PROBLEM TO BE SOLVED: To position an inclined three-axis magnetic field sensor in a measurement space.SOLUTION: A first point 52 and a second point 54 having an equal distance with a first reference point 44 sandwiched are set on a first straight line 48 in a measurement space. Next, a third point 56 and a fourth point 58 having an equal distance with a second reference point 46 are set on a second straight line 50. A three-axis magnetic field sensor is moved to a position on the first straight line 48 where the absolute value of a three-dimensional measurement magnetic field vector measured by arranging a magnet at the first point 52 is equal to the absolute value of a three-dimensional magnetic field vector measured by arranging a magnet at the second point 54. The similar operation is also performed on the second straight line 50. Then, the three-axis magnetic field sensor is positioned on a straight line going on the first reference point 44 and the second reference point 46. |
