Reading DAQ values problem

[mgarvey]

HEy all!

Ok here's my problem, i have the voltage output from a thermistor coming into my DAQ and a graph displaying the resulting values on the screen. This all works grand. The problem is that the daq is sampling the data so fast that it makes it difficult to present the graph as a credible graph. By this is mean, the output voltage is a constant 2.5V but LV is taking so many samples that the graph is displaying all the values arriving at the output which would be along the lines of say 2.51v,2.52v,2,49v,2.5v etc ie all the "unneccassary" values. i just want to smooth the graph out so it takes like maybe a 1000 or 100 samplesand outputs the average of this to the graph as this would i presume reduce the messyness of the graph.

Any help would be much appreciated.

Hi,

You can either decrease the acquisition rate of your DAQ board (I don't know how you did it, but there must be an input like scan rate opr something) or use one of the functions (DC waveform measurement, average, ...) that LabVIEW has to average the data that's comming from your acquisition and then present that data in a chart.

Hope this helps,
Paulo
