Abstract In view of the fact that the only measurement method can not meet the calibration requirements of high accuracy and full range differential resistor reading instrument, the digital multimeter is proposed as the measurement standard, and the comparison method is used to calibrate the resistance ratio indication error, resistance indication error. The uncertainty of measurement results of resistance ratio indication error is analyzed, and the expanded uncertainty is 6×10-5(k=2). In order to improve the accuracy of measurement results, the method of adding variable resistance into the calibration circuit is used to measure the influence of core wire resistance on indication value. At the same time, the four wire resistance linearity experiment is carried out to analyze the reliability of DMM as the measurement standard, and then verify the scientificity of calibration method.
