精度
accuracy
電動扳手就是以電源或電池為動力的扳手，是一種擰緊螺栓的工具。
Electric wrench is a power supply or battery powered wrench, is a tool to tighten bolts.
主要應(yīng)用于鋼結(jié)構(gòu)安裝行業(yè)，專門安裝鋼結(jié)構(gòu)高強螺栓，高強度螺栓是用來連接鋼結(jié)構(gòu)接點的，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.
電動扳手精度很重要，一把好的電動扳手需要達到一定的技術(shù)要求；如果你買的電動扳手在測力的時候精度達不到，那么一定不是好電動扳手。
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.
靈敏度
sensitivity
一款靈敏度高的扳手不僅僅開機速度快，開機時間短，而且在我們使用時工作效率也快，這樣大大地節(jié)省了測力的時間，尤其是企業(yè)進行測力，這個必須要考慮，因為是好的電動扳手的重要標準之一。
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.
穩(wěn)定性
stability
電動扳手無論是精度再高還是靈敏度很高，只要是穩(wěn)定性不好，那都是白搭，特別是電動扳手，這類電動扳手因為要搬運測力，而若固定不動的時候顯示讀數(shù)非常準確，一旦搬運移動測力了，這讀數(shù)變化非常大，使得讀數(shù)并不穩(wěn)定，也就是說不動就有精度，一動精度就容易失靈，這樣就不是好電動扳手。
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.
