POINT
(1) Set within the analog input range and digital output range for each input
range.
If these ranges are exceeded, the resolution and accuracy may not fall within
the performance specifications. (Avoid the use of dotted areas of Fig. 3.3.)
(2) Do not input an analog input current of 0mA or less, or 30mA or more. Doing
so can cause the breakdown of the elements.
(3) Set the offset/gain values for the user setting range within a range satisfying
the following conditions.
(a) Gain value
24mA, offset value 2mA
(b) { (gain value) - (offset value) } > 9.70mA
(4) When an analog value that exceeds the range of the digital output value is
entered, the digital output value will be fixed at the maximum or minimum
value.
