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.

目前，水平泡精度在电子水平仪上的调整和校正主要是手动校正的。操作人员通过水平泡检测装置在标准检测台上检测水平泡视角和内壁对称误差，然后通过夹具调整和校正水平泡，直到水平泡复合精度要求。
At present, the adjustment and calibration of horizontal bubble accuracy on electronic level instruments are mainly manually calibrated. The operator uses a horizontal bubble detection device to detect the angle of view and inner wall symmetry error of the horizontal bubble on a standard detection table, and then adjusts and corrects the horizontal bubble through a fixture until the horizontal bubble meets the required composite accuracy.

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.
