Calibration Menu
The Calibrate menu is used to calibrate the analog inputs and outputs, process pressure and
temperature sensors, as well as the actuator position and pressure sensors. Before entering the
Calibrate menu, the display will indicate that the system will be taken off-line and will ask the
user to accept the condition.
WARNING:
Taking the StarPac unit off line may cause the valve to stroke unexpectedly. Notify
personnel working nearby that the valve may stroke.
While the Calibrate menu is open, the system is in Test mode and will not respond to control
signals. To put the unit back on line you must press the LAST OPTION key until the display
prompts you, and then press ACCEPT. While you are in the Calibrate menu, the letter "T" will
flash on the right side of the display, indicating that the unit is in Test mode. The unit may also
change the valve position during some of the calibration processes that could affect the process
if it is not properly isolated. The Calibrate menu is arranged as shown.
Calibration Menu Tree

Edit Gain - This option allows you to change the gains from the default value to customize the
response of the system.
