Solutions to common faults of carbon dioxide detectors
1. The working time of the carbon dioxide detector is insufficient, and the measured data is inaccurate. At this point the detection time should be set.
2. The power supply is insufficient or the battery has reached the end of its service life. Check the charging source to ensure that the charging source has good contact, or replace the battery in time if the battery cannot meet the testing requirements. During the maintenance of the instrument, the model, specification and parameters of the components in the original circuit cannot be changed without authorization. The original packaging cannot be changed at will. All maintenance work of the carbon dioxide detector must be carried out by professionals. If the user cannot repair the instrument by himself if there is a failure during the use of the instrument, it should be returned to the factory for repair or replacement.
3. When the carbon dioxide detector has a silent alarm or a poor contact of the alarm or a circuit failure. Solder joints, wires and circuits and other devices should be checked in time.
4. The digital tube used in the instrument is damaged or the welding is loose. It is necessary to replace the digital tube or repair welding in time.
5. The excessive measurement error of the carbon dioxide detector during the detection process is mainly caused by the following reasons. The instrument is in a CO2 gas environment when it is turned on or calibrated, the power supply of the instrument is insufficient, and the alarm instrument drifts.
The above are the faults that are more likely to occur during the use of the carbon dioxide detector. When the instrument fails, it should be checked in time to ensure that the carbon dioxide detector can continue to be used in the follow-up work.
