Therefore, we usually use the measurement of four weeks (vertical line at 2/4/8/10 o'clock) to understand the beat value of the racket. How to use: In the first step, rotate the disc counterclockwise to zero the scale; In the second step, the two small cylinders of the pressure measuring device are perpendicular to the surface of the racking surface and inserted in the cross direction; In the third step, turn the pressure gauge clockwise. When the vertical line is placed in the arrow of the manometer, it is enough to find the scale value of the corresponding dial.
