Abstract
D.C. potentiometer is widely used in precision measurement, verification, traceability and other fields due to its high accuracy and good stability. D.C. comparator potentiometer is by changing the automatic balance in the dc current comparator measuring the number of turns of the winding on the adjustment of measuring the resistance and determine a constant dc current, so as to obtain the continuous variable offset voltage constant resistance varying streaming potentiometer. According to JJF1059.1-2012Evaluation and expression of uncertainty in measurement, this paper analyzes the uncertainty of the measurement results which will useful to measurement uncertainty assessment of D.C. comparator potentiometers in future testing work.
