Representation of output ranges

The tables below set out the digitalized representation of the output ranges by bipolar and
unipolar range. The resolution is 16 bits.
Please see the device manuals for each analog output module for assignment of the values
to the specific output values in each measuring range.
Table 3- 5 Bipolar output ranges

-32512 -117.593
-32512 -117.593
* When values > 32511 are specified, the output value is limited to 117.589 % or 0 % (0.0 V / 0.0 mA), depending on the
module used.
** When values < -32512 are specified, the output value is limited to -117.593 % or 0 % (0.0 V / 0.0 mA), depending on the
module used.
