Designed for notebook computers, tablet PCs, e-books, computer keyboards, etc., long side, short side of the whole machine to do twisting test, but also for a variety of spindles HINGE for torque (torque attenuation), life test, can be measured each time the torque value of the forward and reverse rotation, and through the USB2.0 communication module will be captured by the torque signal to the PC, by the PC to automatically record the curve of its curve changes and draw the torque attenuation life curve graph, the Windows® window screen to set the test conditions, easy to operate and all data can be stored (test conditions, torque-angle curve graph, life curve graph, test data report...) Using Windows® window screen to set up the test conditions, the operation is simple and convenient, and all the data can be stored (test conditions, torque-angle curve, life curve, test data report, etc.), which is a powerful tool for HINGE manufacturers to improve the quality of their products.
