1, The temperature of the temperature display range is -99°-999°. Unit C is Celsius and F is Fahrenheit. Temperature UnitIt can be switched by pressing the "+" button.2, 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 total time will be displayed. Total time unit dayIt indicates days, hours indicate hours, and time units can be switched by long pressing the "+" key. Temperature DisplayUse Time/Flow Rate DisplayWater Flow Painting DisplayTotal Character Flow Total Battery Level IndicatorTotal Water ConsumptionLPM Flow Rate Unit is "L/min", GPM is "Gallon/min", can be briefly pressed by the "-" key switch.3, battery statusThe battery alarm icon flashes when the battery is low, prompting the user to use the battery. ElectricityIt will not be displayed if there are sufficient quantities.4, water flow paintingWhen water flow is detected, the animation of the jet head will start to show water droplets.5, total water consumption, flow rate indicatorThe total water consumption is expressed in L liters and gallons gallons, and the unit is transmitted. 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 the 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, the K value setting mark (K setting) will be displayed when entering the interface number: 00 for the K value setting interface (K setting)Show that7, total movement sign (total)When the system is powered on, the total flow sign is displayed on the home screen., Three, settings and interface description1, how to set the system working modeUse the battery three AAA battery interface to power the system. (not include batteries)2, main interface and main interface settingsTotal characters, total water consumption, temperature, total use time, etc. will be displayed under the main screen.3. Setting the K-value setting interface and the KW value setting interface of the main interface, short press the "SET" key 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, other1, system sleep mechanismUsing battery interface power supply, in order to save power and improve battery life, the system is unmannedAnd if there is no water flow, it will go to sleep. The display will automatically jump to sleep on the main interface and keep the display function. It automatically wakes up to the measurement state when water flows through.2, system resetThere is a reset symbol on the back of the hob with two contacts next to it. Two contacts when the system is turned onShort circuit to about 2 seconds, the system will restore the factory settings, clear the total time and total water consumption. Flow Sensor G1/2: Water Pressure Resistance 1.75mpaFlow Range 1-25L/minWith Temperature SensorThis flow meter can only use this flow sensor, because this flow sensor is a customized version with low power consumption, if use other flow sensor not low power consumption, the battery can only use two days (not include 3 * AAA battery)
