How to transport the instrument in summer safely?

High temperatures above 30 degrees finally arrive at the “tail” of June! I believe many people have prepared various \"artifacts\" to protect themselves from the sun, cool down and relieve the heat, waiting to welcome this heat wave. Of course, the laziest way is to \"stay\" at home and enjoy air-conditioned WiFi watermelon without leaving the house. However, whether it is windy, rainy, or very hot or cold, many instruments and equipment must still work. You could say it’s “rain or shine”.
　
For those who have not been exposed to complex instruments, they may not understand that many instruments and equipment on the market often cost more than 100,000 million. However, these relatively expensive, precise and very sensitive instruments and equipment, especiallyulier measuring instruments, are also easily affected by various environmental factors. This is mainly because these instruments have a complex manufacturing process and use many components. Temperature, humidity, electromagnetic interference and other factors can easily affect these components, introducing instability factors. Therefore, the impact of various environmental factors on the instruments and equipment is considered while planning the construction of the computer room or laboratory.
　
　 Summer is hot and rainy, accompanied by thunder and lightning. How can our high precision instruments safely survive this hot summer and ensure their operation is not affected?
　
Remember to cool the instrument and avoid the “hot and cold”
　
As we all know, temperature is the mainipal factor among various environmental factors. Higher temperatures will impair the use of most precision instruments. Even within the specified operating temperature range, temperature changes will cause components made from various materials to twist and deform due to different expansion coefficients. In particular, some measuring instruments are prone to errors in the data, leading to distortion of the measurement results. This temperature change will also cause the parameters of the electronic components of the instrument to drift, affecting the test accuracy and the life of the electronic components.
　
Several points to note: ① When using instruments and equipment, the ambient temperature should be within the standard temperature range required by the instrument as much as possible, which can be adjusted by installing air conditioningatizer; ② The air conditioner should be installed in a place that is not too close to the equipment; ③ Reduce temperature changes caused by turning on and off air conditioners and frequent entry and exit of personnel; ④ Avoid temperature effects caused by direct contact of human hands with some small precision instruments.
　
High humidity is easy to corrode. Rapid dehumidification extends the life of the instrument

Laboratory researchers usually pay attention to various factors of the environment in which the instrument is located and make timely adjustments. However, many companies pay attention to temperature control during the production process, but ignore the subtle impact of humidity on instruments and equipment.
　
Some areas have rainy and humid summers, and indoor humidity caneasily be too high. When humidity is too high, the main impact on large instruments and equipment is corrosion. Metal parts and circuits of instruments and equipment will be corroded due to excessive humidity. In complex integrated circuits, electronic components not only corrode but are also prone to short circuits. Most instrument failures are caused by circuit corrosion resulting in poor contact or short circuit. If the situation is serious and it is not maintained and repaired for a long time, the instrument will not only reduce its accuracy, but its service life will also be greatly reduced.
　
Pay attention to a few points: ① Install dehumidification equipment and adjust the indoor humidity in time; ② Since the temperature of the laboratory in summer is lower than that outside, personnel entering and exitingnt will bring high temperature saturated water vapor from outside; water vapor adheres to the instrument. Small water droplets condense on the instrument, causing excessive humidity; Frequent entry and exit of personnel should be avoided as much as possible, and the humidity in the laboratory should be kept stable; ③ Human hands are prone to sweating in hot weather, so it is best to wear gloves to avoid direct contact with the instrument.

Pay attention to lightning protection during thunderstorms

There are many thunderstorms in summer, and once the instrument is struck by lightning, it will be fatal. The most harmful are direct lightning and induction lightning. A direct lightning strike will directly penetrate the electronic elements of the instrument and easily cause a fire. Induction lightning will invade power lines, causingnt the discharge of equipment, causing short circuits or even more damage.
　
 Some points to note: ① In order to prevent lightning current from entering the instrument and equipment, remember to cut off the connection between the instrument and the antenna, wire ground and power cord during lightning storms. ② Use lightning arresters, isolation transformers, filters and other equipment to prevent lightning circuit intrusion.
　
In addition, you should also pay attention to the cleanliness of instruments and equipment and remove dust and dust in a timely manner. Air filters or fresh air systems can be installed to freshen the air in the laboratory. Although some high-precision instruments are quite large, there are still many \"tricky\" moments. In order to maintain the normal operation of instruments and equipment and ensure the accuracy and stability pDuring this hot summer, we must pay more attention to them.
