Patent ID: 8713986

Claim:
A method for applying an electronic torque wrench calibration device, the method comprising: inserting a driving head of the electronic torque wrench into a driving member of the electronic torque wrench calibration device, wherein one end of the driving member is driven by the electronic torque wrench, and the other end of the driving member is pivotally connected to a base of the electronic torque wrench calibration device: driving the driving member to overcome a predetermined resistance against a pivotal rotation, thereby rotating the driving member, wherein the predetermined resistance is provided by a torque setting member of the electronic torque wrench calibration device which disposed on the base; checking if a torque value of the electronic torque wrench is the same as the predetermined resistance of the electronic torque wrench calibration device; and checking if a pivot angle value outputted by the electronic torque wrench and an angular scale markings indicated on a dial plate are the same, wherein the dial plate is pivotally disposed on a surface of the base and linked with the driving member, the dial plate comprises a plurality of angular scale markings located on a surface of the dial plate.
