What is the use of thermal calibrator? The verification or calibration plan for measuring instrument equipment should begin with the source of equipment selection. When selecting instruments and equipment, laboratories should consider how to meet the needs of measurement uncertainty, including a complete set of control measures such as controlling the use environment, calibration cycle, cycle verification, authorized use, and normal maintenance to ensure that instruments and equipment can well meet the requirements. measurement requirements. For example, when it is confirmed that a 6½-digit digital voltmeter cannot meet the needs of laboratory testing and calibration work, the laboratory should purchase a 7½-digit digital voltmeter.

What is the use of thermal calibrator? Identify verification or calibration objects. Which instruments and equipment need to be verified or calibrated shall be considered by the laboratory according to the actual situation. All measuring instruments and equipment that affect the accuracy of detection and calibration, even auxiliary measuring instruments and equipment, should be included in the plan. Whether measuring instruments and equipment are verified or calibrated depends on whether they are included in the catalogue of measuring instruments administered by the state according to law. If they are listed, they will be verified, otherwise they will be calibrated.

What is the use of thermal calibrator? Determine the verification or calibration cycle. For the measuring instruments and equipment that need to be verified, the verification period is clearly specified in the corresponding metrological verification regulations. When determining the calibration cycle of measuring instruments and equipment, if there are provisions in the technical standards of the instruments and equipment, the standard requirements should be implemented, and it is stipulated that "equipment in normal use should be inspected once within a year"; The room can be considered from the technical characteristics of the equipment and the frequency of use. For the latter, the laboratory shall give the necessary approvals for the determination of the calibration period.

What is the use of thermal calibrator? Put forward technical index requirements. For the measuring instruments and equipment that need to be verified, the verification items and methods are clearly specified in the corresponding metrological verification regulations, and the laboratory only needs to put forward the requirements for the implementation of the metrological verification regulations. For measuring instruments and equipment that need to be calibrated, the laboratory should determine the technical indicators, including range, preparation level, etc. Test and calibrate as needed.

What is the use of thermal calibrator? Select a verification or calibration service facility. The verification or calibration plan developed by the laboratory should take into account that different measuring instruments and equipment can have different calibration methods, some can be internally calibrated and some can be externally calibrated. When performing internal calibration, it shall comply with relevant national regulations and be able to prove the ability to engage in calibration; the internal calibration method shall be documented, reviewed and confirmed, and the calibration personnel shall receive necessary training and obtain corresponding qualifications. The external verification or calibration service agency selected by the laboratory meets the following conditions: first, it is qualified; second, the measurement authorization range, recognized calibration capability or standard setting range can ensure that the measurement uncertainty can meet the use requirements of the measurement equipment.
