Note
The display (reported) units of the transmitter’s process value (PV) can be changed to
metric or imperial measurement units using the parameter Primary Variable Units
(page 120). However, this does not automatically re-scale the PV. Use the parameter PV
Scale Factor (page 121) to manually re-scale the value.
