Good afternoon,
I have a Labview program to which a load cell is connected. I'm using a Hi-Speed USB Carrier chassis (NI USB-9162) and a NI 9219 board. The aim is to collect force for a few seconds for different swimming styles, and we want to achieve an acquisition rate of 100 Hz. The force data obtained is stored in an LVM file. However, we are facing some problems, such as:
1. The acquisition rate is not constant; sometimes I get 100Hz and sometimes I only get 70/80 Hz;
2. There is a very long delay between acquiring and displaying the data on the front panel;
3. There is also a very long delay when saving data
4. Labview stops after approximately 3450 samples and gives an error -200279.
I can't understand what the problem is. I've attached the program, the DAQ settings, and the error it gives us.
I hope you can help me 🙂
Regards
