1. If the user is not familiar with the instrument, it is prohibited to disassemble or replace the gas detector at will. Before leaving the factory, calibrate the gas. If replaced, please recalibrate. If there are any issues, they should be operated under the guidance of personnel.

2. Gas detectors should avoid the impact of high concentration gases, making the detector prone to poisoning; Frequent power outages and unstable power supply should be avoided, which can easily damage the instrument. Regularly wipe the detector to prevent dust from blocking the sensor.

3. Gas detectors should be calibrated regularly: the gas detector should be calibrated to prevent the detection data from drifting and improve the accuracy of the detector data. Regular calibration of detectors, protection of components, and long service life. According to the on-site testing environment, detector calibration is generally used after one or six months.
