8. From the adjustment menu, select the direction and
size of change required to set the travel to 0%.
Selecting large, medium, and small adjustments
causes changes of approximately 10.0°, 1.0°, and
0.1°, respectively, to the feedback arm rotation for a
sliding-stem valve or to the travel for a rotary valve.
If another adjustment is required, repeat step 8.
Otherwise, select Done and go to step 9.
9. From the adjustment menu, select the direction and
size of change required to set the travel to 100%.
Selecting large, medium, and small adjustments
causes changes of approximately 10.0°, 1.0°, and
0.1°, respectively, to the feedback arm rotation for a
sliding-stem valve or to the travel for a rotary valve.
If another adjustment is required, repeat step 9.
Otherwise, select Done and go to step 10.
10. From the adjustment menu, select the direction
and size of change required to set the travel to near
5%. Selecting large, medium, and small adjustments
causes changes of approximately 10.0°, 1.0°, and
0.1°, respectively, to the feedback arm rotation for a
sliding-stem valve or to the travel for a rotary valve.
If another adjustment is required, repeat step 10.
Otherwise, select Done and go to step 11.
11. From the adjustment menu, select the direction
and size of change required to set the travel to near
95%. Selecting large, medium, and small adjustments
causes changes of approximately 10.0°, 1.0°, and
0.1°, respectively, to the feedback arm rotation for a
sliding-stem valve or to the travel for a rotary valve.
If another adjustment is required, repeat step 11.
Otherwise, select Done and go to step 12.
12. Place the instrument In Service and verify that the
travel properly tracks the current source.
13. After manual calibration is completed manually set
the SIS parameters as described in Section 4. See
page 4-11 for End Point Pressure Control; page 4-14
Travel Deviation Alert Point and Travel Deviation
Time; and page 4-21 for Partial Stroke Pressure Limit.
Sensor Calibration
Pressure Sensors (1-3-2-1)
There are three pressure sensors: output A, output B
and supply. Select the appropriate menu depending
upon which pressure sensor you are calibrating.
Note
The pressure sensors are calibrated at
the factory and should not require
calibration.
Output Pressure Sensor Calibration
To calibrate the output pressure sensors, connect an
external reference gauge to the output being
calibrated. The gauge should be capable of measuring
maximum instrument supply pressure. From the
Calibrate menu, select Sensor Calibration and
Pressure Sensors. Depending upon the sensor you
wish to calibrate, select either Output A Sensor or
Output B Sensor. Follow the prompts on the Field
Communicator display to calibrate the instrument’s
output pressure sensor.
1. Adjust the supply pressure regulator to the desired
supply pressure. Press OK.
2. Select a) Zero only, or b) Zero and Span (gauge
required) sensor calibration.
a. If Zero only calibration is selected, wait until
output x pressure has completely exhausted, then
continue. Once calibration is completed, go to step
6. The output x pressure corresponds to A or B,
depending on which output you are calibrating.
b. If Zero and Span calibration is selected, wait
until output x pressure has completely exhausted,
then continue. You will then be asked to wait until
output x pressure has reached full supply, then
continue. The output x pressure corresponds to A
or B, depending on which output you are
calibrating. Proceed with step 3.
3. The instrument sets the output pressure to full
supply. The following message appears:
Use the Increase and
Decrease selections
until the displayed
pressure matches the
output x pressure.
The output x pressure corresponds to A or B,
depending on which output you are calibrating. Press
OK when you have read the message.
4. The value of the output pressure appears on the
display.
5. From the adjustment menu, select the direction and
size of adjustment to the displayed value. Selecting
