LabVIEW
Error while acquiring accelerometer data
I'm a student just getting acquainted with LabVIEW so this might be a simple fix, but it's over my head.
We have a simple heat exchanger/heater water loop and we're trying to get vibration data from the pump in the loop with a magnetic mounted tri-axial accelerometer. We're using a cDaq-9188 chassis with a 9234 high frequency card to get the data from a PCB model 356A15 accelerometer. We have a working LabVIEW program for the rest of the data (RTDs, flow meters, etc) so the chassis is functioning.
We originally tried to simply add to the working program to get the accelerometer data but no solution was found. So to try to understand the basics of getting the data, and to ensure the card/accelerometer is functioning, I made a new project to only retrieve the accelerometer data.
Unfortunately we are still getting the same error : -52005
I've tried every search combo to find this but the only thing I stumbled on was a bug fix from NI related to that error with no further explanation.
I'm assuming I'm missing something very basic, so either an explanation or link to this problem being solved previously would be appreciated. The .VI file is attached, but its not much to look at.
Also, we're using LabVIEW 2020 SP1.
Just guessing here, I don't use DAQ assistant.
Your sample rate is 1000Hz; you are set up to acquire 5 samples at a time, or in other words acquires samples every 5ms. This is normally too fast, set the number of sample to 100 or 200, so you update every 5 - 10 Hz. See if that works.

EDIT: Also just saw that you are using a 9134. Look in the manual, your sample rate is incorrect. 1.652 kSa/s is the minimum rate. See snippet below. Change the number of samples and your sample rate.
