Output Value = Filter [Convert Source A in Pressure to
Altitude + Offset]
Note: Pressure Altitude calculation is based on the
International Standard Atmosphere 1976. Source A is a
pressure signal and needs to be in PSI units for the
calculation. The calculation is accurate from sea level to
90,000 feet. The standard is based on an altitude of 0 feet
(sea level) pressure of 14.6967 PSI and a temperature of 59
degrees F. Result of calculation is in feet.

Output Value = Filter [Maximum Value (A : B : C : D) +

Display units follows Source with maximum value.
Output Value = Filter [Calculated RH compensated
for temperature + Offset].
Note: Source A is RH measured value from an
uncompensated Vaisala RH sensor. Source B is
temperature of the RH sensor in degrees F. The result
is a "corrected" RH measured value. This calculation
is effective over the temperature range of -75F to
350F.
