You can't change the range of your pressure transducer from within MAX. That is set by whoever manufactured the pressure transducer. If you want to change the input range of the compact Fieldpoint module that it is connected to, you can do that within MAX. What analog fieldpoint module are you using?
Browse to the specific module you want to change within MAX. Right click and pick Go to Device configuration. Pick the Channel configuration tab. There you will be able to set the input range for each channel.
