Embodiment 1

[0047] This embodiment is to perform static precision detection on the absolute angle sensor.

[0048] according to Figure 3 to Figure 6 Install the detection device in the connection mode shown, select the corresponding coupling and angle sensor mounting plate, and install the measured angle sensor on the corresponding mounting plate. Connect the appropriate data cables. Since the static accuracy test is performed in this example, it is necessary to connect the measured angle sensor to the output shaft decelerated by the worm gear. Since the absolute photoelectric encoder is selected for testing in this example, there is no requirement for the level or measurement method, so the detection device can be placed in any of the two placement methods, such as Figure 4 Placement as shown in , or flip the device 90 degrees along the A-A space.

[0049] Corresponding parameters are set on the industrial computer equipped with the special software of the present invention, such as...

Embodiment 2

[0057] This embodiment is to detect the dynamic accuracy of the planar electronic compass.

[0058] according to Figure 3 to Figure 6 Install the detection device in the connection mode shown, select the corresponding coupling and angle sensor mounting plate, and install the measured angle sensor on the corresponding mounting plate. Connect the appropriate data cables. Since the dynamic accuracy test is carried out in this example, and the electronic compass does not have high requirements for high-speed performance, the low-speed output shaft decelerated by the worm gear can be used for detection. Electronic compass accuracy detection needs to keep its level, so choose a horizontal detection plane (vertical output axis), such as Figure 4 For the installation method shown, use the leveling mechanism for leveling.
