Ⅰ. Food temperature measurement range: -20 - 105. Body temperature resistance: above 300. Ⅱ. The product uses 5.1BLE power Bluetooth master control, which is compatible with BLE4.2. The transmission distance is 30 meters to 50 meters without a screen, more than 10 meters within a 10-meter holding space. After more than 10 meters of a delimited metal wall, the transmission distance is the ambient temperature is not more than 20%. Ⅲ. The mobile phone can monitor the cooking process for six probes at the same time. Multiple working modes: recipe / target temperature / estimated cooking time. Ⅳ. Stainless steel structure. USB charging, because the metal structure cannot be put into the microwave. 20 minutes of quick charging can work for more than six hours, and it takes about 20 minutes to fully charge. The green light on the base lights up after full charging. Ⅴ. Material: bamboo base, stainless steel probe. Product size: 17.3 * 3.2 * Probe. Ⅵ. Some probes that have not been charged for a long time will not turn off the red light after 20 minutes of charging. At this time, it takes about six hours to reach at least 95%. The remaining 5% of the battery will be charged with a very low current to protect the battery, which may take a long time. Therefore, it does not need to be charged for 2 minutes, if it does not need 2 minutes, then 2 minutes again. It does not need to be charged to 100%. The difference in working hours is not significant. Full 100%, the longest working time is about 8 hours. 95% working time can be more than 6 hours. Ⅶ. Remove the probe from the charging socket and insert it into the food. The insertion depth should be as far as possible beyond the safety line; Each grill skewer is independent of each other, and the grill mode can be set for each probe separately; The cooking setting system in the recipe setting functions menu has also set 9 cooking types and cooking level values. also set the temperature in the recipe itself.
