The related accessories may include a vacuum pump, a vacuum pipe and a vacuum valve, etc. They are used to control, maintain and change the vacuum degree of the cavity. When using the cavity vacuum detection tool, you first need to connect the related accessories to the cavity, and then turn on the vacuum pump switch to extract the gas to make the cavity form a vacuum state. Next, use the vacuum detector to read the pressure in the cavity and convert it into a vacuum value. According to the measurement results, you can judge whether the vacuum degree of the cavity is To meet the requirements, if the vacuum degree is insufficient, the vacuum degree of the cavity can be changed by adjusting accessories, such as controlling the running time of the vacuum pump or opening or closing the vacuum valve, until the requirements are met.
