Description：
Convenient adjustment mode with supporting gear adjustment mode, suitable for construction environment.
Bolt torque comparison table mode, easy to find the right torque.
Gain adjustment function for quick adjustment of the in-position torque.
Extremely excellent power-to-weight ratio, wider torque range. Lighter and smaller.
Automatic reset anti-seize counteractive arm function for easier operation.
User (operator, administrator) hierarchical function management.
Support third-party intelligent proofreading torque, use software to adjust gain hardware compensation, extend tool life
The torque value of locking and loosening can be recommended according to the strength grade and size of the bolt, and the reference value can be modified to conform to the actual working condition.
The power supply voltage regulator unit and input voltage rectification feedback control function can restrain the fluctuation of power grid input voltage and improve torque precision.
Precision ±5%, repeatability ±2%.
Follow-up monitoring of tightening results (failed, success, uncompleted).
