The 3-dimensional Hall probe composed of three planar hall sensors is a popular method to measure magnetic fields with high precision.But the non-alignment and non-orthogonality between the three hall sensors will influence the accuracy of the magnetic field measurement
and must be calibrated in advance.Various types of periodic magnetic fields provided by EPU 100
a variable elliptical polarizing undulator of APPLE-II structure at Shanghai Synchrotron Radiation Facility(SSRF)
was used to calibrate the non-orthogonality between the three hall sensors of a 3D hall probe.In this paper
we describe the method and the procedure of the calibration in detail.
