<p>An angle measuring device or system (10) can include a wrench (12) and a digital angle meter (14). The wrench can include a head (16) for engaging a fastening device, a central axis (CA) about which the wrench (12) or bracket rotates during use, and a longitudinal axis (LA) perpendicular to the central axis. The digital angle meter (14) can be attached to the wrench (12) or bracket and include a housing (24), a processor (52), and at least one gyrometer (56). The at least one gyrometer including a first axis extending parallel to the longitudinal axis for determining the rotational orientation of the wrench (12) or bracket relative to a reference position. A sensor of the digital angle meter (14) allows for an automated and accurate calculation of a total angle of rotation of the nut or bolt about the central axis (CA) using a ratcheting wrench (12).</p> |
