There are DMMs from 2000 counts to 8 1/2 digits (millions of counts).In what situations, experiments, projects, etc it is Really Necessary a very high Resolution/Accuracy, like 5,6,7,8 1/2 digits?Thank you.

For example, I used to work for a company that made a very expensive attenuation tester. The accuracy was 0.1dB, but the resolution and stability was 0.001dB. Guess which the customer didn't care about

Guess which the customer didn't care about I think this is a very good point - depending on the price range of the equipment, the accuracy can be a lot less than the number of digits. No point in having 5 decimals in a +/- 1% device
