Thank you Henrik!
You and the people here are incredibly smart! I cannot thank all of you enough for your support and patience in teaching me so much and guiding me out of the "fog" I tend to get into. The high pressure side of the sensor is being fed with a .094" tube so there is not a lot of pressure to sense which is why the sensor has such a small range. The low side of the sensor is "static" pressure so you can compensate for the depth and still be able to know the speed when sub is travelling through water. In Microcode Studios ICD is where I can see the readings from the sensor. So since I know from the ICD that at zero pressure I get 110 and not 102.4 should I only adjust the low value or should I also adjust the high value assuming that the sensor has basically a 4 volt span (.5v to 4.5v) or does the high value stay the same? That is, a range from .5368 volts to 4.5368 volts. Again my most sincere thanks.
