Driving mode: precision lead screw, not gear wheel Micro-computer controls, LCD displays data, results and curves. Professional software supports, controlled by microprocessor in all process of testing. Each function worked independently, standard unit, free form manual intervention. Analyzes group of specimens shows the arithmetic average, maximum, minimum. Menu interface, shortcut for selecting test, and easy to learn, master, and operate. Print out results, including stretching rate, maximum pulling, stiffness an flexibility. High performance DC servo-system, adjust speed by servo-system, working quiet, stability and reliability. Parameters stored permanently while power down and protection for over-load. Standard ink-jet printer prints out test reports. Energy-saving, stillness running, high performance and low cost.
