Measuring Accuracy: 1.0 grade

Feb 07, 2020 3 Replies

An Amazon meter is described as having "Measuring Accuracy: 1.0 grade". I found that there is a standard that defines the grades, but is there a simple answer to what "1.0 grade" means in percentage? (I know how difficult it can be to extract simple answers from standards.)


(very simplified version) The meter will be accurate to within 1% for a band of conditions set forth in the meter specs.Outside of those conditions the accuracy would not be as good as 1%.

Thank you. That is a perfect level of simple.
