CALIBRATION
Sensor Calibration,
Upper and Lower Trim
Methods
Sensor Transducer
In order to calibrate the transmitter, run the Upper and Lower Trim Methods. If
your system does not support methods, manually configure the Transducer
Block parameters listed below.
1. Set MODE_BLK.TARGET to OOS
2. Set CAL_UNIT to supported engineering units in the Transducer Block
3. Apply physical pressure that corresponds to the lower calibration point
and allow the pressure to stabilize. The pressure must be between the
range limits defined in PRIMRY_VALUE_RANGE.
4. Set values of CAL_POINT_LO to correspond to the pressure applied to
the sensor.
5. Apply pressure, upper cal point.
6. Set CAL_POINT_HI
NOTE
CAL_POINT_HI must be within PRIMARY_VALUE_RANGE and greater than
CAL_POINT_LO + CAL_MIN_SPAN
7. Set SENSOR_CAL_DATE to the current date.
8. Set SENSOR_CAL_WHO to the person responsible for the calibration.
9. Set SENSOR _CAL_LOC to the calibration location.
10. Set SENSOR_CAL_METHOD to User Trim
11. Set MODE_BLK.TARGET to AUTO
Sensor Calibration, Zero
Trim Method
Sensor Transducer Block
In order to zero the transmitter, run the Zero Trim Method. If your system does
not support methods, manually configure the Transducer Block parameters
listed below.
1. Set MODE_BLK.TARGET to OOS
2. Apply zero pressure to the sensor and allow the to reading stabilize
3. Set values CAL_POINT_LO to 0
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 SENSOR_CAL_METHOD to User Trim
8. Set MODE_BLK.TARGET to AUTO
