Nonlinear node detection equipment performance parameters:

Maximum Probing Distance: The non-occlusion detection distance of the non-linear node detector to the PN junction is not less than 900mm.

With occlusion detection performance metrics:

1. The plastic case with a wall thickness of 5.5mm is used as a covering between the host and the PN junction. The host information display can be displayed when the device is 500mm away from the outer surface of the suitcase. A prompt signal appears.

2. The 200mm thick foam is used as the obstruction between the host and the PN junction. When the probe is 550mm away from the obstruction, the host information display screen can display a warning signal.

3. The device and the PN junction are covered with 100mm thick 70g A4 printing paper. When the probe is 500mm away from the obstruction, the host information display screen can display a prompt signal.

4. The equipment and the PN junction are covered with 200mm thick concrete, and the probe can display the prompt message on the other side to detect the host information display.
