① Pressure control treatment is required for the calibration gas, and the pressure entering the instrument should not exceed 0.05MPA;

② The output pressure of the standard gas secondary meter shall not exceed 0.30MPA;

③ All gas pipelines entering the instrument have undergone strict leak checks, and this work is carried out every six months during normal operation of the instrument;

④ Before entering the instrument, the air path passes through a physical filter with a capacity of 10u. If air resistance is found, the filter screen (filter) can be checked first;

⑤ Regularly clean the fan filter of the analyzer, once every quarter; The environment is harsh and requires frequent cleaning to prevent instrument overheating caused by poor ventilation;

⑥ The installation location of the instrument should be horizontal and away from the vibration source; To prevent errors caused by uneven sample convection due to detector unevenness;

⑦ The surrounding environment of the analyzer requires good ventilation, and enclosed spaces should be avoided to prevent measurement errors caused by uneven oxygen levels;

⑧ Avoid flammable gases around the analyzer, as this can seriously affect the accurate measurement of the detector;

⑨ Due to the high temperature operation of the detection, if the gas to be tested contains H2, CO, CH4, this substance will react with oxygen, consume some oxygen, reduce oxygen concentration, and cause measurement errors. Therefore, instruments should consider this factor when measuring gases containing flammable substances to avoid measurement inaccuracies. In this case, it is necessary to choose an oxygen and combustible gas zirconia analyzer, not just an oxygen gas analyzer.

⑩ When measuring corrosive gases, corrosion-resistant metal probes such as nickel chromium alloy probes should be used.
