1, the temperature OOTDTY The temperature display range is -99°-999°. Unit C is Celsius and F is Fahrenheit. Temperature unit It can be switched by pressing the "+" key. 2, the use of time / flow rate display When there is water flow, it will automatically jump to the flow rate display, and when there is no water flow, the total time will be displayed. Total time unit Indicates , HRS indicates hours, and time units can be switched by long pressing the "+" key. temperature display Use time/flow rate display Water flow painting display Total flow character character TOTAL Battery indication Total water consumption The flow rate unit LPM is “l/min”, GPM is “gallon/min”, can be short-pressed by “-” Key switch. 3, battery prompt The battery alert icon flashes when the battery is low, prompting the user to replace the battery. In electricity It will not be displayed if there are sufficient quantities. 4, water flow painting When a flow of water is detected, the stream head animation will begin to show the water droplets. 5, total water consumption, flow rate display The 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 10000L (or GAL) will be accurate to two decimal places, when the total water consumption is greater than 9999.99 L (or GAL) The decimal point will be hidden. The maximum measurement 999999L (Note: If the upgrade, if the unit is set Into the GAL, also count 999999L clear 0, that is, remember to 219969GAL clear 0), after more than Remeasurement starts at 0. 6, 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 7, Total Traffic Character (TOTAL) When the system is powered on, the total flow character is displayed on the main screen. , three, settings and interface description 1, how to set the system operating mode Use the battery three AAA battery interface to power the system.& 65288;Not include battery& 65289; 2, the main interface and the main interface settings The characters TOTAL, total water consumption, temperature, total usage time, etc. will be displayed under the main screen. 3. Setting of K value setting interface and K value setting interface In the main interface, short press “SET” key once to jump to the K value setting interface. “K SETTING”, interface number 00, and K value are displayed under the K value setting screen. Press the “SET” key in the K value setting interface to set the K value. The first digit of the K value after long pressing the "SET" key Flashes, short press “+” flashes digits increases by 1; short press “-” flashes digits decreases by 1; short press “SET” Press to switch to the next digit. After setting, long press “SET” key to save the settings.
