A split beam torque wrench comprising:
- a wrench body;
- a wrench head including a workpiece engaging portion, said wrench head being pivotally secured to a first end of said wrench body at a pivot joint;
- a handle located on a second end of said wrench body;
- said wrench body having a main beam extending from said first end to said handle and an anchor beam extending from said first end and terminating at an end separated from said handle;
- a catch pivotally connected to said main beam and releasably connected to said anchor beam;
- a torque setting screw threadably received in said handle such that rotation of said torque setting screw in a first direction biases said main beam away from said anchor beam and rotation in a second direction biases said main beam toward said anchor beam;
- an accelerometer or gyro operatively connected to a microcontroller;
- an input interface mounted on said handle;
- an electronic display operatively connected to said microcontroller;
- said microcontroller configured to received acceleration data from said accelerometer or gyro and angle of rotation input data from said input interface, and to output result data to said electronic display and sound instructions to said electronic audio output device.
