POINT
(1) Set within the analog input range and digital output range for each input range.
If these ranges are exceeded, the maximum resolution and accuracy may not
fall within the performance specifications. (Avoid use in the dotted area of Fig.
3.3.)
(2) Set the offset/gain values for the user setting range
the following conditions are satisfied.
(a) Gain value
(b) { (gain value) - (offset value) } > 9.70mA
(3) When an analog value that exceeds the range of the digital output value
entered, the digital output value will be fixed at the maximum or minimum
value.
