Car Three-in-one Time Temperature Voltage Multi-function LED Dot Matrix Clock Home Modification DIY 4.0 ~ 25V RX8025T Precision

product description: 1. Multi-functional ultra-thin electronic clock module, thickness of only 10mm, set time, temperature, voltage as one. 2. It is possible to display a single item individually, or to display the items alternately in cycles, and to customize the items to be displayed. 3. Time chip uses Epson's RX8025T chip, this chip is a clock chip with temperature compensation, accurate time. 4. Temperature display range -35~120 degrees. 5. With brightness adjustment function, 5 brightness adjustable. 6. With automatic brightness function, it can achieve darkening at night and brighten during the day. Parameters and Dimensions: 1, the working voltage: DC 4.0 ~ 25V 2、Dimensions: 93*36*10mm[Long thick] 4, voltage display range: 4.0 ~ 25V 5, temperature display range: -35 ~ 120 °C dog In the normal display state, short-pressing the setting key will switch between the five display of [time]→[date]→[temperature]→[voltage]→[alternate cycle display]. Press In the normal display state, press and hold the setup button for more than 2 seconds to enter the setting of time\date\year\parameter. "Minute" starts flashing, short press the setting key to adjust the value. After adjusting, press and hold the setting button for more than 2 seconds. "Time" starts flashing. Short press the setting button to adjust the value. Then long press the setup button for more than 2 seconds to enter the date adjustment [note that the middle colon is not lit at this time]. The “day” starts flashing. After adjusting, press and hold the setup button for more than 2 seconds to start flashing. Long press the setup button for more than 2 seconds to start flashing. After tuning, press and hold the setup button for more than 2 seconds to enter the extended parameter setting. For details, see the following table “Code Meaning and Function”. After entering the code function setting, it is also possible to press the setup button for more than 2 seconds to skip to the next parameter setting. Short-press the setup button to adjust the parameter value. Refer to the following table for the meaning of the code: Ac: Temperature 1 error calibration parameter. A positive number represents an increase, a negative number represents a decrease, and the unit is degree. The adjustment range is -5~5. For example, if you think that the displayed temperature is 1 degree higher than the actual temperature, then set Ac:-1 so that the electronic clock is automatically displayed after subtracting 1 degree. (Note: If you do not have a standard thermometer for reference, it is recommended to keep this item as Ac: 0)   Dd: Display item during custom cycle display [dd: 0] Time + temperature + voltage [dd: 1] Time + voltage [dd: 2] Time + temperature   dF: Switching interval when the custom cycle is displayed, the unit is second, the adjustment range is 1~9. For example dF: 3, just The switching interval is about 3 seconds to switch display items.   LL: Displays the brightness level, the adjustment range is 1~5, LL: 1 is the darkest, and LL:5 is the brightest.   AL: Automatic brightness control switch, AL:0 is the automatic brightness control, AL:1 is the automatic brightness control. When set to AL:1, the electronic clock will change the brightness to level 1 after 19:00 PM every day. After 7:00 AM every day, the brightness will be changed to the luminance levelLL option.   0.0u: The voltage measurement error is corrected. A positive number indicates an increase, and a negative number indicates a decrease. For example, the actual supply voltage is 12.0V, but the table shows 11.9V, then it is adjusted to 0.1u. After adjusting the AL option, press the SET button for more than 2 seconds at the end. After returning to the normal display state, all parameters and time settings can be saved.
