An advanced handle that can be connected to the standard STwrench smartHEAD to create a wrench that can be connected to the STa 6000 using a standard Atlas Copco transducer cable. The MRTT-C connected to the STa 6000 can be used to detect the residual torque using the advanced Torque/Angle algorithm.
