检查和调整电子水平仪零位的方法 Method for checking and adjusting the zero position of an electronic level

将被检测到的电子水平仪放在已经调整到大致水平位置的平板(或机床导轨)上，靠近定位块。气泡稳定后，气泡末端的读数为a1，然后按水平方向调整180。°，准确放在原来的位置，根据次阅读的一侧，记下气泡另一端的阅读量为a2，两次阅读量差的一半为零位偏差=(a1-a2)/2格。如果零位偏差已经超过许可范围，则需要高速零位机构。另一种方法是找到相对零位点，而不是调整零位。如图，将电子水平仪放在平面上。气泡稳定后，读取右端数为a1，电子水平仪按水平方向调整180。°，准确地放在位置。气泡稳定后，右端读数为a2，两次读数差的一半为相对零位点；电子水平仪只有以相对零位点为标准，才能测量。如图所示，基准线向右穿过1.5格。

不得随意拧动非规定调节的螺丝、螺母。

第六，注意事项1、温度的变化会使测量产生偏差，在检测或使用过程中必须与热原和风源隔开。如果环境湿度与储存环境湿度不同，则在使用环境中使用前需要稳定3小时。

2、在进行测量之前，必须等待气泡完全静止。

3、使用水平仪后，工作面必须擦拭干净，涂上防锈剂，储存在清洁、干燥的地方。

4、本公司负责三包电子水平仪在规范使用和保管的前提下，因制造原因造成的缺陷和故障。

Place the detected electronic level on a flat plate (or machine guide rail) that has been adjusted to a roughly horizontal position, close to the positioning block. After the bubble stabilizes, the reading at the end of the bubble is a1, and then adjust 180 horizontally. Accurately place it in its original position, and based on the side of the second reading, record the reading volume of the other end of the bubble as a2. Half of the difference between the two readings is the zero position deviation=(a1-a2)/2 grid. If the zero position deviation has exceeded the allowable range, a high-speed zero position mechanism is required. Another method is to find the relative zero point, rather than adjusting the zero point. As shown in the picture, place the electronic level on a flat surface. After the bubble stabilizes, read the number a1 on the right end and adjust the electronic level by 180 in the horizontal direction. °, accurately placed in position. After the bubble stabilizes, the reading on the right end is a2, and half of the difference between the two readings is the relative zero point; An electronic level can only measure based on the relative zero point. As shown in the figure, the baseline crosses 1.5 grids to the right. Do not unscrew screws or nuts that are not adjusted according to regulations at will. Sixth, precautions: 1. Temperature changes can cause measurement deviations, and must be separated from the heat source and air source during testing or use. If the humidity of the environment is different from that of the storage environment, it needs to be stabilized for 3 hours before use in the environment. 2. Before taking measurements, it is necessary to wait for the bubbles to completely come to a complete stop. 3. After using the level, the working surface must be wiped clean, coated with rust inhibitor, and stored in a clean and dry place. 4. Our company is responsible for the defects and malfunctions caused by manufacturing reasons of the three package electronic level instrument, under the premise of standardized use and storage.
