Packaging Specifications: • Sensor body *1, Food-grade silicone sealing ring *2. App Download: • iOS: Search for ProMeter on the App Store. • Android: Contact customer service or visit the official website: http://prometer.cn. Installation Instructions: 1. Unscrew the back cover, insert the 16340 chargeable 3.7v lithium battery ensuring correct polarity (spring side connects to the negative terminal), then screw the back cover on tightly. 2. Check if the threaded port has an O-ring seal and if the seal is intact. If the seal is damaged or incomplete, replace it immediately. 3. Wrap the threaded port with an appropriate amount of PTFE tape (high-temperature resistant PTFE tape is recommended) to ensure adequate sealing so the screen can be properly oriented for display. 4. Using Flair 58 as an example, unscrew and remove the original pressure gauge, then screw in this product, tightening it adequately to ensure no water leakage during extraction operations. FCC Warnning: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection againstharmful interference in a residential installation.
