我們認為一把精度高的扭剪扳手應該有以下特點：

We believe that a high-precision torsion wrench should have the following characteristics:

　　1. 擰緊扭矩準確——達不到預設扭矩那是不合格的。

1. Accurate tightening torque - failure to achieve the preset torque is considered unacceptable.

　　2. 擰緊扭矩重復性高——每次是不是偏差很大，偏差很大可靠性就差，平均數和標準差需要一同去看。

2. High repeatability of tightening torque - whether the deviation is large each time, the reliability is poor if the deviation is large, and the average and standard deviation need to be checked together.

　　3. 使用一段時間后扭矩的保持程度——扭剪扳手不是一次性產品，長期的可靠才是真可靠。

3. The degree of torque retention after use for a period of time - Torsion wrenches are not disposable products, long-term reliability is truly reliable.

　　貴的和便宜的精度有沒有區(qū)別？

Is there a difference in accuracy between expensive and cheap?

　　貴的準確性和重復性都相對更加可靠，不好的產品甚有超差的問題

Expensive accuracy and repeatability are relatively more reliable, and poor products may even have issues with exceeding standards

　　貴的扭剪扳手在各個量程上的優(yōu)勢都是明顯的

The advantages of expensive torque wrenches in various ranges are obvious

　　隨著使用的增多，品質較差產品的準確性和重復性更加容易產品偏移

As usage increases, the accuracy and repeatability of low-quality products become more prone to product deviation
