"1% +/- 2 counts" literally is something you might see on a spec sheet. The percentage is assumed to be +/-, just like with components (e.g., a "10% tolerance resistor" is assumed to be +/- 10%). Never assume a tolerance is unidirectional unless it explicitly states as much (that is something I have seen, but only rarely).
Excellent video. I have a question, is the calculation made on the measurement of 1.02 V accurate or precision? I understand that accuracy is qualitative and is associated with measurement error and that what is calculated is precision.
Technically, measurement precision deals with repeatability (i.e., measurement spread across several readings). In common usage, it refers to how far off the measurement is from an accepted or true value (i.e., accuracy). Further, it is sometimes used to denote resolution (i.e., finest or least significant digit). Confusing? Yes, because it depends on your audience! I find it best to just explain what it is that you're after. Similar situation to the word "theory". In common usage, it's often synonymous with "hypothesis" or even "guess", but it has an entirely different meaning to scientists!
Excellent explanation Professor. Thank you so much.. it was extremely useful..If we need to know more about 3 1/2 or 4 3/4 basics, how do we get in touch with you ? Also, I have doubts on Accuracy and Resolution ..
Excellent explanation. Thank you very much.
Thank you!
You wrote "1% ± 2 counts". IMHO you should have written ±(1% + 2 counts). Your examples clarified this thou.

Good explanation. 👍

You can ask questions here so that others can benefit as well. I am not available for email queries unless you are one of my students.
