DAQmx Error -200447 When Using NI MAX Scale Table with Load Cell

[testengineer06]

I am attempting to acquire data from a load cell using a PXIe-4331 strain/bridge module. Prior to developing the VI, I configured and recorded both the prescaled (mV/V) and scaled (Newton) values in the table within NI MAX. I then created a data acquisition VI using a DAQmx sequence, as shown in the attached program.

However, I encounter DAQmx error -200447, which prevents the program from running. Alternatively, when I do not retrieve the prescaled/scaled table from NI MAX and instead manually enter the scale table via the control panel, the program operates correctly.

Despite this workaround, my objective is to use the scale table configured in NI MAX. Could you please advise on how to resolve this issue?

You could try changing the AI Force Bridge (Table) channel type? For the PXIe‑4331, you could configure an Analog Input → Bridge (V/V) channel and then applying your custom scale (mV/V → N). Using AI Force Bridge can conflict with a custom scale from NI‑MAX and trigger error ‑200447
