我们认为一把精度高的扭剪扳手应该有以下特点：

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

　　1. 拧紧扭矩准确——达不到预设扭矩那是不合格的。

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

　　2. 拧紧扭矩重复性高——每次是不是偏差很大，偏差很大可靠性就差，平均数和标准差需要一同去看。

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. 使用一段时间后扭矩的保持程度——扭剪扳手不是一次性产品，长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.

　　贵的和便宜的精度有没有区别？

Is there a difference in accuracy between expensive and cheap?

　　贵的准确性和重复性都相对更加可靠，不好的产品甚有超差的问题

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

　　贵的扭剪扳手在各个量程上的优势都是明显的

The advantages of expensive torque wrenches in various ranges are obvious

　　随着使用的增多，品质较差产品的准确性和重复性更加容易产品偏移

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