Select the thresholds for pressure hysteresis:
0 : Internal Configuration:550kPa is the threshold from low to high pressure range

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.
