摘　　要：条码水准尺不仅是数字水准仪测量系统的重要组成部分,而且也是国家长度标准的载体。为确保国家长度单位量值的统一,必须对条码水准尺进行检定。文中从条码水准尺的编码原理出发,纠正现有检定规程中存在的错误;研究条码水准尺的检定方法、检定设备及检定项目;给出条码水准尺的正确检定参数。Barcode staff is not only an important component of digital level but also a carrier of national length standard. It is necessary to verify the barcode staff for ensuring length measurement traceability. Based on the unique feature of different barcode staff, it presents the calibration method in verification regulation, and describes calibration items, calibration methods and calibration device. And it also points out that it is very important to use the right test parameters.
