labview- datalog/output file

[mekdeng]

Hello Group.

I am using DAQ assistant to do a strain measurement experiment using strain gages. How do export the values shown in the graph in test run? How do I build a VI to retreive these values into a spreadsheet?..

Thank you

Hi,

I don't think you can directly take the test run data to a file. However, you can make a VI that will help you do the same and once you start acquiring values you want, you simply have to save them in what ever format you want (excel/datalog/bin etc). You can see examples that are available for both the cases and merge the examples according to your usage to make a new one!!!

hope it helps.

Thank you Sreedhar,

but I tried to do that but did not quite worked out for me. I am not a regular user of LabVIEW, and this is my first time using so I am having some hardtime merging to VIs.

I was wondering whether anyone know of any specific VI i could use to do achieve my goal?

Thank you

Hi Hari,

Post your VI and tell in which format you want to save it

Hi Dev,

I am attaching a strain measurement VI with this message. I would like to use this VI and do a test run and as well get the results in excel. What do I need to add to this VI to get what I desired?

Thank you in advance

OOops ...I forgot to attach the VI in the last message... Here it is

where is the VI???

Hi Hari,

Modified your VI to read strain data in 2D array format and save it to spread sheet file.

Hope this helps

any doubts, do get back

Or use this VI to save waveform data to a spreadsheet text

Hi,

I have made a modification only in the save part, as I don't have and hardware and consider that your acquisition example is working fine...

do get back if you have problems.
