PRESSURE COUNTS -
PRESSURE COUNTS is the reading from the analog-to-digital converter with no scaling or
offset. PRESSURE COUNTS is a 12-bit number read every 2 milliseconds.
PRESSURE ACTUAL -
PRESSURE ACTUAL is the value obtained by scaling and offsetting the pressure counts as
follows:
PRESSURE ACTUAL = PRESSURE SCALE x (PRESSURE PRESSURE
OFFSET)
