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、扭矩可調(diào)扳手，是扳手的一種，目前市場(chǎng)上常見(jiàn)的有手動(dòng)扭力扳手，電動(dòng)扭力扳手，氣動(dòng)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.

而數(shù)顯扭力扳手顧名思義就是帶數(shù)字顯示的扭力扳手（扭矩扳手，力矩扳手），它有別于一般的扭力扳手，擁有強(qiáng)大的操作功能，包含扭力設(shè)定；單位設(shè)定；模式設(shè)定；數(shù)值儲(chǔ)存；數(shù)值；數(shù)值輸出以及網(wǎng)絡(luò)校正功能，數(shù)字扭力扳手，鉻釩鋼材質(zhì)。它是扭矩扳手中的一種，不但能夠當(dāng)施加的扭矩達(dá)到設(shè)定值時(shí)，扳手會(huì)發(fā)出“卡塔”聲響或者扳手連接處折彎一點(diǎn)角度，而且會(huì)通過(guò)數(shù)字顯示屏或者LED燈來(lái)提示使用者，而且在扭矩的設(shè)定上也能夠通過(guò)按鍵和數(shù)字顯示屏來(lái)完成，比之非數(shù)顯扭力扳手更方便也更易與操作?？偠灾?dāng)?shù)顯扭力扳手是扭矩扳手中更易于操作的，它通過(guò)安裝數(shù)字顯示屏降低了對(duì)操作人員的要求。（PS：來(lái)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)

我們來(lái)看扭矩扳手的分類(lèi)，扭矩扳手有指針式和預(yù)置式兩種，指針式的扭矩扳手使用方法很簡(jiǎn)單，在達(dá)到一定力矩之后指針就會(huì)指向相應(yīng)的數(shù)字，預(yù)置式扭矩扳手使用方法更簡(jiǎn)單，需要多大力矩就調(diào)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、旋下手把后端的電池蓋，正極朝前裝入 2 節(jié) 5 號(hào)電池，然后旋緊電池蓋；

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”鍵，開(kāi)啟電源，液晶顯示器字符全顯，扳手開(kāi)始自檢，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、單位選擇，按“▼”選擇所需的測(cè)量單位；

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

4、測(cè)量方式選擇：按“M”鍵，選擇“跟蹤 F”或“峰值 H”模式；

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

5、扭矩值報(bào)警預(yù)置：按“M”“預(yù)置 P”模式，再按“P”鍵確定所需預(yù)置扭矩值的位數(shù)，按 “▲”及“▼”鍵確定所需預(yù)置報(bào)警數(shù)值，預(yù)置結(jié)束后按“M”鍵退出預(yù)置模式，回到“跟蹤 F”狀態(tài)，或再按一次“M”鍵進(jìn)入“峰值 H”狀態(tài)。

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：在測(cè)量前將扳手處在自然水平空載狀態(tài)下，按“O/C”鍵現(xiàn)有的顯示數(shù)值，使當(dāng) 前狀態(tài)為“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、測(cè)量：分為跟蹤測(cè)值、峰值測(cè)值、預(yù)置測(cè)值

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

8、關(guān)機(jī)：手動(dòng)關(guān)機(jī)（當(dāng)扳手在兩分鐘未進(jìn)行任何操作會(huì)自動(dòng)關(guān)機(jī)）

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

自動(dòng)關(guān)機(jī)（長(zhǎng)按O/C鍵即可）

Automatic shutdown (long press O / C key)

就是我們?cè)撊绾巫x數(shù)了？

Is how we should read?

1、如果是帶表扭力儀器.直接讀取指針?biāo)甘镜臄?shù)據(jù)為測(cè)量數(shù)據(jù)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.應(yīng)先讀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為測(cè)量數(shù)據(jù)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，那么當(dāng)你了解了扭矩扳手，是不是該考慮一下如何去選擇一個(gè)質(zhì)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.
