Such as: the large-scale conductor influencing the electromagnetic field is avoided as much as possible, and shielding measures are also adopted as much as possible, which cannot be avoided; when the AC-DC power supply converter works, an electromagnetic field is formed around the AC-DC power supply converter, the distance between the AC-DC power supply converter and a measured object is strictly kept, and the distance, the height and the angle kept each time are strictly consistent; the specification and the length of the power line used each time are completely the same.

In the traditional test process, the placing height of the power converter is generally only visual, and the power converter is not consistent in height and is not regulated by a professional device which can be lifted freely, and is generally very inconvenient to use by adding or removing the padded objects; the distance control of the tested product and the power converter can only be based on straightening a direct current power line with a specific length, and the fact that the placed height and the placed position of the power converter are inconsistent during each measurement often occurs, so that the electromagnetic interference of the power converter is different each time, and the test comparison result is affected.
