Changing the output scale

The AI function blocks can be configured to scale their output. The output scale is established by
defining a process variable value at 0% of scale and at 100% of scale. The output of the AI block will
be translated to a value between these two limits.
If you choose to use output scaling, note that it has no effect on the process values found in the
transducer block. This results in the following behaviors:
• ProLink II and the display use the process values in the transducer block. Therefore, the output
of a scaled AI block may differ from the value reported by other communication tools.
• Slug flow and flow cutoffs are configured in the transducer block. Therefore, output scaling
has no effect on the behavior of the transmitter with regard to slug flow or flow cutoffs.
To change the output scale, refer to the flowcharts in Figure 4-6.
