Vlady said:When manufacturer calibrates this they calibrate it to this pressure setting and the voltage readings at that pressure. Never mind this all I need to know how to program it so it will do:
“HPA Vdc(output)
800hPa -0.004Vdc
820hPa 0.2857Vdc
850hPa 0.7151Vdc
870hPa 1.0009Vdc
900hPa 1.4294Vdc
920hPa 1.7152Vdc
950hPa 2.1436Vdc
Example:
Lets say it is reading current voltage of 0.14285Vdc so what I want it do is give me a read out based on looking only at 800 to 820hPa instead of the hole range of 800 to 1150hPa. So when it gets the voltage reading of 0.4932 it will give me corresponding readout based on looking only from 820 to 850hPa and so on”
Does this makes much since??

Thanks for your response…
Yes the value -0.0004 is correct calibrated in the factory. This is the accuracy that I have to work with actually it can be only to 4 digits should be accurate. To lot of people it may seem strange but it is not for what I am doing. And I don’t think I want to use 8bit I agree with JimB and others on using 16bit. I think this would give me plenty of digits but will be more difficult to work with..
