Uncertainty of NI 9235

[Varlistay]

Hello, everyone.

Does somebody know how to calculate Uncertainty of NI 9235 ?

Varlistay,

The spec sheet (here) contains the information you need.  However, don't forget to include the uncertaintly of the strain gauge, I've always found that the strain gauge is the biggest part of the total uncertainty.

Thank you dr2

But I doubt something in this spec.

I think the offset error of NI 9235 that already calibrated is too high (In spec said 0.15% of range).

Can I reduce of remove this source of error by zero adjust or another method?

Sorry for bad grammar
