– 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_range.unit'
•
CAL_POINT_LO
– 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_range.unit'
•
CAL_MIN_SPAN
– Minimum calibration span value allowed. Necessary to ensure that when calibration is done,
the two calibrated points (high and low) are not too close together. Unit derives from 'Sen-
sor_range.unit'
•
SCALE_IN
– Min/max-adjustment: Upper and lower calibrated points of the sensor. Unit derives from 'Sen-
sor_range.unit'
•
trimmed_value
– Sensor value after the trim processing. Unit derives from 'Sensor_range.unit'
•
sensor_sn
– Sensor serial number
•
temperature
– Process temperature. Selected as input to AIFB by setting 'Channel' = 4. Unit derives from
'Temperature.unit'
•
temperature_unit
– Unit code of 'Temperature', 'Max/Min_peak_temperature_value'
– °C, °F, K, °R
•
max_peak_temperature_value
– Holds the maximum process temperature. Write access resets to current value. Unit derives
from 'Temperature.unit'
– Write access resets to current value
•
min_peak_temperature_value
– Holds the minimum process temperature. Write access resets to current value. Unit derives
from 'Temperature.unit'
– Write access resets to current value
