Command (Percent)
Command (Percent) displays the final command in %.
1.2
Position (Percent)
Position (Percent) displays the valve position in %.
1.3
Temperature (User Units)
Temperature (User Units) displays the temperature inside the
positioner.
1.4
Reference Pressure
PR (User Units)
PR (User Units) displays the pressure in port R. This port R is the
atmospheric reference pressure. It is subtracted from the others.
1.9
Valve Cycles (Cycles)
Valve Cycles (Cycles) are counted each time the positioner changes
direction. The movement must be beyond a dead-band window. This
window is set to 0.5% as a default, but can be changed using the
DTM.
1.13
Valve Travel (Percent)
Valve Travel (Percent) is counted in small increments every time the
valve moves beyond the dead-band window. The display of travel is
in % of full stroke.
1.14
Analog Output (AO)
The Analog Output provides a 4-20 mA feedback mechanism,
indicating the position of the valve, to the host system.
1.15
Analog Input (AI)
The Analog Input provides a 4-20 mA input mechanism to interface
with process variable transmitters.
1.16
Discrete Input (DI)
The Discrete Input provides a way for the user to either trigger a PST
or command the valve to a predetermined set point.

Step Test
The purpose of the step test is to allow the user to easily evaluate the
performance of the positioner from the local interface

Calibration
The Calibration menu allows the user to calibrate the positioner’s
sensors. The positioner can accurately control with only a Quick-Cal.
Typically this is all that is needed. Calibrate the friction calibration of
the positioner when upgrading to Pro diagnostics.
