The dust cover 2 is made of transparent acrylic material. One end of the support column 3 is in contact with the inner wall of the upper side of the dust cover 2. A computer connection block 7 is provided at the upper end of the inner wall of the other end of the support column 3. The oscilloscope 5 is designed for single use. Instrument displays 8 are provided on both sides of the bottom of one end of the operating base 1. Multiple sets of buttons are provided at the position of one end of the operating base 1 above the instrument displays 8.

[0024] In this embodiment, through the usage settings of the above-mentioned device, electricity can be connected to the relay, and the relay is then connected to the pin 9.

At the same time, the operator places the main body of the washing machine circuit into the device, presses the button, and automatically tests. The operator only needs to check whether the test software is PASS or FAIL. In addition, this invention tests two boards simultaneously, with a test time of about 90-100 seconds, which can ensure both data stability and efficiency.

[0025] Example 2
