Battery: 9V 6F22 Battery x 1 (Not Included) Voltage Parameter How to Use 1. Follow the manipulation guide or the guidance of a professional. 2. Keep the digital display clean and the screen bright and clear to ensure easy visibility of pressure, temperature, and other numerical values. Regularly clean the display Cover and copper joints with a cleaner or soapy water. 3. Pressure gauges are vulnerable components and should be periodically calibrated by the metrology department to ensure accuracy. 4. Handle with care to prevent impact and falling. 5. After use, turn the knob to the OFF position to prolong the valve core's lifespan. 6. When not in use, it is recommended to seal the joints of the pressure interface to prevent foreign objects from entering. Regularly blow and replace the freezing medium pipe, and clean the valve body of dust and impurities. Package List 1 x Digital HVAC
