The auto reversing run down adapter (AURA) is engineered to provide consistent and reliable torque readings when testing power driven torque control tools with a torque tester or torque sensor. The run down adapter is mounted in-line between the tool drive and the transducer. The device reduces the impact and irregular peaks that cause poor repeatability.
The AURA is designed to only operate in a clockwise direction. Apply torque until the power tool shuts off. Then the AURA automatically unwinds for the next run down. Eliminating the need to back it out.
