Trying to Setup a Load Cell

[Nabby]

I'm trying to setup a Load Cell in Labview an having some trouble. I'm a complete beginner in Labview.

So, I set it up with DAQ Assistant with a Bridge setup (Voltage with Excitation). I originally set it up as a Force setup but when I got incorrect outputs I decided to switch to Voltage and do the math myself. 

The equation I use to convert Voltage to Load is:

Load =  Vo/Vex * (Full Scale Capacity/Sensitivity)

When I put my load cell in my calibrated load frame I'm off by a factor of 10 (for ex. I read 4 kips instead of 40). 

The sensitivity of the LC is 2.2649 mV/V. 

I can't figure out what I'm doing wrong, any help would be appreciated. My block diagram and DAQ Assistant windows screenshots are attached.

What hardware are you using to read in the signal from the load cell?

Ah, sorry forgot to mention it - I addded to the original post.

If I understand the documentation correctly, you are off by a factor of 10 as the card reads in ratiometric and not absolute meaning the base units will be in V/V not in Volts. Youwould need to multiply by the excitation voltage to get the correct value.

Ahh, thanks! For me the manual was a little clear but that does make sense.

 could you share your code for this if you still have it?
