根据质量比较仪在质量计量中的特点,对质量比较仪的计量性能的检测主要是考虑其重复性、各称量点之间测量的质量差值即偏载及局部示值误差的大小。由于质量比较仪与电子天平称量原理的不同,它是通过比较得出质量差值,而这个质量差值只在一定的范围以内,故线性示值误差仅针对一个小的、相对合理的电子显示范围进行测量。测量依据是JJF1326- According to the characteristics of the mass comparator in the quality measurement, the measurement of the mass comparator mainly considers its repeatability. The mass difference between the weighing points is the partial load and the magnitude of the local indication error. Due to the difference between the mass comparator and electronic balance weighing principle, it is through the comparison of the quality difference, and the quality difference is only within a certain range, so the linear indication error is only for a small, relatively reasonable electronic Display range for measurement. The measurement is based on JJF1326-
