Features
• Controlled by microcomputer, large-screen LCD display.
• With data storage function when power off, query up to 300 groups data, and print out test report in English.
• “zero” position is detected by optocouple sensor to avoid “zero” shift caused by Hall sensor.
• Right sample grip is derived high-performance direct-drive stepper motor, rotational speed can be
arbitrary preset to avoid the problems of brush wear and spark interface which is caused by DC motor.
• Can be pre-tensioned in the horizontal direction.
