一种高准确度直流毫伏校准装置及其不确定度
The use of excel in evaluation of uncertainty for the result of the measurement for the error of indication of digital multimeter
Make full use of existing laboratory second-class standard resistance and high accuracy digital multimeters, Deploy dc constant current source with high stability, and presents a high accuracy components and measuring principle of the dc millivolt calibration system, the uncertainty of measurement were evaluated, through the verification of the calibration results, proved its accuracy and measurement uncertainty in line with expectations.
