We often encounter the standard of protection level IP when determining many standards for instruments and meters. So what is the protection level and the numbers behind it? Here are some introductions for everyone to facilitate your reference and reference in your work. The protection level system IP (INTERNATIONAL PROTECTION) is drafted and formulated by the IEC organization. The system classifies instruments based on their dust, moisture and other characteristics. The IP protection level is composed of two numbers. The first number indicates the level of dust and protection against foreign objects from the instruments and appliances, and the second number indicates the degree of moisture and water resistance of the instruments and appliances. Large means higher protection level. ^[2]

   1.Percussion hand pressure method

   When we use the instrument, we often encounter the phenomenon of good and bad when the instrument is running. This phenomenon is mostly caused by poor contact or welding. In this case, knocking and hand pressing can be used.

   The so-called "knock" is to gently tap the plug-in board or component with a small rubber hoe or other percussion object to see if it may cause an error or a shutdown failure. The so-called "hand pressure" means that when a fault occurs, the components and plugs and sockets that are plugged in after the power is turned off are pressed again by hand, and the power is turned on to try to eliminate the fault. If you find that the casing is normal, and then it is abnormal, it is best to re-plug all the connectors and try again. If it is not successful, you have to think of another method.
