Recall Factory Trim
To recall a factory trim on the transmitter, run the Recall Factory Trim. If your
system does not support methods, manually configure the Transducer Block
parameters listed below.
1. Set MODE_BLK.TARGET to OOS.
2. Set SENSOR_CAL_METHOD to Factory Trim.
3. Set SET_FACTORY_TRIM to Recall.
4. Set SENSOR_CAL_DATE to the current date.
5. Set SENSOR_CAL_WHO to the person responsible for the
calibration.
6. Set SENSOR _CAL_LOC to the calibration location.
7. Set MODE_BLK.TARGET to AUTO.
NOTE
When sensor type is changed, the transmitter reverts to the factory trim.
Changing sensor type causes you to loose any trim performed on the
transmitter.

Diagnostics
Table 3-5 lists the potential errors and the possible corrective actions for the
given values. The corrective actions are in order of increasing system level
compromises. The first step should always be to reset the transmitter and
then if the error persists, try the steps in Table 3-5. Start with the first
corrective action and then try the second.
