The Span Factor is used to adjust the pressure readings on the meter. It is
multiplied by the factory calibrated pressure to yield the displayed
pressure value.
Example - If the user determines that differential pressure is reading 2.3%
too low, they enter a Span Factor of 1.023 and afterward all differential
pressure values will be multiplied by 1.023.
