摘要
电阻分压箱法作为JJF 1638-2017《多功能标准源校准规范》中直流电压的校准方法,常用于校准高精度低电压信号。本文介绍了电阻分压箱法校准多功能标准源直流电压的测量不确定度评定方法与评定实例,为评定多功能标准源直流电压的测量不确定度提供参考。
The resistance voltage divider method is used as a method for calibrating DC voltage in JJF 1638-2017 Calibration Specification for Multifunction Standard Sources,which is often used to calibrate high-precision and low-voltage signals.This paper introduces the measurement uncertainty evaluation method and evaluation examples of the DC voltage of the multifunction standard sources calibrated by the resistance divider box method,which provides a reference for evaluating the measurement uncertainty of the DC voltage of the multifunction standard sources.
