Note ①: The test signal is a single pulse, after overshooting, the sensor will enter the self-recovery state, the status indicator will go out, and it will take about 50ms to return to the normal working state.
Note ②: The ppm data refer to the IPN corresponding to the fullness of the secondary output signal.
