1. Peak value: refers to the magnetic induction value of each pole vertex, in kGs (thousand Gauss), 1kGs=0.1T (Tesla). There are as many peaks as there are magnetic poles in the magnetic ring, with the positive peak representing the N pole and the negative peak representing the S pole.
2. Angle: refers to the degree of each magnetic pole vertex relative to the starting zero of the magnetic pole.
3. Area: refers to the area between the magnetic sensation waveform of each magnetic pole and the Angle coordinate, the unit is T degrees, that is: Tesla × Angle. Its physical meaning is expressed as the integration of the magnetic inductance over the Angle. The total area is the algebraic sum of the areas of all magnetic poles.
4. Width: refers to the number of degrees between the beginning and end zero of each magnetic pole.
5. Half-height width: refers to the number of degrees between the two 50% peak points of each magnetic pole.
6. Included Angle: refers to the peak Angle of each magnetic pole relative to the peak Angle of the previous magnetic pole.
7.08 Included Angle: refers to the number of degrees between the midpoint of the two 80% peak points of each magnetic pole and the same point of the previous magnetic pole.
8. Maximum, minimum, average, standard deviation: according to the mathematical definition, all N-poles and S-poles are calculated separately in the test report;
9. Cumulative error: For each parameter, calculated according to its maximum and minimum values, cumulative error =100× (maximum - minimum)/minimum.
