1、 Overview

Magnetic metal analyzer is a specialized instrument for measuring the magnetism and magnetic properties of materials, widely used in various industries and fields such as steel, machinery, power, chemical industry, etc. When using a magnetic metal measuring instrument, it is necessary to ensure its accuracy and reliability, so regular calibration is essential.

2、 Verification process

1. Preparation before verification: Before verification, the magnetic metal measuring instrument must be visually inspected and functionally tested to confirm that the instrument is intact and functioning properly.

2. Verification items: Magnetic coefficient, current, induced voltage, magnetic field strength, reaction time, and other items need to be verified, and the verification should be strictly operated in accordance with relevant standards.

3. Verification method: The verification methods for magnetic metal measuring instruments are mainly divided into two types: standard part method and non-standard part method. The standard part method is suitable for magnetic metal measuring instruments with high magnetization, good stability, and high verification accuracy, while the non-standard part method is used to verify magnetic metal measuring instruments with low magnetization, poor stability, and low verification accuracy.

4. Verification conclusion: After verification, the magnetic metal measuring instrument needs to be evaluated, and the evaluation results should be recorded in the verification certificate.

3、 Relevant standard requirements

1. The calibration of magnetic metal measuring instruments should comply with the requirements of relevant standards such as GB/T 34211-2017 "Technical Specification for Calibration of Magnetic Metal Measuring Instruments".

2. Verification should be carried out by professional technicians, and the verification results must be certified by recognized verification institutions to ensure the accuracy and reliability of the verification results.

3. Regular calibration should be conducted, and the calibration cycle should be determined based on factors such as usage environment, frequency, and importance.

4、 Usage management

During normal use, the magnetic metal measuring instrument needs to undergo regular standard calibration and verification to ensure the accuracy and reliability of its measurement results.

2. When storing instruments, attention should be paid to moisture, shock, and dust prevention, and prolonged storage in high, low, or humid environments should be avoided.

During use, it is necessary to avoid severe vibrations and collisions to avoid affecting its measurement accuracy and stability.

If it is necessary to repair and maintain the instrument, it is necessary to follow the requirements of the user manual and operation manual, and strictly follow the prescribed procedures.

【 Conclusion 】

The calibration of magnetic metal measuring instruments is an important step in ensuring the accuracy and reliability of their measurement results. Only by following strict calibration procedures and standards can the stability and accuracy of the instrument be ensured. When using and managing magnetic metal measuring instruments, regular calibration and maintenance are required to ensure their long-term stability and reliability.
