With the development of technology, the mechanized age is getting closer and closer to us. In the outbreak of COVID-19, many high-tech products are coming into view. But machinery is the fundamental source of the whole industrial country. Then the machinery must be related to the instrument. Today, Xiaobian will introduce to you in detail an essential tool in machinery - torque wrench.

扭矩扳手，扭矩扳手又叫力矩扳手、扭力扳手、扭矩可调扳手，是扳手的一种，目前市场上常见的有手动扭力扳手，电动扭力扳手，气动扭力扳手。

Torque wrench, also known as torque wrench, torque wrench and torque adjustable wrench, is a kind of wrench. At present, manual torque wrench, electric torque wrench and pneumatic torque wrench are common in the market.

而数显扭力扳手顾名思义就是带数字显示的扭力扳手（扭矩扳手，力矩扳手），它有别于一般的扭力扳手，拥有强大的操作功能，包含扭力设定；单位设定；模式设定；数值储存；数值清除；数值输出以及网络校正功能，数字扭力扳手，铬钒钢材质。它是扭矩扳手中的一种，不但能够当施加的扭矩达到设定值时，扳手会发出“卡塔”声响或者扳手连接处折弯一点角度，而且会通过数字显示屏或者LED灯来提示使用者，而且在扭矩的设定上也能够通过按键和数字显示屏来完成，比之非数显扭力扳手更方便也更易与操作。总而言之数显扭力扳手是扭矩扳手中更易于操作的，它通过安装数字显示屏降低了对操作人员的要求。（PS：来自搜索引擎）

The digital display torque wrench, as its name implies, is a torque wrench with digital display (torque wrench, torque wrench). It is different from the general torque wrench and has powerful operation function, including torque setting; Unit setting; Mode setting; Value storage; Clear the value; Digital output and network correction function, digital torque wrench, made of chrome vanadium steel. It is one of the most advanced torque wrenches. When the applied torque reaches the set value, the wrench will make a "click" sound or bend a little angle at the wrench connection, and will prompt the user through the digital display screen or LED light. Moreover, the torque setting can also be completed through the keys and digital display screen, It is more convenient and easier to operate than non digital torque wrench. In a word, the digital display torque wrench is the most easy to operate torque wrench. It reduces the requirements for operators by installing a digital display screen. (PS: from search engine)

首先我们来看扭矩扳手的分类，扭矩扳手有指针式和预置式两种，指针式的扭矩扳手使用方法很简单，在达到一定力矩之后指针就会指向相应的数字，预置式扭矩扳手使用方法更简单，需要多大力矩就调整到多大力矩。

First of all, let's look at the classification of torque wrenches. There are two types of torque wrenches: pointer type and preset type. The use method of pointer type torque wrench is very simple. After reaching a certain torque, the pointer will point to the corresponding number. The use method of preset torque wrench is simpler, and it can be adjusted to the required torque.

1、旋下手把后端的电池盖，正极朝前装入 2 节 5 号电池，然后旋紧电池盖；

1. Unscrew the battery cover at the back end of the handle, install 2 No. 5 batteries with the positive pole facing forward, and then tighten the battery cover;

2、短按“O/C”键，开启电源，液晶显示器字符全显，扳手开始自检，3 秒后置零；

2. Short press the "O / C" key to turn on the power supply, the LCD characters are fully displayed, the wrench starts self inspection, and set to zero after 3 seconds;

3、单位选择，按“▼”选择所需的测量单位；

3. Unit selection: press "▼" to select the required measurement unit;

4、测量方式选择：按“M”键，选择“跟踪 F”或“峰值 H”模式；

4. Measurement mode selection: press "m" key to select "tracking F" or "peak H" mode;

5、扭矩值报警预置：按“M”至“预置 P”模式，再按“P”键确定所需预置扭矩值的位数，按 “▲”及“▼”键确定所需预置报警数值，预置结束后按“M”键退出预置模式，回到“跟踪 F”状态，或再按一次“M”键进入“峰值 H”状态。

5. Torque value alarm preset: press "m" to "preset P" mode, then press "P" key to determine the number of digits of the required preset torque value, press "▲" and "▼" keys to determine the required preset alarm value, press "m" key to exit the preset mode and return to "tracking F" state, or press "m" key again to enter "peak H" state.

6、清零：在测量前将扳手处在自然水平空载状态下，按“O/C”键清除现有的显示数值，使当 前状态为“零位” 。

6. Reset: before measurement, put the wrench in the natural level no-load state, press the "O / C" key to clear the existing displayed value, so that the current state is "zero".

7、测量：分为跟踪测值、峰值测值、预置测值

7. Measurement: it is divided into tracking measured value, peak measured value and preset measured value

8、关机：手动关机（当扳手在两分钟未进行任何操作会自动关机）

8. Shutdown: manual shutdown (when the wrench does not operate for two minutes, it will automatically shut down)

自动关机（长按O/C键即可）

Automatic shutdown (long press O / C key)

就是我们该如何读数了？

Is how we should read?

1、如果是带表扭力仪器.直接读取指针所指示的数据为测量数据值.

1. If it is a torque instrument with a meter The data indicated by the direct reading pointer is the measured data value

2、如果是套筒加副刻度指示器.应先读取主刻度上的刻度值,再加上副刻度或微分筒上的刻度值之和为测量数据值

2. If it is a sleeve plus a secondary scale indicator The scale value on the main scale shall be read first, and the sum of the scale value on the sub scale or differential cylinder shall be the measured data value

以上就是扭矩扳手的使用方法，那么当你了解了扭矩扳手，是不是该考虑一下如何去选择一个质量上乘的扭矩扳手。

The above is how to use the torque wrench. When you understand the torque wrench, should you consider how to choose a high-quality torque wrench.
