Less than expected number of samples in Labview

[ecclektik]

I have a USB 6009 device that will be measuring a signal coming from a load cell. I used the DAQ Assistant to start my program in Labview. I selected the continuous button for how many samples to read. I then wired the output signal to a "scale waveform" vi which is then wired to both an output graph on the front panel and a "write labview measurment file" vi. In the DAQ Assistant I left the sample rate and number of samples at the default of 1000 each. I run the program for a couple seconds and when I open the measurement file I only have 1000 data points. I have read through the help and it seems to indicate that if continuous is selected then it will record all samples until the program is stopped.

I have a while loop around the assistant vi and the stop terminal of the assistant vi is wired to the stop button of the while loop.

How do I get it to output all of the samples for as long as the program is run?

Consider setting the APPEND TO FILE option in the WRITE LABVIEW MEASUREMENT FILE vi.

Without it, the VI will write a new file every loop, overwriting the previous one.

Thank you forthe input. I was able to figure out the problem. It was a combination of moving the write to file into the while loop with the assistant and appending to file.
