Help with the conversion math

[Ramius]

Sorry guys. The PDF was too large (22 pages as it had all the devices in the series) so to upload so I had to make it smaller! Yes it is a 0.5 - 4.5v type ratiometric device. My A/D is showing a reading of 7040 at zero psi and when I do a divide by 16 I get 440 which I am assuming means .440 volts? With a voltmeter I see .541 volts so now I have not been able to make any sense of all of this. My best guess is that this would indicate a voltage range of .440 to 4.440? Where .440 is zero and 4.440 would be at .07psi? If the A/D were 10 bit and giving 1023 as a maximum value then a reading of 7040 could not be possible. I am just so totally lost and confused with so many numbers! I just completely do not understand! Thanks!
