After test: URto be applied for 30 minutes, 24 to 48 hours beforemeasurement.
试验后：施加标称电压30分钟，于24至48小时之间测试。

In the laser tracking 3d coordinate measuring system, the self-calibration should be made beforemeasurement that would take effect mostly on the result.
在激光跟踪干涉三维坐标测量系统中，系统的标定精度直接影响着系统最终测量精度。

Before the measurement, copy the CPU Time values, and then paste them on to a spreadsheet.
