Precautions for using carbon dioxide detector
1. Do not install the carbon dioxide detector in an environment with excessive gas concentration such as smog, jet insecticide (evaporator), flammable solvent (paint), otherwise it will cause an alarm when no carbon dioxide gas is detected.
2. Try not to use the carbon dioxide detector in places with high wind speed and flow, such as exhaust outlets and ventilation fans, because they will affect the measurement accuracy of the instrument.
3. The carbon dioxide detector cannot be used in an environment with a lot of water vapor or humidity (relative humidity is 90%). If it is used in this environment for a long time, the sensor may be damaged.
4. Avoid long-term use of the carbon dioxide detector in places where the ambient temperature is below -30°C or above 50°C.
5. Avoid using the carbon dioxide detector in an environment with strong electromagnetic.
6. When the carbon dioxide detector sends out an alarm signal, the control signal will be locked at this time. Even if the gas concentration has returned to normal at this time, the instrument cannot automatically return to the state before the alarm. At this time, it is necessary to reset or self-check the instrument .
7. After the carbon dioxide detector sends out an alarm, it is not allowed to turn on the electrical switch. The reasons for the excessive carbon dioxide concentration should be clarified first, and countermeasures should be taken in time.
8. If the carbon dioxide concentration of the instrument has exceeded the alarm concentration when the alarm is issued, the cause of the excessive carbon dioxide concentration should be eliminated before reusing the instrument, and then reset the instrument to clear the alarm data.
9. When the carbon dioxide detector is powered off for a period of time, it may sound an alarm when it is used again, which is a normal phenomenon.
10. After determining the detection position of the carbon dioxide detector, do not move its position casually to avoid damage to the accessories of the instrument.
In the process of using the carbon dioxide detector, the correct operation method should be adopted, and some usage matters need to be paid attention to, so as to ensure that the measured value is accurate, and the instrument can quickly send out the alarm function, which plays a good early warning and protection role for the on-site staff. effect.
