HYST Select the thresholds for pressure hysteresis:
0
B
: Internal Configuration: 550kPa is the threshold from low to high pressure range
and 500kPa is the threshold from high to low pressure range.

B
: Customer Configuration - See (PressResult+3) and (PressResult+4)
ARANGE Automatic range selection for pressure measurement:
0
B
: Manual
1
B
: Automatic
If compensation is disabled (SensorConfig.6[RAW]==.1) a manual pressure range
measurement is performed, using the range specified by SensorConfig.9[PRANGE].
Automatic Pressure Range is not supported for raw (uncompensated)
measurements.
PRANGE Pressure range: (ignored if SensorConfig.10[ARANGE]==1)
0
B
: Low range (500kPa)
1
B
: High range (900kPa)
RAWTemp Selects source of raw temperature data for compensation
0
B
: Perform new raw temperature measurement
1
B
: Use raw temperature data supplied in *(PressResult+2)
