Sturtevant Richmont Exacta 2 Digital Torque Wrench Description: Bi-directional accuracy of +/- 1% to 100% of capacity in Track and Peak modes meets or exceeds requirements of ASME B 107.300-2010 and ISO 6789. The Residual mode assists the user in determining retained Torque on a Joint. The accuracy percentage is contingent upon condition and user technique. Programmable Limits and a Yellow/Green/Red illumination system guide you as you use the Wrench. The display and a raised lens on the back of the Wrench illuminate when each significant Torque value is reached. An LED provides a Yellow/Orange light as you approach the minimum specification. The light turns Green when you reach the minimum Torque, and remains green until you either stop pulling on the Wrench or the maximum Torque specification is attained. If you overtorque, it turns bright Red to let you know. Just pull to Green! Audible prompts from a beeper supplement visual information.
