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.)

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.
