Hello.
I am pretty new Labview user, what I am trying to do is plot Force vs Stroke on simle XY graph.
I aquire the signal from Force Cell and LVDT. Read the value from Force Cell with no problems, although I have a problem with LVDT signal calibration as LVDT voltage range is (+2V to - 2V - I am reading +2V LVDT is fully extended which is = 0mm stroke [0,2V=1mm stroke]). Once I pushing LVDT rod into housing 0,2V is subtracts every 1mm stroke from +2V value.
Another problem I've encountred is fluctuating signal from LVDT +-0.05 which is quite significant regarding 0,2V=1mm.
Am I using XY graph properly as I don't have any plot on it while I run the program (after Index Array I've got two arrays one for each signal then I calibrate the signal for the right value and passing it to graph - if I understand code right??).
Also I have got a questing. Is there any possibility to set a zero point for LVDT on the begining of each test (for instance: LVDT is in a half way in and I'd like to set it as a zero point on the graph) as I not going to extend full LVDT rod each time when I run a program.
Many Thanks.
Greg
