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 1 within a range in which
the following conditions are satisfied.
(a) Gain value 24mA, offset value 2mA
(b) { (gain value) - (offset value) } > 9.70mA
(3) When an analog value that exceeds the range of the digital output value 2 is
entered, the digital output value will be fixed at the maximum or minimum
value.
