11.1.2.2 Manual Calibration
The values of the offset (OFC) and full-scale (FSC) calibration registers can be written to directly if there
are different offset and gain values desired to be used. The OFC or FSC registers are written to the
ADS1281 when the value in these controls changes and the user deselects the text box. For ease of
entry, the gain or offset values are entered only in the OFC or FSC controls; the actual values placed in
each of the three corresponding registers on the ADS1281 are displayed on this tab, as
Figure 25
illustrates.
