Calibration and Maintenance Operation Guidelines

　　1、Equipment inspection and testing

　　Before conducting equipment calibration and maintenance,a comprehensive inspection of the equipment is necessary.The inspection includes checking whether the appearance of the equipment is intact,whether the connecting components are tight,and whether the power supply is normal.At the same time,conduct necessary functional tests to ensure that the equipment is in normal working condition.

　　2、Standard reference source

　　During the calibration process,it is necessary to use a standard reference source as a benchmark to ensure the accuracy of the calibration.The selection of standard reference sources should follow industry standards and specifications to ensure their accuracy and stability meet calibration requirements.

　　3、Calibration process

　　Determine calibration items and methods based on equipment type and calibration requirements.

　　Use standard reference sources to calibrate the equipment and record calibration data.

　　Analyze calibration data to determine if the equipment meets the predetermined requirements.

　　If the equipment does not meet the requirements,it needs to be adjusted or repaired,and recalibrated.

　　4、Calibration records

　　During the calibration process,detailed records should be kept of calibration data,calibration results,calibration personnel,calibration time,and other information.Calibration records should be well preserved for future reference and analysis.

　　5、Preventive maintenance

　　In order to extend the service life of the equipment and maintain stable performance,preventive maintenance is necessary.Preventive maintenance includes regular cleaning of equipment,checking for loose or worn equipment components,and regularly replacing vulnerable parts.

　　6、Responsive maintenance

　　When equipment malfunctions or performance declines,responsive maintenance needs to be carried out in a timely manner.Responsive maintenance includes fault diagnosis,troubleshooting,equipment repair,etc.During maintenance,attention should be paid to safe operation to avoid secondary damage.

　　7、Maintenance records

　　Whether it is preventive maintenance or responsive maintenance,detailed information such as maintenance content,maintenance time,maintenance personnel,and maintenance results should be recorded.Maintenance records help analyze the causes of equipment failures and improve equipment maintenance efficiency.

　　8、Performance evaluation

　　Regularly evaluating the performance of equipment helps to understand its operational status and identify potential issues in a timely manner.The performance evaluation includes aspects such as equipment accuracy,stability,and reliability.Based on the evaluation results,develop corresponding maintenance plans to ensure the continuous and stable operation of the equipment.
