1. The Torque Wrench Calibration System is a high precision machine designed to measure and verify the calibration of hand torque tools Considered one of the most flexible and user friendly calibration systems available LSI s TWCS is offered in three models a Standard model TWCS Super model STWCS and an Ultra model UTWCS The TWCS model operates with one load cell on a single unit Select from five available torque capacities The STWCS features interchangeable smart torque cartridges Switch load cells easily when a different torque capacity is needed and enjoy the convenience For flexibility without changing out cartridges the UTWCS allows up to three stationary load cells to test hand torque tools of different capacities all on the same unit Instantly change torque capacities with the push of a button Available torque cartridge capacities range from 3 in lbs to 260 ft lbs depending on model In all models the load cells are protected during use by mechanical and software stops to safeguard from overload damage Each model includes three test modes Manual for needle indicating tools Peak for dial indicating or digital tools and First Peak for click type torque tools Unique to the industry the STWCS and UTWCS both feature an on screen Calibration Assistant program to guide the user through the calibration steps and print a certificate compliant with ISO 6789 standards Connect to any parallel printer with the RS232 cable and adapter
