- The spring testing machine TG 9 tests right and left-coiled torsion springs with a parallel digital 3.5-digit torque and 5-digit angular display. The angle is measured in 3600 steps per rotation; this corresponds to a resolution of 0.1 degrees.
- The spring testing machine has a data output for connection to a PC. The measurement values are calculated in a continuous process, and can be traced at any time via the saved spring core line.
- A commercially available printer with LPTCentronics interface can be used for protocol creation.
