DS3231SN 3 in 1 LED
Under non-setting state, press the left button of adjustment time (note in the middle of the colon is bright),
1. At this time "minute" starts flashing, increase press right, adjust the range 00 to 59. After a good tune, "minute",
2. Press the left button, then the "hour" starts flashing, increase press right, adjust the range 00 to 23.
3. tuned "hour", then press the left into the adjustment date (note in the middle of the colon is off), then "day" starts flashing, press right to increase adjustment range 1-31.
4. tuned "day", then press the left button, then the "month" starts flashing, press right to increase adjustment range 1-12.
5. After adjusting the date, then the left, then "year" starts flashing, increase press right, adjust the range 2012-2049.
6. adjust the "year", then press the left button, go to show the error voltage calibration function [x.xU], the unit is 0.1V, a positive number indicates an increase, a negative number indicates decrease.
7. Then press the left button, enter the temperature error calibration settings [Ac: xx], xx on behalf of the correction value, increased by right, a positive number indicates an increase, a negative number indicates decrease in degrees.
8. Press the left, into the cycle defined function dd option status display items, press the right to change the value: (dd: 0) time + temperature + voltage, (dd: 1) time + voltage, (dd: 2 ) time + temperature, (dd: 3) Temperature + voltage. Press the left button, the display alternately into circulation interval dF option, press right to change the value, the greater the value the longer the interval. DF Do not set to 0, otherwise it will be black.
9. Finally press the left button to save all settings value and return to normal display.
How to change
Secondly, switch the display items
Under non-setting state, press the right key to switch the display,
the display will be in time ---> Date ---> Temperature ---> voltage ---> alternately
