一、测量方法1.测量依据JJF1110-2003《建筑工程质量检测器组校准规范》。2.环境条件温度(20±10)℃,相对湿度≤80%。3.测量标准专用校准台,其垂直度≤0.05mm/2m;校准台的测微头测量范围为(0~10)mm,分度值为0.01mm。4.被测对象建筑工程质量检测器组中的分度值为1mm/2m的垂直度检测尺(L=2m),其最大允许示值误差为±0.5mm/2m。5.测量方法将垂直度检测尺安装在专用校准台上,旋转校准台的测微头,将垂直度检测尺的指示表指针调整到零位,再将测微头数显读数装置置零。在量程范围内均
First, the measurement method 1 measurement based on JJF1110-2003 “construction quality detector calibration group.” 2. Environmental conditions Temperature (20 ± 10) ℃, relative humidity ≤ 80%. 3. Measurement standard special calibration table, the verticality ≤ 0.05mm / 2m; calibration station micrometer measurement range of (0 ~ 10) mm, sub-value of 0.01mm. 4. The object to be tested construction quality detector group division value of 1mm / 2m verticality ruler (L = 2m), the maximum allowable indication error of ± 0.5mm / 2m. 5. Measurement method The verticality detection scale mounted on a dedicated calibration stage, rotate the micrometer head of the calibration table, the verticality detection scale indicator pointer to zero, then the micrometer digital readout device zero. In the range of range
