RX8025T DS1302 LED Electronic Clock High-Precision Clock Module On-Board Clock Temperature Luminous VehicleItem NO.: DS13RX80

RX8025T DS1302 LED Clock Module

Product Introduction:

The new three-in-one electronic clock module integrates three practical functions: time, thermometer and voltmeter. The DS1302/RX8025T clock chip with temperature compensation crystal oscillator is used. Its timing accuracy and stability, as well as the extended temperature probe, effectively solve the problem of inaccurate temperature affected by the module temperature. Ultra-wide power supply voltage, supporting 6~30V DC.

Product Parameters:

1. Power supply voltage: DC6.0~23V

2. Temperature function range: - 40~120 degrees, resolution 0.1 degrees.

3. Functional range of voltmeter: DC5~23V (pure DC power supply is required)

4. Module size: 4cmx1.3cm super small

Functions And Instructions:

Adjust the time, date, year, voltage error, temperature error cycle display item definition, and alternate display interval time

In the non-set state, press the left key to enter the time adjustment (note that the colon in the middle is on),

1. At this time, "Minute" starts to flash, press the right button to increase, and the adjustment range is 00~59. After adjusting "Minute",

2. Press the left key again, and the "hour" starts to flash. Press the right key to increase, and the adjustment range is 00~23.

3. After the "hour" is adjusted, press the left key to enter the date adjustment (note that the colon in the middle is off). At this time, the "day" starts to flash, and press the right key to increase the adjustment range 1-31.

4. After setting the "day", press the left button again, and then the "month" will start flashing. Press the right button to increase the adjustment range 1-12.

5. After the date is adjusted, press the left key again. At this time, the "year" starts to flash. Press the right key to increase the adjustment range 2012-2049.

6. After adjusting the "year", press the left key again to enter the error calibration function of display voltage [x.xU]. The unit is 0.1V. A positive number indicates an increase and a negative number indicates a decrease.

7. Then press the left key again to enter the temperature error calibration setting [Ac: xx], where xx represents the correction value, and press the right key to increase. A positive number represents an increase, and a negative number represents a decrease, in degrees.

8. Press the left key again to enter the definition function dd option of the display item under the cycle display status. Press the right key to change the value: (dd: 0) time+temperature+voltage, (dd: 1) time+voltage, (dd: 2) time+temperature, (dd: 3) temperature+voltage. Then press the left key to enter the cycle display alternate interval dF option. Press the right key to change the value. The larger the value, the longer the interval. DF Do not set 0, otherwise the screen will be black.

9. Then press the left key to save all the set values and return to the normal display status.

Option Parameters:

1. [Ac: xx]: xx represents the correction value, press the up key to increase, positive number means increase, negative number means decrease, unit: degree

2. dd options: (dd: 0) time+temperature+voltage, (dd: 1) time+voltage, (dd: 2) time+temperature, (dd: 3) temperature+voltage.

3. dF option: cycle to display the alternate interval dF option. Press the up key to change the value. The larger the value, the longer the interval. Do not set DF to 0, otherwise it will turn to black screen. Then press the key again to enter the brightness level setting LL: 1, and press the up key to change the value, a total of 3 levels.

4. AL option: Automatic control setting AL: 0, press the up key to change the value, 1 is valid, 0 is invalid. The meaning of automatic brightness control is that the brightness will automatically change to level 1 from 19:00 to 6am. Then press the key again to save all the set values and return to the normal display state.

5. LL option: Nixie tube brightness adjustment, the greater the value, the higher the brightness

Toggle Display Items:

In the non-set state, press the right button to switch the display items, and the display will switch between time -->date -->temperature -->voltage -->alternating cycle display. (Note: the date does not participate in the cycle) Switch the display in turn. Press the right button in the non-adjustment state to wait for a few seconds and observe whether the rotation is displayed. If not, press the right button to wait for a few seconds until the rotation is displayed.

Be Careful:

1. About the inaccurate timing, the timing does not go. It needs to be set and switched out before it starts to go from the set time. So if you set the score according to the current time, you will definitely feel slow. When you adjust the timing, please pay attention to it.

2. About the problem of temperature inaccuracy, there are some reports of temperature inaccuracy. In fact, the difference between the measured temperature and the actual temperature is not large. The temperature can be compared by tying two probes together with the temperature point you are comparing, rather than placing them in different places.

3. The digital tube is an active light emitting device. It may not be very clear under direct sunlight or strong light. The effect of dark light or night is very good. At the same time, the brightness of blue is higher than other colors. You can try to choose blue.
