added to convert this current to a voltage. Refer to Table 2
for the voltage output case, along with Figure 1 or Figure 2.
Calibration is a two step process for each of the five output
ranges shown in Table 2. First adjust the negative full scale
(zero for unipolar ranges). This is an offset adjust which
translates the output characteristic, i.e., affects each code by
the same amount.

Next adjust positive FS. This is a gain error adjustment, which
rotates the output characteristic about the negative FS value.
For the bipolar ranges, this approach leaves an error at the
zero code, whose maximum value is the same as for integral
nonlinearity error. In general, only two values of output may
be calibrated exactly; all others must tolerate some error.
Choosing the extreme end points (plus and minus full scale)
minimizes this distributed error for all other codes.
