I have a DAQ Assistant configured to read 2 channels at the same time. The data on DAQ assistant is accurate but wrong on chart

I have a DAQ Assistant configured to read 2 channels at the same time from new PXIe system (as i do on another PXIe system). 1 LVDT and 1 bridge transducer. While reading the data in DAQ assistant, the data it's OK, but displaying the data on chart or display, gives wrong data. 

What can i do?

Hi Elhanan,

I think you should do a full channel configuration in this case.

Also I suggest you to use DAQmx's VI separately and try to measure them without any dependency from each other. Except of DAQmx assistant use DAQmx read/write, Create Virtual channel , Timing VIs and etc. This link can help you to use DAQmx functions in LabVIEW.

I notice that in LabVIEW and MAX the sample rates are different, in MAX you tested the signal in 1K(Hz), but in LabVIEW you can see that the sample rate is set 100(Hz), try to correct as well.
