Hello everyone!
I'm working on a project involving the data acquirer "USB-2404-ui" and the load cell "Utilcell model 620". When I connect the DAQ device to the "Instacal" software, I can choose the ADC Timing mode, which allows me to set the data acquisition speed. I've noticed that when I select "High Speed," the values I obtain during testing are very unstable and not very precise.
To improve stability and precision, I have tried reducing the data acquisition speed by using options such as "High Resolution," "Best 50 Hz Rejection," and "Best 60 Hz Rejection." While this does lead to more stable and precise results, I encounter an issue when trying to open the data in Matlab. Matlab displays an error due to the low data acquisition frequency, and unfortunately, I am unable to modify this setting directly from Matlab.
Additionally, the load cell I'm using has six cables, where two of them are meant to stabilize the current in longer cables. I attempted connecting these additional cables in the same slot as the current input and output cables, as my DAQ device lacks extra slots for this type of cable. However, this solution did not improve result stability.
I would greatly appreciate any advice or suggestions on resolving this issue and achieving stable and precise results in Matlab, despite adjusting the data acquisition speed in "Instacal." Thank you all for your help!
