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。
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.

工作原泡水平仪的玻璃管内壁是一个具有一定曲率半径的曲面。当电子水平仪倾斜时，气泡会移动到电子水平仪上升的一端。水平气泡内壁曲率半径越大，分辨率越高，曲率半径越小，分辨率越低。因此，水平气泡的曲率半径决定了产品的精度。
The inner wall of the glass tube of the working bubble level is a curved surface with a certain radius of curvature. When the electronic level is tilted, the bubble will move to the rising end of the electronic level.

在称重过程中，由于放置位置不均匀，电子水平仪会出现测量误差。称重精度越大，偏差越大(如分析水平仪和少量电子水平仪)，所以大多数电子水平仪都带来了调节水平的功能。
During the weighing process, the electronic level may experience measurement errors due to uneven placement. The greater the weighing accuracy, the greater the deviation (such as analytical level and a small number of electronic level instruments), so most electronic level instruments come with the function of adjusting the level.

水平仪是测量小角度的常用量具。在机械工业和仪器制造中，它用于测量机床设备导轨的平整度和平行度、设备安装的水平位置和垂直位置等。根据水平仪的不同形状，可分为框架水平仪和条形水平仪。
A level is a commonly used measuring tool for measuring small angles. In the mechanical industry and instrument manufacturing, it is used to measure the flatness and parallelism of machine tool equipment rails, as well as the horizontal and vertical positions of equipment installation. According to the different shapes of the spirit level, it can be divided into frame spirit level and strip spirit level.
