HART Communicator
To configure the scaled variable with a HART Communicator, perform the
following procedure:
1. From the HOME screen follow the fast key sequence shown.
2. Select OK after the control loop is set to manual.
3. Enter the scaled variable units.
a. Units can be up to six characters long and include A — Z, 0 — 9, -,
/,%, and *.
b. The first character is always an asterisk (*), which identifies the units
displayed are scaled variable units.
4. Select scaled data options
a. Select linear if the relationship between PV and scaled variable units
are linear. Linear prompts for two data points.
5. Enter pressure value position 1. Pressure values must be within the
range of the transmitter.
a. Enter the lower known value point considering any linear offset.
6. Enter scaled variable position 1.
a. Enter the lower known value point; this value must be no longer than
seven digits.
7. Enter pressure value position 2. Pressure values must be within the
range of the transmitter.
a. Enter the upper known value point.
8. Enter scaled variable position 2.
a. Enter custom unit equivalent to the upper known value point; this
value must be no longer than seven digits.
9. Enter linear offset.
10. Select OK to acknowledge that the loop can be returned to automatic
control.
