How to use the torque wrench

How to use the torque wrench, torque wrenches are widely used in enterprises and laboratories, special tools for threaded fasteners with torque requirements. According to Shanghai Henggang technicians, many users of torque wrenches did not use and maintain according to requirements, resulting in large deviations in measurement data, exceeding the large tolerance of the Zui requirements.

Of course, the torque wrench can be extended by standardizing the correct operation of the torque wrench and standard maintenance management. So what should we do? What should I pay attention to when operating and maintaining the torque wrench?

Shanghai Henggang technicians reminded: Before using the torque wrench products, you must read the instructions carefully. The first thing to consider is the stability of the torque wrench, the sensitivity of the torque wrench, the correctness of the torque wrench and the invariance of the torque wrench. If you do not read the instructions carefully before use, it is easy to ignore the "calibration" operation, resulting in large measurement errors, so special care should be taken to protect them during use.
