Can u attach example excel files with uncertainty budget (multimeter, calibrator, DC Voltage)? Thank You!
What model DMM, Calibrator, and at what voltage?
Generically, you'll need the following as an example:
DMM spec for the voltage:
?(% reading + % scale + floor)
Calibrator specs:
?(% or ppm of output + floor)
The measured value/calibrator output:
10.0000 Vdc

And the other stuff:
Resolution of DMM and Calibrator
Sampled value statistics--avg and std dev or sampling mean (if you're reporting a sample average as your measurement result, then use the sampling mean).

An Excel file will only help if you already know what parameters you need and what to do with them.
There may be more but this is just an example.
Now you'll want to combine these parameters in a meaningful way. I'll post more or someone can carry on in the mean time.
