A microprocessor-based system that provides accurate torque control when combined with torque control pulse tools. The system monitors the signals from the tool transducer and then makes decisions based on the parameters that you have programmed into the unit. The system provides a full set of visual, audible, digital and I/O outputs. Eight separate tightening strategies can be pre-programmed and select via line control or switches. The unit features strategies that help identify cross threading, double tightening and high or low torque. The controller also provides "Gang Count" and other advanced tightening strategies.
