Introduction:
The latest three-in-one electronic clock module, set time, thermometer, voltmeter three practical functions in one, using the built-in temperature compensation crystal DS3231 clock chip / Epson RX8025T clock chip, with ultra-high timing accuracy and stability , Extended the temperature probe, an effective solution to the problem that the temperature of the module temperature is not enough. Ultra wide supply voltage, support 5 ~ 30V DC.
Product parameters:
1, the supply voltage: DC5.0 ~ 30V
2, the temperature function range: -40 ~ 120 degrees, resolution 0.1 degrees.
3, the voltmeter function range: DC5 ~ 30V (need pure DC power supply, not recommended 24V battery use, because the voltage may be charged too high, burned)
4, the module size: 40x13mm ultra-small
Delivery does not provide paper instructions, please refer to the page settings, thank you
Function and instructions:
First, adjust the time, date, year, voltage error, temperature error cycle display item definition, alternate display interval
In the non-set state, press the left button, enter the time adjustment (note the middle of the colon is bright),
1. At this time, "minutes" start flashing, press the right button to increase, adjust the range 00 ~ 59. After adjusting the "points"
2. Press the left button again, then "hour" starts flashing, press the right button to increase, adjust the range of 00 ~ 23.
3. Adjust the "hour", then press the left button to enter the date of adjustment (note the middle of the colon is off), then "day" began to flash, press the right to increase, adjust the range 1-31.
4. Adjust the "day", then press the left button, then "month" began to flash, press the right button to increase, adjust the range 1-12.
5. Adjust the date, then press the left button, then "Year" began to flash, press the right to increase, adjust the range 2012-2049.
6. After adjusting the "Year", press the left button again, enter the error calibration function [x.xU] of the display voltage, the unit is 0.1V, the positive number increases, and the negative number decreases.
7. Press the left button again to enter the temperature error calibration setting [Ac: xx], xx for the correction value, press the right button to increase, the positive sign increases, the negative number decreases, in degrees.
(Dd: 1) time + voltage, (dd: 2), and then press the left button to enter the loop display state. ) Time + temperature, (dd: 3) temperature + voltage. And then press the left button to enter the cycle to display the alternate interval dF option, press the right button to change the value, the greater the value the longer interval.
9. Finally, press the left button to save all the set values and return to the normal display state.
After the upgrade, the clock error is normal within 10 seconds per month
Second, switch display items
In the non-set state, press the right button to switch the display item, the display will be in the time ---> date ---> temperature ---> voltage ---> alternating cycle display between the switch.
NOTE :
When used, the temperature of the probe as far away from the board,or the clock will heat affect the temperature measurement
