Uncertainty Setup

Note: this topic discusses mapping an uncertainty budget you created to the correct test point, not creating a budget from scratch.

Setting up uncertainty calculations is also different from the standard setup for most equipment. When choosing the test point to map your uncertainty budget to, you need to look at the number of channels and test points:

Here, we have 13 test points.

And we have 5 channels.

The result of this is that, worst case, you would have 13*5*4=260 test points in the resulting test points in your calibration event. In general, you'll be looking at [# test points]*[channels]*4 resulting test points. No matter what result you get, add one to that result.

In our example above, that gives us 261, which is the test point that will be used for all uncertainty calculations, as below:
