Variable Voltage Output from NI 6008 using Labview 8.6

[Samsauce91]

Hey Guys,

So my goal is to create a voltage output from my NI USB 6008 that can be adjusted from 1-5V in Labview. (This output is going to a Mass Flow Controller that varies its pressure based on a 1-5V input) I'm using Labview 8.6 and so far I've used the DAQ to create a sin analog output but I can't figure out how to get a straight DC voltage output. Is this possible? Also when measuring the output so I hook the wire to the + and - or the + and gnd? Please help me!!!

Since you cannot use a waveform output with the 6008, you do exactly the same thing you are doing now - 1Samp for the DAQmx Write.

If I remember correctly, the analog out is single ended so the analog in should be configured the same.

Okay So I've gotten it so I can adjust the output voltage from A0 in the DAQ assistant window but how do I create a control of this output voltage in my Labview setup? I'm a total novice at labview btw.

The desire voltage is just a numeric control.

You should probably stop everything and take one of the free tutorials. A numeric control is a very basic concept.

Oh okay cool. Thanks for the help.
