摘　　要：水平仪检定器是用于校准钳工水平仪、框式水平仪分度值误差的主要计量标准器具,其准确度直接影响水平仪的量值溯源质量。通过分析水平仪检定器工作原理,指出了示值误差是表征水平仪检定器准确度性能的指标,提出了水平仪检定器示值误差数学模型,分析了水平仪检定器示值误差的测量关键。The calibrators for levels are used for calibrating the division value error of the shaft levels and frame levels.The accuracy of the level calibrator directly affects the traceability quality of the level.Based on the analysis of working principle of the level calibrators,it is pointed out that the indication error is an index to characterize the accuracy of the level calibrator,and a general mathematical model of the indication error is put forward.The key to measuring the indication error of the calibrators for levels is analyzed.
