I have NI 6008 USB on Win XP, I'm using the run-time of Labview 2010, I'm used to measure the force in kN, when I'm in the middle of the test the kN reading reads NaN, I believe that the connection/communication between NI USB and the PC exist because the force reading come back without resetting the device.
2nd question is that when using the 50kN loadcell the reading in the PC does not go beyond 20kN.
