Description
BACKUP_RESTORE
This parameter allows to save and to restore data according to factory and user calibration
procedures. It has the following options:
1, "Factory Cal Restore",
2, "Last Cal Restore",
3, "Default Data Restore",
4, "Shut-Down Data Restore",
5, "Sensor Data Restore",
11, "Factory Cal Backup",
12, "Last Cal Backup",
14, "Shut-Down Data Backup",
15, "Sensor Data Backup",
0, "None".
CAL_MIN_SPAN
This parameter contains the minimum calibration span value allowed. This minimum span
information is necessary to ensure that when calibration is done, the two calibrated points (high
and low) are not too close together. Unit derives from SENSOR_UNIT.
CAL_POINT_HI
This parameter contains the highest calibrated value. For calibration of the high limit point you give
the high measurement value (pressure) to the sensor and transfer this point as HIGH to the
transmitter. Unit derives from SENSOR_UNIT.
CAL_POINT_LO
This parameter contains the lowest calibrated value. For calibration of the low limit point you give
the low measurement value (pressure) to the sensor and transfer this point as LOW to the
transmitter. Unit derives from SENSOR_UNIT.
CAL_TEMPERATURE
This parameter contains the calibrated temperature value. Unit derives from
TEMPERATURE_UNIT.
COEFF_POL
This parameter contains the polynomial coefficients.
