When a flow of water is detected, the head animation will begin to show the water droplets. water consumption, flow rate display.The water consumption is expressed in litres of L and gallons of gallons, and the unit is passed. When the water consumption is less than 10000L (or GAL) will be accurate to two decimal , when the water consumption is 9999.99 L (or GAL)The decimal point will be . The maximum measurement 999999L (Note: If the upgrade, if the unit is set.Into the GAL, also count 999999L clear 0, that is, to 219969GAL clear 0), after more than.Remeasurement starts at 0.K value setting character (K SETTING)The K value setting character will be displayed when entering the interface number: 00 for the K value setting interface (K SETING)Show it Character ().When the system is powered on, the flow character is displayed on the main screen.three, and interface description: PlumbingMeasurement Range: 999999Lthe temperatureThe temperature display range is -99-999 Celsius. Unit C is Celsius and F is Fahrenheit. Temperature unitIt can be switched by pressing the "+" key.the use of time / flow rate displayWhen there is water flow, it will automatically jump to the flow rate display, and when there is no water flow, the time will be displayed. time unit DAYIndicates , indicates hours, and time units can be switched by long pressing the "+" key.temperature displayUse time/flow rate displayWater flow painting display flow character character Battery indication water consumptionThe flow rate unit LPM is "l/min", GPM is "gallon/min", can be short-pressed by "-"Key switch.battery promptThe battery alert flashes when the battery is low, prompting the to replace the battery.
