數(shù)顯式扭力扳手
Digital display torque wrench
優(yōu)點：LCD視窗讀數(shù)，多種工作模式切換（峰值、跟蹤），多種單位切換（N.m、ft.lb、in.lb），頭部棘輪頭根據(jù)分為可更換和不可更換兩種系列，預(yù)設(shè)數(shù)值聲光報警，受力時扭矩值可實時觀察，常見的扭力檢測用扳手，精度在±1%左右，有些附帶數(shù)值存儲wifi連接打印功能。
Advantages: LCD window reading, switching of multiple working modes (peak value, tracking), switching of multiple units (N.m, ft.lb, in. lb), head ratchet head can be divided into replaceable and non replaceable series according to brands, preset value audible and visual alarm, torque value can be observed in real time when stressed, common wrench for torque detection, with an accuracy of about ± 1%, and some brands have the value storage wifi connection printing function.
缺點：價格相對較高
Disadvantages: relatively high price
使用方法：由于數(shù)顯扭矩扳手是高精度數(shù)字扭矩測量工具，扳手內(nèi)部都是電子元件，跟預(yù)置式機械扳手有很大區(qū)別，使用時需輕拿輕放。通常需要充電或者安裝電池使用，面板的按鍵功能使用也因廠家不同而有區(qū)別。同樣的，主要功能都差不多，使用也不復(fù)雜，具體操作可查看扳手配套的使用說明書。
Usage: As the digital torque wrench is a high-precision digital torque measuring tool, and the wrench is internally made of electronic components, it is very different from the preset mechanical wrench, so it should be handled with care. It is usually necessary to charge or install batteries for use. The use of key functions on the panel varies from manufacturer to manufacturer. Similarly, the main functions are almost the same, and the use is not complicated. For specific operations, please refer to the operation manual of the wrench.
The above is a detailed introduction to the price of the wrench, and I hope it will be helpful to you. If you have any questions, please contact us. We will provide you with professional services http://m.lvhe888.com
