Torque wrench, also known as torque wrench, torque wrench, torque adjustable wrench, is a type of wrench that is commonly used in the market, including manual torque wrench, electric torque wrench, and pneumatic torque wrench.

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。它是扭矩扳手中高级的一种，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于操作。总而言之数显扭力扳手是扭矩扳手中易于操作的，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）

As the name suggests, a digital torque wrench is a torque wrench with digital display (torque wrench, torque wrench), which is different from ordinary torque wrenches and has powerful operating functions, including torque setting; Unit setting; Mode setting; Numerical storage; Value clearing; Numerical output and network correction function, digital torque wrench, made of chrome vanadium steel material. It is an advanced type of torque wrench, which not only makes a "snap" sound or bends the wrench connection slightly when the applied torque reaches the set value, but also prompts the user through a digital display screen or LED light. In addition, the torque setting can also be achieved through buttons and digital display screens, making it more convenient and easy to operate compared to non digital torque wrenches. In summary, digital torque wrench is an easy to operate torque wrench, which reduces the requirements for operators by installing a digital display screen. (PS: from search engines)

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。

Firstly, let's take a look at the classification of torque wrenches. There are two types of torque wrenches: pointer type and preset type. The use of pointer type torque wrenches is very simple, and once a certain torque is reached, the pointer will point to the corresponding number. The use of preset type torque wrenches is simpler, and they can be adjusted to the required torque.

接下来就是如何操作扭矩扳手了？Ps:数显扭矩扳手

Next is how to operate the torque wrench? Ps: Digital torque wrench

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；

Unscrew the battery cover at the back of the handle, insert two No. 5 batteries with the positive electrode facing forward, and then tighten the battery cover;

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；

Short press the "O/C" button to turn on the power, the LCD display will display all characters, the wrench will start self checking, and reset to zero after 3 seconds;

单位选择，按“▼”选择所需的测量单位；

Unit selection, press "▼" to select the desired measurement unit;

测量方式选择：按“M”键，选择“跟踪 F”或“峰值 H”模式；

Measurement method selection: Press the "M" key and select the "Tracking F" or "Peak H" mode;

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。

Torque value alarm preset: Press "M" to "preset P" mode, then press "P" key to determine the number of digits for the desired preset torque value, press "▲" and "▼" keys to determine the desired preset alarm value. After the preset is completed, press "M" key to exit the preset mode and return to the "tracking F" state, or press "M" key again to enter the "peak H" state.

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” 。

Zeroing: Before measuring, place the wrench in a natural horizontal unloaded state and press the "O/C" key to clear the existing displayed value, making the current state "zero".

测量：分为跟踪测值峰值测值预置测值

Measurement: divided into tracking measurement values, peak measurement values, preset measurement values

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）

Shutdown: Manual shutdown (automatic shutdown occurs when the wrench is not operated for two minutes)

自动关机（长按O/C键即可）

Automatic shutdown (long press and hold the O/C button)

后就是我们该如何读数了？

How should we take the readings after that?

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

If it is a torque instrument with a meter, directly read the data indicated by the pointer as the measured data value

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

If it is a sleeve plus sub scale indicator, the scale value on the main scale should be read first, and then the sum of the scale values on the sub scale or differential cylinder should be taken as the measurement 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 the usage method of torque wrenches. So when you understand torque wrenches, should you consider how to choose a high-quality torque wrench.
