weird voltage values from AI channel

[hmmille@my-deja.com]

I have a vi that reads voltage values from an analog input channel. The
readings should be in millivolts, but I'm getting errant readings of
between 1 and 10. I do get some actual voltage data, but these strange
values are also in the array. Does anyone have this same problem? I am
reading the voltage data from a PMT.

Check up your subVis about the units in output. Are they Volts or mVolts and
then check your calculations.If there is a lot of noise together with your
weird values check your grounds (and the ground of your PC) or the
connections.Try to turn on first your device and then run Labview-->VI.
Debug your array with ''Index Array''.
If you can send more information it would be helpful.
