The calibration of all torque wrenches is performed on one of forty three certified testers, by qualified personnel. Each wrench will be tested over the full range of the tool, to comply with current specifications.
Each tool will be affixed with a sticker giving the date the wrench was calibrated. Space is provided for the customer to write in the recall date, for the tool to be recalibrated. Angle cannot do this for you since we do not know how often you will be using the tool daily, weekly, or once in a while.
