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 direction;
In the third step, turn the pressure gauge clockwise. When the vertical line is placed in the of the manometer, it is enough to find the scale value of the corresponding dial.
