5. Diverse display solutions: Point to point, point to many, and multi to point LED screen data display solutions can be selected according to on-site needs
To determine whether the atmospheric negative oxygen ion monitoring device is malfunctioning, we can start from these aspects:
1、 Check if the data is abnormal
If the reading suddenly surges or drops sharply, or continues to fluctuate, it may be caused by sensor aging, expired calibration, or environmental interference (such as high humidity, strong electromagnetic fields). It is recommended to first check the calibration records, clean the sensor, and try changing the environment.
2、 Listen for any alarm prompts
Sensor malfunction: Continuous buzzing+flashing indicator light, possibly due to sensor contamination or damage.
Low battery: Short beep+flashing, reminding that it's time to charge or replace the battery.
System error: Yellow light on+beep, check if the power and signal lines are properly connected.
3、 Check the device status
Screen display: Black screen, blurred screen or garbled text, may be due to loose wiring or motherboard issues.
Alarm function: When placed in a known environment that exceeds the standard, if no alarm is triggered, it may be due to system failure or incorrect threshold settings.
