Reading limit when reading an analog voltage from a Transducer Techniques DPM-3

I'm trying to use LabVIEW to read an analog voltage from a DPM-3.  It has a 10 Vdc range with 5 Vdc being it zero with 5-10 Vdc being the tension reading and 0-5 being the compression reading.  My problem is when trying to read the tension side, it only goes up to 5.23 Vdc on my numeric indicator.  I don't have any problems reading the compression side.  I am using a NI USB-6009 to read my voltages.  Is there a limit somewhere in the 6009 somewhere or did I not set something up correctly in my data acquisition?  Thanks.

You've probably done something wrong with the setup. What are you using to control the device? Is it the DAQ Assistant or the individual DAQmx functions? What did you set the input limits to? I don't know what the DAQ Assistant defaults to but with the DAQmx Create Channel, it defaults to +/- 5V.

I am using DAQmx commands, but i was not aware they came with a default value.  Thanks for the info Dennis, that solved that issue!!
