1. Pay attention to protect the front diaphragm and the compensation circuit board at the back end of the pressure core body, so as not to damage the performance of the pressure core body or cause damage to the core body.
2. Do not press the metal diaphragm with hands or hard objects to avoid core damage due to chip deformation or perforation.
3. The ventilation pipe at the rear of the g-core should be connected with the atmosphere; water, water vapor or corrosive media are not allowed to enter the reference chamber at the rear of the core.
4. Avoid falling and bumping, which will affect the stability of the product.
5. If there is any change in the pin lead, the label carried by the core shall prevail.
