Abstract

An angle measuring device or system can include a wrench and a digital angle meter. The wrench can include a head for engaging a fastening device, a central axis about which the wrench or bracket rotates during use, and a longitudinal axis perpendicular to the central axis. The digital angle meter can be attached to the wrench or bracket and include a housing, a processor, and at least one gyrometer. The at least one gyrometer including a first axis extending parallel to the longitudinal axis for determining the rotational orientation of the wrench or bracket relative to a reference position. A sensor of the digital angle meter allows for an automated and accurate calculation of a total angle of rotation of the nut or bolt about the central axis using a ratcheting wrench.
