The digital values in the table above do not include the total precision (see page 31).
Conversion program using the scaling instruction (F282_SCAL)
Appropriate data interpolated from non-linear data can be obtained by creating a data table
with digital values and temperature data and then executing the scaling instruction
(F282_SCAL).
