我国自制的M—1万能磁力仪现已推广全国各地。我们现使用M—1万能磁力仪测量地磁场的垂直分量时,规定读数2次,以消除转向差,用原来的方法读数感到一是不方便,二是效率低,所以想法在磁力仪的骨架上做了一些小小的改进,以减少操作步骤及提高工作效率。大家知道在M—1磁力仪测量地磁场垂直分量读数二次时,首先要使罗盘在水平面上对南北方向,然 Our homemade M-1 universal magnetometer is now available throughout the country. We now use the M-1 universal magnetometer to measure the vertical component of the geomagnetic field, the provisions of the reading 2 times to eliminate the steering difference, using the original method of reading a sense of inconvenience, the second is inefficient, so the idea in the magnetometer skeleton Made some small improvements to reduce the steps and improve work efficiency. We all know that in the M-1 magnetometer to measure the vertical component of the magnetic field reading second, we must first make the compass in the horizontal plane on the north-south, of course
