Possible causes and solutions for the malfunction: If the power light does not turn on and the battery is dead, please charge the instrument in a timely manner. If there is no response, the sensitivity may be low. Re calibrate or replace the sensor. If the sensor fails, replace the sensor and the alarm indicator light will turn on. If there is gas in the environment, find the leakage point. If the potentiometer angle is incorrect, readjust the knob.
