registers. The user is also able to initiate the
CS5461’s calibration sequences that are used
to set the calibration values. Both AC and DC
calibrations can be run for offset and gain, for
either the voltage channel or the current chan-
nel, or both simultaneously. The user should
refer to the CS5461 data sheet for more details
on calibration.
