Best values for an RC low-pass filter
The load impedance specified in the product data sheet must not be less than 1 kohm when using the 0 to 10V output. The input impedance of your DAQ is (say) 1 Mohm so go for something that is about logarithmically halfway at \$\sqrt{1k\cdot1M}\$ = ~33k ohm.

However, you might want to check what leakage currents are produced by the DAQ's inputs to see that 33k does not create an offset error that is too large. I don't expect it will. You might want to consider how much error 33k series resistance produces when there is a 1M ohm to ground after it (about 3.3%). If this is too much choosing 10k will give an error of about 1%.
