accuracy

电动扳手就是以电源或电池为动力的扳手，是一种拧紧螺栓的工具。

Electric wrench is a power supply or battery powered wrench, is a tool to tighten bolts.

主要应用于钢结构安装行业，专门安装钢结构高强螺栓，高强度螺栓是用来连接钢结构接点的，能大大提高工作效率。

It is mainly used in steel structure installation industry. It is specially used to install high-strength bolts for steel structure. High strength bolts are used to connect steel structure joints, which can greatly improve work efficiency.

电动扳手精度很重要，一把好的电动扳手需要达到一定的技术要求；如果你买的电动扳手在测力的时候精度达不到，那么一定不是好电动扳手。

The accuracy of electric wrench is very important. A good electric wrench needs to meet certain technical requirements. If the accuracy of the electric wrench you buy can't reach when measuring the force, it must not be a good electric wrench.

灵敏度

sensitivity

一款灵敏度高的扳手不仅仅开机速度快，开机时间短，而且在我们使用时工作效率也快，这样大大地节省了测力的时间，尤其是企业进行测力，这个必须要考虑，因为是好的电动扳手的重要标准之一。

A wrench with high sensitivity not only has fast start-up speed and short start-up time, but also has fast work efficiency when we use it, which greatly saves the time of force measurement, especially for enterprises, which must be considered, because it is one of the important standards of good electric wrench.

稳定性

stability

电动扳手无论是精度再高还是灵敏度很高，只要是稳定性不好，那都是白搭，特别是电动扳手，这类电动扳手因为要搬运测力，而若固定不动的时候显示读数非常准确，一旦搬运移动测力了，这读数变化非常大，使得读数并不稳定，也就是说不动就有精度，一动精度就容易失灵，这样就不是好电动扳手。

No matter how high the accuracy or the sensitivity of the electric wrench is, as long as the stability is not good, it is useless, especially the electric wrench. This kind of electric wrench has to carry and measure the force, and if it is fixed, the reading is very accurate. Once it is moved and measured, the reading changes greatly, which makes the reading unstable, that is to say, it has accuracy and precision It's not easy for the electric wrench to malfunction.
