(1) Use the module within the digital input range and analog output range for
each output range setting.
If these ranges are exceeded, the maximum resolution and accuracy may not
fall within the performance specifications. (Avoid using the dotted line area
shown in Fig3.1.)
(2) In user range setting 3, the maximum and minimum output values are 6V and
-6V respectively. Obtain these values as follows using the gain and offset val-
ues.
Maximum analog output value = Gain value
Minimum analog output value = (Offset value - (Gain value - Offset value))
If a maximum or minimum value exceeds the output range, use user range
setting 2.
(3) Set the offset/gain values for the user range setting 2 within a range in which
the following conditions are satisfied.
(a) Setting range is from -12 to 12 V.
(b) { (Gain value) - (Offset value) } > A
<Value of A>
(4) Set the offset/gain values for the user range setting 3 within a range in which
the following conditions are satisfied.
(a) Setting range is from -0.5 to 6 V.
(b) { (Gain value) - (Offset value) } > A
<Value of A>
