2.8.2 Rerange the transmitter
The range values command sets each of the lower and upper range analog values (4 and
20 mA/1–5 Vdc points) to a pressure. The lower range point represents 0 percent of range
and the upper range point represents 100 percent of range. In practice, the transmitter
range values may be changed as often as necessary to reflect changing process
requirements.
Select from one of the methods below to rerange the transmitter. Each method is unique;
examine all options closely before deciding which method works best for your process.
• Rerange by manually setting range points with a Field Communicator, AMS Device
Manager, or LOI.
• Rerange with a pressure input source and a Field Communicator, AMS Device Manager,
LOI, or local zero and span buttons.
