er three kinds of practical functions in one,
using the DS3231 comes TCXO clock chip, with ultra-high timing accuracy and stability,
extended temperature probe, effective solution to a temperature module
temperature insufficient registration problems.
Wide supply voltage, supports 5 ~ 30V DC.
1, power supply voltage: DC5.0 ~ 30V
2, the temperature function range: -40 to 120 degrees, resolution 0.1 degrees.
3, voltmeter function Range:DC5 ~ 30V(need pure DC power supply,
24V battery is not recommended for use because of possible charging voltage is too high, burning)
How to use
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 statu
