3 SPECIFICATIONS
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. 3.1.)
(2) Do not input an analog input voltage of -15V or less, or +15V 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 in which
the following conditions are satisfied.
(a) Offset value, gain value setting range: -10 to 10V
(b) { (gain value) - (offset value) } > 3.030V
(4) When an analog value that exceeds the range for the digital output value is
entered, the digital output value will be fixed at the maximum or minimum value.
