| Abstract: | Through using the Fluke 8508A digital reference multimeter and the Guildline 9334A DC standard resistor as measurement standard, using the method of current-volt transfer, the accurate and reliable calibration to the accurate DC standard current source can be realized. The accurate evaluation of uncertainty proofs that the calibration of the accurate DC standard current source which the error to be ±0.003% can be successfully achieved. This increases the ability of calibration to the accurate DC studard current source greatly . |
