["1, the temperature\nThe temperature display range is -99°-999°. Unit C is Celsius and F is Fahrenheit. Temperature unit\nIt can be switched by pressing the \"+\" for key.\n2, the use of for time / flow rate display\nWhen there is water flow, it will automatically jump to the flow rate display, and when there is no water flow, the total for time will be displayed. Total for time unit DAY\nIndicates days, HRS indicates hours, and for time units can be switched by long pressing the \"+\" for key.\ntemperature display\nUse for time/flow rate display\nWater flow painting display\nTotal flow character character TOTAL\nBattery indication\nTotal water consumption\nThe flow rate unit LPM is “l/min”, GPM is “gallon/min”, can be short-pressed by “-”\nfor Key switch.\n3, battery prompt\nThe battery alert icon flashes when the battery is low, prompting the user to replace the battery. In electricity\nIt will not be displayed if there are sufficient quantities.\n4, water flow painting\nWhen a flow of water is detected, the stream for head animation will begin to show the water droplets.\n5, total water consumption, flow rate display\nThe total water consumption is expressed in litres of L and gallons of gallons, and the unit is passed. When the total water consumption is less than\n10000L (or GAL) will be accurate to two decimal places, when the total water consumption is greater than 9999.99 L (or GAL)\nThe decimal point will be hidden. The maximum measurement 999999L (Note: If the upgrade, if the unit is set\nInto the GAL, also count 999999L clear 0, that is, remember to 219969GAL clear 0), after more than\nRemeasurement starts at 0.\n6, K value setting character (K ​​SETTING)\nThe K value setting character will be displayed when entering the interface number: 00 for the K value setting interface (K SETING)\nShow it\n7, Total Traffic Character (TOTAL)\nWhen the system is powered on, the total flow character is displayed on the main screen.\n, three, settings and interface description\n1, how to set the system operating mode\nUse the battery three AAA battery interface to power the system.（Not include battery）\n2, the main interface and the main interface settings\nThe characters TOTAL, total water consumption, temperature, total usage for time, etc. will be displayed under the main screen.\n3. Setting of K value setting interface and K value setting interface\nIn the main interface, short press “SET” for key once to jump to the K value setting interface.\n“K SETTING”, interface number 00, and K value are displayed under the K value setting screen.\nPress the “SET” for key in the K value setting interface to set the K value. The first digit of the K value after long pressing the \"SET\" for key\nFlashes, short press “+” flashes digits increases by 1; short press “-” flashes digits decreases by 1; short press “SET”\nPress to switch to the next digit. After setting, long press “SET” for key to save the settings.\nFour, other\n1, the system's sleep mechanism\nIn the use of battery interface power supply, in order to save energy and improve battery life, the system is unmanned\nAnd if there is no water flow, it will go to sleep. The display will automatically jump to the sleep state\nThe main interface and keep the display function. Automatically wakes up to the metering state when water flows through.\n2, the system reset\nThere is a RESET symbol on the back of the board with two contacts next to it. Two contacts after the system is powered on\nShort-circuit to about 2 seconds, the system will restore the factory settings, clear the total for time and total water consumption.\n\nG1/2 flow sensor :\nWater pressure resistance> 1.75MPa\nFlow range 1-25L / min\nWith Temperature Sensor\nThis Flow Meter Only can use this Flow Sensor , Because this Flow sensor is Customized version Low power consumption ,If use other Flow Sensor not Low power consumption, the battery only can use two days（Does not include battery Use 3*AAA battery）"]
