一、测量方法依据JJG414-2011《光学经纬仪检定规程》,将5个平行光管的分划板调至无穷远,高低点平行光管分别安置在距水平位置平行光管各30°左右的位置。将经纬仪安置在检定台上并精确整平,依次从上至下对5个目标进行观测,并读记观测数据,每个目标读记两次,取平均值。用同样的方法自下而上进行观测,并读记观测结果,计算出竖直角,此为一测回,共测4个测回,计算出该仪器一测回竖直标准偏差。本文对DJ1
First, the measurement method based on JJG414-2011 “Optical Theodolite verification procedures”, the five parallel light pipe retouch adjusted to infinity, the level of parallel light pipe were placed in the horizontal position away from the horizontal position of about 30 ° of the light pipe . The theodolite placed on the test rig and accurate leveling, followed by five targets from top to bottom observations, and read the observed data, each target read twice, take the average. Using the same method bottom-up observations, and read the observation results, calculate the vertical angle, this is a test back, a total of 4 measured back to calculate the instrument measured back to a vertical standard deviation.
