1. The pressure calibration table implements the principle of "dedicated personnel responsible, prevention oriented, frequent maintenance, and timely repair". The maintenance, upkeep, debugging, and minor repairs of the pressure calibration table are the responsibilities of the experimenter.

2. Daily maintenance: refers to the routine maintenance carried out according to the operation and management regulations of the pressure calibration table. The main projects include external cleaning, lubrication, fastening, and visual inspection of the instrument.

3. First level maintenance: This project involves entering the interior of the equipment from the outside (global cleaning, lubrication, and fastening). It mainly includes local disassembly inspection and adjustment of the pressure calibration table that can be disassembled for general maintenance (such as dismantling the shell), as well as power on trial operation or moisture removal of the entire pressure calibration table.

4. Second level maintenance: This project mainly refers to the internal maintenance of the pressure calibration table, which mainly includes the disassembly or non disassembly inspection and adjustment of the main components of general detachable instruments, replacement of vulnerable parts, and also includes the re counting and combination of all supporting components in the complete pressure calibration table, and replacement of vulnerable parts. In addition, it also includes precision inspection, calibration, and calibration of various pressure calibration tables that have been in use for more than three years. Keep the pressure calibration table in a clean, lubricated, safe, and usable technical state regularly.

5. Without affecting work, it is necessary to regularly maintain and upkeep the pressure calibration table under one's management. In addition to daily maintenance, a first level maintenance of the main instruments should be carried out once a month. Instruments with strict requirements for cleanliness, temperature, and humidity (including special drugs, animal and plant specimens, etc.)
