I have setup a calibrated LVDT using the DAQ assist. Simple enough feature in my code: signal comes straight from the DAQ assistant, is subject to calibration math functions, and then out put to a numeric indicator. I want to be able to zero the LVDT when a button on the front panel is pressed. So say the lvdtis reading at a displacement already, I want that value to be zero and and any further displacement will be relative to that point. what a simple way of accomplishing this, unfortunately Im still learning trial by error with labview.

QUOTE (crelf @ Aug 6 2008, 12:10 AM) haha thanks i will remember that for the nxt time. I cant get the tree control unless norm sends me the 7.1 version. PM sent and hopefully that happens If it doesnt work out, any other suggestions?

hey all I didn't write this code but I am now in charge of modifying. (you all know how that goes). I don't have too much experience with labview, but enough to understand. What i need to do is replace the current method of entering 'loads' and 'rev triggers' in a way that is easier to use. I'd like to replace the 2 circled controls with 2 Tables, and have the user enter in loads into top row (or column) and revolutions at which the load occurs into the bottem row. There will need to be 2 tables(?) since there are two independent sides to this test rig. I gave it go with no luck so i was just wondering if there was any help to be offered. (using labview 7.1) Thank you

Hope all had a good holiday and long weekend. ive put up the area of code where it displays the loads put on each of the different (8) test specimens. can the change in load be carried out directly from (after) the doubles; replace the area where you all generated data? i know there is a space issue, but that can be taken care of.

QUOTE (mross @ Jul 3 2008, 09:03 AM) I appreciate the help mike. This isn't class work, it is code for an double slid ACTR (track roller) test machine. I did not write the (rather large amount of) code for it since its been in use long before i entered the company but i have been asked to modify it. I apologize that i can not post the code for our test rig. However, thank you for the direction. Anything else would be greatly appreciated

I have a chart that displays my load and indicators stating the current load values from test lab equipment. I've been asked to have my program also display ramp loading, so basically i have to chart the rate of change of the load. Can I some how graph the rate of change, or difference between a value and it's previous value?
