An electronic torque apparatus equipped with an automatic compensation device with output torque includes an electronic torque wrench (100) with a changeable drive head (200), a plurality of drive heads (200) at varying lengths and an automatic compensation device in the electronic torque wrench (100) with built-in output torque. One of the drive heads (200) is selected to be installed on the electronic torque wrench (100) as desired. Through the automatic compensation device, compensation is set and calculated according to the type or length of the drive head (200) so that operation torque of the electronic torque wrench (100) and preset target torque are equal to actual output torque of the electronic torque wrench (100). Thereby users can directly and instantly get the actual output torque on a display element (150) without calculation or conversion through tables to improve reliability and usability |
