4.0 USE OF CALIBRATION DATA

Calibration data is provided in the form of calibration coefficients, so the
user can adjust and improve the accuracy of the analog output voltage over
the uncalibrated state. Each channel's unique offset and gain calibration
coefficients are stored in Flash memory. The use of software calibration
allows the elimination of hardware calibration potentiometers traditionally
used in producing precision analog outputs. A comparison of the
uncalibrated and software calibrated performance is shown to illustrate the
importance of the software calibration.

Software calibration uses some fairly complex equations. Acromag provides
software products (sold separately) to make communication with the board
and calibration easy. It relieves you from having to turn the equations of
the following sections into debugged software calibration code.
