* Sensor can toggle between standard/high range mode range mode while in use. Standard/high range mode sensor is one conguraon and associated
sensor board hardware. Ultralow range mode sensor is a dierent conguraon and associated sensor board. While you can toggle between standard and
high range modes you cannot toggle between the standard/high and ultralow modes since these are two dierent sensor boards. Two slope calibraons are
stored in dual mode standard/high sensors; slope low is used for the standard mode and slope high for the high mode. Slope calibraons are automacally
assigned based upon range mode in use for sensor at me when calibraon is performed. The ultralow range mode only uses the single low slope (slope high
is unused).
