Calibration Impacts Data Quality

When a channel on an analog input module is being calibrated, the Notch Filter setting for that channel changes to 10 Hz. The I.Chxx.Uncertain tag is set to 1 for that channel until calibration is completed.

Grouped inputs share an Analog-to-Digital converter. As a result when any input channel is in the calibration process, the

I.Chxx.Uncertain

tag is set to 1 for other input channels in that group. This is because the data sampling rate slows for all input channels in the group.
