working.

2. Press + repeatedly until SETUP appears.
3. Press * to return to SETUP menuCALIB appears.

Correct for Over Travel
WARNING
During Calibration and Configuration the valve moves. Keep
hands clear. Isolate the valve from the process. Calibration
functions stroke the valve over its full range.
On some valves the full travel is larger than the nominal travel of the valve and it may be
desirable to have the reported 100% position correspond to the nominal travel rather than
the full stroke. The STOP OP option allows this correction. Use this procedure to make a
correction.
1. From CALIB press * to display Stops.
2. Press + to display STOP OP.
3. Press * to move valve to the 100% position.
4. Use the + and - buttons to position the valve to the nominal full open position.
5. Press * to accept this position as the new 100% position.
