Method for setting tension value of electronic tension device:
Zhang Lizhi's size is determined by the resistance of the internal electronic device to the balance of the external tension spring.
(1) adjusting knob to adjust the spring 3 spring adjustment knob and 8 position of the tension spring;
(2) on the tension device through the wire, the winding wire, rotating 7VR1 tension adjustment knob, so that tension is in line with the requirements (clockwise tension becomes small, counterclockwise tension becomes large);
(3) if the tension is too large: you can rotate the 3 spring tension adjustment knob to reduce the spring tension, thereby reducing the output tension;
The 7VR1 tension adjusting knob can be rotated in a clockwise direction to reduce the output tension; if the tension is too small, the knob can be adjusted.
