experimental instrumentTraceability of equipment is one of the main means to ensure measurement accuracy. According to the requirements of laboratory qualification standards, instruments and equipment shall be verified or calibrated before use, and if necessary, interim verification shall be carried out between secondary verification or calibration to ensure the accuracy of data. However, some laboratories did not send the instruments to the measurement department for verification or calibration according to regulations, resulting in the misalignment of the instruments. Some verification/calibration laboratories issued certificates without verification/calibration.

At present, most testing instruments and equipment require intelligent interfaces supported by computer skills. It also shows that many electronic components need to be connected to VLSI chips, relays and other mechanical equipment. We all know that the more modules, the higher the failure rate of the instrument, and the reliability of the entire instrument is relatively reduced. The design of high-quality products should consider reliability and automatic protection functions (such as overload protection and protection), select high-quality, long-life and aging test components, and conduct strict environmental tests, vibration tests, and weather resistance tests before leaving the factory And other reliability type tests. Therefore, the operator can safely move the equipment and conduct field tests. In summary, when purchasing and testing instruments and equipment, the reliability of testing instruments should be understood, and on-site investigations should be conducted on manufacturers or suppliers (such as process design, production conditions, storage, transportation and manufacturer's factory inspection).

Let's take a look together.experimental instrumentUnder what circumstances will the equipment have adverse risks

1. Remember not to put together the experimental instruments and equipment that affect each other, because such experimental instruments will interfere with each other, resulting in inaccurate data.

2. Remember to do periodic verification of instruments and equipment, otherwise the performance cannot be supported and controlled.

3,experimental instrumentThe equipment shall be properly marked and not misplaced, otherwise it is easy to misuse.

If the equipment is not equipped with safety protection equipment, it will bring safety risks to the operators.

5. In the laboratory, gas cylinders are indispensable equipment and have great safety risks. Moreover, the gas cylinders are not stored in different categories and there are no fixed leak-proof facilities, so there is a hidden danger of explosion.

When designing the laboratory, we must pay attention to the design of the gas circuit in the laboratory. If the intersection is at sixes and sevens, there will be fire safety hazards.

In the Chinese laboratory, pay attention to the long-term use of experimental equipment, because it is prone to abnormalities and cannot be traced back. Allexperimental instrumentThe equipment shall be used frequently and recorded.

8. In the laboratory, it is necessary to back up the documents of instruments and equipment, which will bring trouble to maintenance.

9. This is very important, related to the health of laboratory personnel. someexperimental instrumentThe equipment needs to be equipped with a strong exhaust device to protect laboratory personnel.
