The input range should be set to whatever values you are expecting in units of pressure (something like 0-1000 for PT1, 0-5000 for PT2 and PT3, 0-50 for PT4), and not voltage.
If you look at your input range for the thermocouples, you see you have an input range of -328 to 100 degrees F (These are automatically scaled). The same concept applies for your pressure transducers and associated scales (you have a custom scale for these).
