problem with ni usb 6008

[paulmeaney]

Hi. I am currently using a NI USB 6008 device with 4 differential analog inputs. What i want to do is get the four inputs and average them and graph the result. The four inputs are thermistor outputs from a voltage divider circuit. I thought i had it working but it would only graph one point for me, and when i stopped the program a dilog box would appear with the message "Ressetting VI: USB-92xx Bulk Reader". Can anyone help with this please. It would be much appreciated. Thanks............

If it will not work, send me your vi, i will modified it.

Hi Paul,

Thanks for your post.

Please find attached an example VI that reads in differential measurements on 4 channels. The data is then plotted as raw data, and as an average.

The un-bundling and bundling of clusters in this VI eliminates an anomalous reading of 0 from an extra, non-existant, channel. I have noted this behaviour to R&D in the U.S.

I hope this helps. Let me know how you get on.

Thanks,
