Facing issue measuring weight using Load Cell and NI 9218 with DSUB and 9171 chassis

[HS11]

Hello all,

I am using NI 9218 with DSUB along with 9171 chassis to measure weight using a Load Cell. My VI includes DAQ Assistant. The excitation I am using is internal 3.3 V and in Force (Bridge) mode, (Tried Voltage as well as Bridge input mode too). On trying to perform the task I have observed that the signal I am getting is Sinusoidal in nature and on putting the load it appears as a ripples in that sinusoidal base. So, as it is sinusoidal I am getting varying mean value and hence the varying calculated weight.

I might be missing some thing and performing the task in correctly. Hence, seek guidance from your end. 

Thanks in advance.

Dear HS11,

Can you please attach your code? preferably the project you've written your code in.

Apart from attaching your code, it would be of help if you provide us with the following details:

- Steps followed when setting up the DAQ Assistant

- Screenshot of the data output graph

- Load cell that is being used
