The structure of the control main board 107 and the tester host 1 and the detection principle of the photovoltaic cell are all prior art, and this application will not repeat them. After the detection is completed, release the test button 2, and the force of the spring 203 pushes the test button 2 to reset, so that the second contact 106 is separated from the first contact 105, and the support rod 202 releases the pressure on the normally closed contact switch 3, so that the normally closed contact switch 3 is reset and closed.
