Fig. 3.2 Current Output Characteristic
POINT
(1) Within the digital input and analog output scopes of each output range, the
maximum resolution and accuracy are within the performance specification
range. Outside those scopes, however, they may not fall within the performance
specification range. (Avoid using the dotted line part in Fig. 3.2.)
(2) Set the offset and gain values of the user range setting within the range
satisfying the following conditions.
(a) Setting range when user range setting 3 is selected: 0 to 20mA
(b) (Gain value) > (Offset value)
If you attempt to make setting outside the setting range of (a), the "RUN" LED
flickers at 0.5s intervals.
Set the values within the setting range.
If you attempt to make setting outside the setting range of (b), the "RUN" LED
flickers at 0.5s intervals.
Make setting again.
