1. Check the gas flow rate, usually 30/h, if the flow rate is too large or too small, it will have a great impact on the results of the analyzer
2. Replace the filter paper: stop the air pump and drain the filter tank
3. Check whether there is air leakage in the air system. Whether the sobbing pump diaphragm is damaged, whether the sealing ring of the sampling probe is broken, whether the four-way valve and condensing steam are damaged, etc.
4. Clean the sampling probe and unblock the sampling hole pipeline
5. Check whether the condenser works normally, usually the temperature is adjusted within 3 degrees Celsius
6. Check the measuring chamber to see if it is dirty and clean it in time.
