Output Value = Filter [(A - B) + Offset]
Display units follows Source A plus relative
Source B
If E = OFF, Filter [A + Offset]
If E = ON, Output Value = Filter [B + Offset]
Display units follows active source.
Output Value =Output Value = Filter [Calculated Humidity + Offset] where
Source A is the Dry Bulb and Source B is the Wet Bulb
Note: Wet/Dry bulb temperatures are in degrees F and pressures are in
PSI. Output Value is % relative humidity. Useful temperature range is
10 to 350F
