20.4 Process Variable Channels
Use this view to configure process variable
measurements.
For process variable channels the top scale, bottom
scale, and units are set in two locations.
• First, set the scaling in the Process Variable view
(Channels tab). This is the input scaling. For
example, 4 to 20 mA = 0 to 150 deg C.
• Second, set the display scaling and units on the Measurements tab. Make sure the units
match in both locations.
An error will be shown if there is a problem with the scaling or the units (see Figure 20-6).

Use the Channels tab and the Summary view to configure channels. Select the Channel Type and
then select the Transducer.
Change to the Customize Transducer view to verify the correct Scale Factor, Units, and Transducer
Power setting.
The OK limits will be set according to the transducer you selected. They can be modified if needed.
