Hi,
Carried out first test for my data acquisition project for uni today. The general basic operation is I am carrying out a test on a super duplex steel tube. A new load is applied every 30 seconds and the program should record when the change in strain occurs which is then plotted on a table in an excell file. Some slight issues that I was hoping someone could maybe explain to me...
1) get a negative value. "-2.107" unsure how to solve this. Have swapped wires around and no luck. Not sure if maybe he filter in my lab view is causing problems as I get an error with it. Problems with differential amplifier maybe?
2) I wanted my program to plot ten results before save to a file. However it only takes one value and then saves. This means to get the next value when a new load is applied I have to save to a new document.
I will post the actual program soon. Any ideas help would be much appreciated.
Cheers
Mike.
