Saving Data

[sdonah2]

I am using the write labview measurement file express VI to save Data, but for some reason it will only save 100 data points. With a sampling rate of 1000Hz I only get 1/10 sec of data. I need to run the experiment for an extended period of time (1 hour). I have the acquisition on "acquire continuously" so I keep seeing new data on my graph/data table, but when I hit record it only records 100 data points then stops. If I change the mechanical action of the switch from "latch when pressed" to "switch when pressed" it will still only write 100 data points to a file, then It will make a new file with 100 more data points. I need all of the data in one file.

What functions are you using to acquire? Is it the DAQ Assistant or the DAQmx Read? For the assistant, the default setting is 100 samples to read. It's right above the sampling rate you set and called "Samples to Read".
