Car Led Clock, Electric Clock Digital Timer Temperature Clock with Green/Blue/Red Light Car Decorative Accessories (White)

Features: Instructions: Adjust time and temperature error correction In normal use, press the "Left Button" and the "Min" will start to flash. At this time, press the "Right Button" and the "Min" will increase and cycle between 59-0. Adjust the "minute" and press the "left button" again, and the "hour" starts to flash. At this time, press the "right button" to increase the "hour" and cycle between 23 and 0. After adjusting the "hour", then press the "left button" again, and AC: is displayed at this time. The value of is the temperature value to be corrected, and the unit is degree. Press the "right button" to adjust the temperature error correction value, the range is from -5°C to 5°C, a positive number increases, and a negative number decreases. After adjusting the temperature error correction, press the "left button" again to save all the data and return to the normal display state. (Note: Some netizens reported that after working for a long time, the measured temperature was too high. That is because the voltage regulator circuit on the board heats up, and the board is relatively small. The heat is transferred to the temperature measuring resistor, so that the measured temperature is too high. High, the solution is to connect the temperature measuring resistor with a piece of wire and let it leave the board.) Specification: Type: Car clock Material:Plastic Color:Black Light Color: Blue/red/green Quantity:1pc Input voltage: 5 ~ 20V (to use the voltmeter function, the input voltage is at least 7V or more) Voltmeter range: 7 ~ 20V, error ?± 0.1V Temperature measurement: -50 to 130 degrees Working current: 30MA Item Size:4*1.3*1.4cm/1.6*0.5*0.6"(L*W*H) Cable Length:20cm/7.86" Net Weight: 7.5g/0.27oz Package: 1*Car clock

• [Installation Method]---Just connect the positive and negative poles of the clock with the positive and negative poles of the power supply. Generally, red is the positive pole and black is the negative pole. If you can't connect or the link is wrong, please don't worry, feel free to contact us, we will answer for you.
• [Easy to Read]--- The digital clock uses large led numbers to tell time at a glance. The digital display is easier to read and easier to use.But at the same time, it has -small size, portable and easy
• [4 Modes] ---There are 4 display modes in total. 1:Display time only; 2: Display temperature only ;3: Display voltage only ;4 :Time temperature voltage alternately displayed (Note: In the alternate display mode, the dd option can be used to select whether to display temperature or voltage, dd: 0 state display time temperature voltage;Dd: 1 shows the time ;voltage. dd: 2 shows the time temperature)
• [Thermometer Function]---This mini led clock displays hours and minutes. It allows you to know the time when driving without glancing at your watch or cell phone, which ensures a safer driving experience.: Temperature measurement range is -50 to 130 degrees. With manual correction of temperature error, the setting range is -5~5°C
• [Universal Product]--- This mini clock fits for any car, truck, etc,also suitable for home, office etc, it combine time, temperature and voltage. Three functions can be switched at any time
