It depends on what physical quantity is being measured. As far as the software is concerned, one way is to simulate the value of, for example, a specific error. The software error will be the difference of the obtained result from the set value.

David Flack

You need soft gauges. That is to say validated data sets for which you know the correct solution in advance.

I think you should use standard samples to regularly verify instrument accuracy. Alternatively, high-precision instruments can be used in parallel or series to calibrate the instrument under test.
