注意事项/Matters needing attention：
尽管电子罗盘能够补偿磁干扰，但是用户应该选择一个磁干扰小的环境来 安装和使用。尽可能的选择远离铁、镍、磁铁、发动机和其他磁性物质放置 。如果 周围有这些磁介质，请至少需要维持 0.5m 远的距离。为保证产品达到测量效果,安 装时须采用非磁性螺丝刀和非铁质螺丝。
Although the electronic compass can compensate for magnetic interference, users should choose an environment with low magnetic interference to install and use. Choose to place away from iron, nickel, magnets, engines and other magnetic materials as much as possible. If there are these magnetic media around, please maintain a distance of at least 0.5m. In order to ensure that the product achieves the measurement effect, non-magnetic screwdrivers and non-iron screws must be used when installing.
务必严格避免磁铁、电动机等强磁物质靠近罗盘 10cm 之内，这可能会造成罗 盘的测量精度不可逆下降。 尽管罗盘能够在稳定的磁环境下补偿磁偏差，但是它不能补偿变化的磁干扰。例如：带直流电的电线产生磁场，如果直流电改变，磁场大小也将改变。电池是另一个 变化的干扰源。每个安装位置磁场环境都是不同的，用户必须评估该操作环境下的安装可行性。
It is necessary to strictly avoid strong magnetic substances such as magnets and motors close to the compass within 10cm, which may cause the measurement accuracy of the compass to decline irreversibly. Although a compass can compensate for magnetic deviation in a stable magnetic environment, it cannot compensate for varying magnetic interference. For example, a wire with direct current generates a magnetic field, and if the direct current changes, the magnetic field size will also change. Batteries are another changing source of interference. The magnetic field environment is different for each installation location, and the user must evaluate the installation feasibility for that operating environment.
我们建议的安装方式：将电子罗盘安装在垂直竖起的铝（或者其他无磁性的材料） 制杆上（转动杆垂直于转动平台，尽量做到避免大的外界磁场干扰）。
Our proposed installation method: Install the electronic compass on a vertical upright aluminum (or other non-magnetic material) rod (the rotating rod is perpendicular to the rotating platform, as far as possible to avoid large external magnetic field interference).
