"Absolute error of my measurement" service allows evaluating measurement precision considering measurement uncertainty (or error) in absolute value. It is important in case you are making measurements at the range edge, when the value of error contributes into the value displayed by the device.
To get the range of values it’s enough to enter the evaluation of the value under measurement into Value box and to see the range of possible values including all of the standard errors.
