Performance test report  
1. Test purpose  
  Through the analysis of the test results, the evaluation of the product performance is obtained;
Evaluate whether the test product meets the technical requirements;
Provide reference data for product design and after-sales service, and provide a strong basis for leaving the factory.

2. Basic information

                Product model: DXWD-60
                Product Name: Electromagnet
                Test time: June 27, 2023
3. Testing environment  
  The detection environment is closer to the actual environmental conditions used by the user, including factors such as lead wire length and ambient temperature. The time is selected in the time interval where the fluctuation of the geomagnetic field is small. Before the test, the instruments required for the test were turned on and warmed up in advance and the measurement environment was recorded, as shown in Table 1.
