thirdly, rotating the second hand wheel (52) to adjust the yaw angle of the second testing part (2) to a preset value, wherein the scales of the angle scale (311) correspond to the east-west, south-north directions of the geographic position, the third testing part (3) is not changed after being placed, and the sequence of the second step and the third step can be changed;
fourthly, the switch circuit module is turned on to supply power to the motor (121), the installation cavity (11) and the motor (121) are driven to rotate synchronously through a shaft, the geomagnetic module to be tested in the installation cavity (11) also rotates synchronously, and the geomagnetic module rotates to test preset time to power off the motor (121);
fifthly, the computer is connected with the Bluetooth module on the outer wall of the second balance ring (152), the test data stored in the data storage circuit is transmitted to the computer through the Bluetooth module, and the test data is analyzed by the computer;
and sixthly, repeating the first step to the fifth step to obtain a plurality of groups of test data.
