1, The temperature temperature display range is -99°-999°, the unit C indicates the temperature, F indicates the Fahrenheit temperature. The temperature unit can be changed by pressing the + key. 2, the use of time/flow rate display in the flow meter mode will automatically jump to the flow rate display, no flow time display total time (water pressure mode only show time). DAY indicates the day and HRS indicates the hour. The time unit can be changed by holding down the + key. Flow rate unit LPM indicates liters per minute, and GPM indicates gallons per minute. You can press. Number key switch. The current screen number is displayed on another screen. 00 indicates the KSETING screen. 3, power indicator The power indicator will be displayed and blink when the battery is low, prompting the user to replace the battery. It won't show on a full charge. 4, faucet animation (only flow meter mode) When water is detected, the faucet animation will start to show water droplets. 5, total water consumption, flow rate display total water consumption with the unit L represents liters, GAL represents gallons, the unit can be passed. When the total water consumption is less than 10,000 L(or GAL), it is accurate to two decimal places, and when the total water consumption is greater than 9999.99L(or GAL), the decimal point value is hidden. The maximum measurement is 999999L (note: in liters, if the unit is set to GAL, it is also clear 0 when the count is full 999999L, that is, clear 0 after recording 219969GAL), and re-measure from 0 after exceeding.
