Whether in industrial production, medical treatment, scientific research and many other fields, accurate detection of oxygen concentration is a crucial aspect. Otherwise, once the reading of the oxygen detector deviates, it may cause serious consequences and even threaten people's lives. Therefore, we must pay attention to the calibration steps of the oxygen detector to ensure the accuracy and reliability of the oxygen detector, to ensure that it can play its due role in various occasions, and to protect people's lives and property.

Calibration steps for the oxygen detector:

1. Boot warm up:

Turn on the oxygen detector and warm it up. According to the requirements of the instrument manual, it usually needs to be warmed up for a period of time to reach a stable state.

2. Enter calibration mode:

Depending on the model of the oxygen detector, it may be necessary to enter the calibration mode according to a specific key combination or sequence of operations. For specific operation, please refer to the user manual of the oxygen detector.

3. Set the calibration parameters:

According to the instructions of the oxygen detector, set the corresponding calibration parameters, such as calibration gas concentration, calibration gas flow rate, etc.

4. Pass calibration gas:

Pass the standard gas into the oxygen detector through the calibration pipeline, and adjust the flow controller to make the flow of the calibration gas meet the requirements.

5. Wait and read the concentration value:

Wait for a period of time and read the oxygen concentration value after the reading of the oxygen detector is stable. The read oxygen concentration value is compared with the concentration value of the standard gas to calculate the error value.

6. Adjust the calibration parameters:

If the error value is large, adjust the calibration parameters of the oxygen detector according to the error value until the error value reaches the specified range.

7. Repeat calibration:

Repeat the above steps until the measurement results of the oxygen detector meet the specified accuracy requirements.

8. Record Results

span> Record the calibration results of the oxygen detector in the oxygen detection calibration record sheet, includes information such as calibration date, calibration personnel, pre-and post-calibration concentration values, error values, and adjusted calibration parameters.

9. Exit calibration mode

After completing the calibration, exit calibration mode according to the instructions of the oxygen detector and restart the oxygen detector to apply the new calibration parameters.
