An electronic torque-tool tester ( 10 ) designed to verify that various mechanical, electrical and pneumatic torque tools such as a torque wrench, are correctly calibrated. The tester ( 10 ) includes a housing ( 50 ) that is bordered by a horizontal mounting plate ( 14 ) and a vertical mounting plate ( 36 ). From the front of the housing ( 50 ) extends a torque transducer ( 132 ) that converts a rotational mechanical force produced by the torque wrench, into a corresponding electrical signal ( 11 ) that is converted by an electronics circuit ( 130 ) into a corresponding display signal ( 17 ). The display signal ( 17 ) operates a digital display unit ( 146 ) from where the applied torque in inch/pounds or foot/pounds can be viewed. The digital display unit ( 146 ) is attached to an articulated display assembly ( 108 ) that can be rotated through a 90 to 350-degree arc and that allows the digital display unit ( 146 ) to also be rotated through a 90 to 350-degree arc. Thus, allowing the tester ( 10 ) to be placed in an optimum position to view the applied torque.
