Working Principle
A Dip Circle works by allowing a magnetic needle to rotate freely in a vertical plane. When users place the instrument in the magnetic meridian of the Earth, the needle aligns itself with the Earth’s magnetic field. The angle formed between the needle and the horizontal plane is the dip angle. Users read this angle directly from the circular scale. The stable base and spirit level help keep the instrument aligned for accurate measurement.
