I, product Features:

1. Temperature detection inside and outside the car. The temperature measurement enclosure is-50-70 degrees.

2. When the temperature is lower than-1 degree, the icing alarm pattern lights up.

3. Real-time monitoring of battery voltage in the car, digital display of current voltage.

4. The time display function displays the year, month, and day on Button.

5.12 and 24-hour display system.

6. Blue and orange backlight color conversion.

1. Plug the vehicle-mounted cigarette lighter plug into the vehicle-mounted cigarette lighter, and place the outdoor probe on the inside of the outer door of the vehicle to fix it, so as to start the vehicle, the display screen displays the current temperature inside and outside the car and the battery voltage and time inside the car.

2. When the temperature outside the car is from-1 to 4 degrees, the ICE display pattern will be displayed, indicating that the temperature outside the car is low, and pay attention to the anti-freezing maintenance of the car.

4. The number on the right shows the voltage of the battery in the car in real time. A. If the battery voltage in the car is below 9V, there is A pattern on the right display screen at this time: at this time, the battery voltage is very low and the vehicle is in danger of flameout, so the vehicle needs to be tested immediately. B. If the battery voltage in the car is between 9.1V and 11.5V, the display screen on the right has a pattern: at this time, the battery voltage is low, and the vehicle needs to be tested. C. If the battery voltage in the car is 11.6 ------ 11.9V, the display screen on the right has a pattern: at this time, the battery voltage can be driven, but the voltage is still low. D. If the battery voltage in the car is 12V to 12.4V, the right side of the product VOL. At this time, the display screen on the right has a pattern: at this time, the battery voltage can be driven. E. If the battery voltage in the car is from 12.5V to 12.9V, the right side of the product VOL shows the pattern on the right display screen at this time:

at this point, the battery voltage of the car is normal. F. If the battery voltage in the car is 13V to 15V, at this time, the display screen pattern on the right is: at this time, the battery voltage is too high. When the voltage reaches above 14.8V, the vehicle needs to be detected immediately.

5. Push the switch on the side to switch between blue and orange backlight colors.

6. If it is used or the display is abnormal due to some other factors, take out the battery for a while and reinstall the battery. You can also press the "RESET" button on a sharp object to reuse it.

3. Time setting

2. Press the TIME key at this TIME to set the following items: 12/24 hours --- seconds --- hours-minutes-years --- months --- date --- confirm exit.

3. Press the UP or DOWN key to raise or lower the Project respectively.

4. In the general TIME state, press the TIME key once to switch to the display state of month and date.

5. Press the °C/F key to convert degrees Celsius and degrees Fahrenheit.
