How to calibrate a vernier gas pressure sensor using the custom voltage with excitation

[YelBkCin]

Hello there fellow LabViewers.....

I have run into a wall and can not figure this problem out.  My question is as follows:  I am measuring gas pressure of an ideal gas and I am using a Verneir gas pressure sensor with the NI elvis board.  I am running into my problem with the calibration.  I am using the custom voltage with excitation analog input.  However, I am not this is even correct, but there is no toehr options using the DAQ assistant, so I am assuming this is correct.  Yet, when I try to calibrate this, I am completely lost, and the uncalibrated number stays at 4.99 and some change.  Does anyone out there know how to correct this problem??

Without knowing more about your setup this is just a wild hairy guess, but that output value sounds suspicious. Could you either be up against an input channel limit, or perhaps the input is not tied to what you think it is?
