Hello, masters, I bought a device （NI cDAQ-9132and NI）to collect acceleration signals, but through the waveform, I found that the first 12 seconds of data is too large, seriously off the actual value. The data will be normal after 12 seconds, so I want to delete the data collected within 12 seconds of the device starting to collect. What should I do, please?
Solved! Go to Solution.
A photograph of your monitor is not really suitable to offer a solution. You can for example only start recording after a certain delay or you can trim the data later. Both are simple. How much LabVIEW programming do you know?
I have only been learning LabVIEW for 3 months. Could you please tell me how to delay recording, for example, start recording after 12 seconds? Thank you very much!

Set DAQmxRead to read data for exactly one second (number of samples = samplerate).
Then use a case structure to do "nothing" in the first 12 iterations of that while loop.
Do your analysis/"recording" only starting from 13th iteration on!
Btw. there is no "recording" in your VI, all I see is DAQ and some data analysis/display…
Thank you very much！The data will be packaged and transmitted to the train system home through certain protocols. The VI for transmission has been written but not uploaded
