I want to calibrate multi-axis-load cell.

[Kkaeco]

Hi , I'm using NI cDAQ 9174 and NI 9237. I connected the multi-axis load cell. I want to calibrate separately for each axis. The example I'm currently using is continuous Measurement and Logging (NI-DAQmx), and what I modified here is the Physical Channel part of the Configuration Hardware part in the picture below. I checked well that the multi-axis data comes out when I run it in the main, but it's a result of calibration. I wonder how I can enter the mV/V value corresponding to each axis. If anyone can help, I'd greatly appreciate it.

I've had fun writing a calibration routine for inexpensive (and inherently "inaccurate") tri-axial accelerometer chips (I think I've posted about this in the LabVIEW Forum).  Never heard of a Load Cell until recently (also in the Forums), and the techniques/technology are "similar, but different".

I just typed "Calibrate multi-axis Load Cell" into a Search Engine, and found a lot of useful information out there, written by people who seem to know what they are talking about.  I recommend you do the same, especially since you know about the NI DAQ equipment you will be using, and how it interfaces with your load cell.

When/if you have a specific LabVIEW question about your implementation of the calibration procedure, come back here with a zipped attachment of the Calibration Project you are developing (preferably saved in LabVIEW 2021 or so, as many "experts" might not have the most recent versions installed).
