电子汽车衡示值误差测量结果的不确定度评定

Evaluation of the uncertainty of the measurement result of indication error of electronic truck scale

按照JJG539—97《数字指示秤》检定规程规定的环境条件及校准技术要求，采用M1级～M11级砝码对一台电子汽车衡测量重复性、偏载误差、电源电压稳定度和计算示值分辨力、低准确度等级砝码等几个方面引入的不确定度对电子汽车衡示值误差测量结果的不确定度进行分析。

According to the JJG 539-97 digital indicating scale verification regulation environmental conditions and calibration technology request, using the M1 to M11 class weight measurement repeatability, on an electronic truck scale eccentric load error, power supply voltage stability and calculate indication resolution, low accurate degree weights introduced not to determine the degree of electronic truck scale measurement result of indication error uncertainty analysis.
