How the digital torque wrench outputs the torque value
Digital torque wrenches usually have a digital display that directly displays the current torque value. The user can set the desired torque value via the buttons or knobs on the wrench. When the torque reaches or exceeds the set value, the digital torque wrench will have different feedback methods, such as audible alarm, vibration or light indication to alert the user.

The basic steps for the output torque value of the digital torque wrench are as follows:
1.*Set the desired torque value**: Turn on the wrench and set the desired torque value via the buttons or knobs on the wrench. This value is usually determined based on the size and tightening requirements of the bolt or nut.
2.*Start Tightening**: Align the wrench with the bolt or nut to start rotating the wrench. The wrench measures and displays the current torque value in real time.
3.*Feedback when set value is reached**: When the torque of the wrench reaches a preset value, the wrench will alert the user with an audible alarm, vibration or light indication.
4.*Stop Tightening**: Once the desired torque value is reached, the user should immediately stop rotating the wrench to avoid exceeding the torque limit.
5.*Confirm Output Torque Value**: If required, the user can check the torque value on the digital display to confirm that the set torque has been reached.
Some advanced digital torque wrenches also have data logging and output functions, which can output torque values to a computer or other equipment for analysis or recording. This is usually achieved via a USB connection or wireless transmission function.
The use of a digital torque wrench can improve the accuracy and efficiency of tightening operations and reduce the risk of bolt or nut damage due to improper torsion.
