Some require seven-step measurement outside the gate, while others require measurement at the intersection of two diagonal lines (the center of the house). No matter where the measurement is, its purpose is to find out the magnetic field of the house and determine the sitting direction of the house.
When measuring, make the compass in a horizontal state, and the crosshairs of the compass (Tianxin Ten Channels) face the gate horizontally and vertically to stabilize the magnetic needle. Then turn the compass so that the pointer of Tianchi points in the north-south direction, with the pointed end pointing south and the trumpet end pointing north. Then look at the crosshair perpendicular to the direction of the mountain pointed by the gate, with the gate facing outward and sitting opposite.
In addition, when using the compass, we should pay attention to the interference of various magnetic fields in the house, such as electrical equipment, switch boxes, pipeline wells and so on. , including mobile phones, will affect the direction of the magnetic needle. In addition, don't have too many people indoors when measuring. If possible, try to clear the area, especially children and small animals (cats, dogs, etc.). ), it has a greater impact on the magnetic needle.
