1, Temperature Temperature Display Range is-99°-999°. Unit C is Celsius and F is Fahrenheit. Temperature unit It can be switched by pressing the "+" button. 2, The use of time/flow rate display When there is water flow, it will automatically jump to flow rate display, and when there is no water flow, the total time will be displayed. Total time unit day Indicates days, hours indicate hours, and time units can be switched by long pressing the "+" key. Temperature Display Use Time/Flow Rate Display Water Flow Painting Display Total Character Character Flow Total Battery Level Indicator Total Water Consumption LPM Flow Rate Unit is "L/min", GPM is "Gallon/min", can be briefly pressed by "-" Key switch. 3, Battery Status The battery alarm icon flashes when the battery is low, prompting the user to use the battery. Electricity will not be displayed if there are sufficient quantities. 4, Water flow painting When water flow is detected, the animation of the water head will start to show water droplets. 5, Total water consumption, flow rate rate The total water consumption is expressed in L liters and gallons gallons, and the unit is conveyed. When the total water consumption is less than 10000L (or GAL) it will be accurate to two decimal places, when the total water consumption is more than 9999.99 L (or GAL) the decimal point will be hidden. Maximum measurement 999999L (note: if update, if the device is set to GAL, also count 999999L clear 0, that is, remember 219969GAL clear 0), after more than Remeasurement starts from 0. 6, K value setting mark (K setting) The K value setting character will be displayed when entering the interface number: 00 for the K value setting interface (K setting) Show that 7, the total movement mark (total) When the system is on, the total flow mark is displayed on the home screen. , Three, settings and interface description 1, how to set the system working mode Use the battery three AAA battery interface to power the system. (not include batteries) 2, the main interface and the main interface settings Total characters, total water consumption, temperature, total use time, etc. will be displayed below the main screen. 3. Setting the K-value setting interface and the K-value setting interface In the main interface, short press the "SET" button to enter the K-value setting interface. "K" setting, interface number 00 and K-value are displayed under the K-value setting screen. Press the "SET" button 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 increase by 1; Short press "-" flashes digits decrease by 1; Short press "SET" Press to skip to the next digit. Once set, press and hold the "SET" button to save the settings. Four, the other 1, the system sleep mechanism Using the power supply of the battery interface, in order to save energy and improve battery life, the system is unmanned And if there is no water flow, it will go to sleep. The display will automatically jump to sleep status Main interface and keep the display function. It automatically wakes up to the measurement state when water flows through. 2, system reset On the back of the board there is a reset symbol with two pins next to it. Two contacts when the system is turned on Short circuit to about 2 seconds, the system will restore factory settings, clear the total time and total water consumption. G1/2 Flow Sensor: Water Pressure Resistancegt; 1.75mpa Flow Range 1-25L/min With Temperature Sensor This flow meter can only use this flow sensor, because this flow sensor is a customized version with low power consumption, if use otherflow sensor not low power consumption, the battery can only use two days (not include 3 * AAA battery)
