NI 9327 excitation voltage

[am_h]

Hi all,

I am setting up load cells with NI 9327 with MATLAB. I used 4 load sensors which using all slots/channels.  

ch4.ExcitationVoltage = 2.5; 

Does max voltage for full bridge is 10V for NI 9327 ? 

I got this error when the accumulative voltage >10V.

The error states that the channels in a task must have the same excitation voltage.

Please try creating separate tasks for each channel that has a different excitation voltage.

Yes, it has to be same voltage per channel, the question is does all accumulative voltage need to <10V ?

No, it is not sum of all excitation voltages. The excitation voltage is specified per channel and not total across all channels.
