Digital electronic clock, microcontroller electronic form, (time + temperature + voltage) triple spreadsheet

product features:
1: super small volume, installation dimensions: length = 40.2 mm width = 12.8 mm thick material. 14 mm
2: time, temperature, voltage three functions in one. Three kinds of functions can switch at any time.
3: a total of 4 kinds of display mode. (1) (2) show only the temperature (3) show only the time only display voltage alternating voltage (4) the time temperature display.
4: with manual temperature error correction function, set the range – 5 ~ 5 ?.
5: with a backup battery, power lost time went on.
Electrical properties:
1:5 ~ 15 v input voltage. Note that to use the voltmeter function, at least more than 7 v input voltage
2: voltmeter 7 ~ 15 V range, error of plus or minus 0.1 V, voltage measurement is the input voltage
3: the temperature range – 9 ? ~ 60 ?
Method of use:
1, adjust the time and temperature error correction
The normal service condition, press the “left” and “points” start flashing, at this time, in accordance with the “right”, “points” to increase, and circulation between 59 ~ 0. Adjusted the “points”, and then press “left”, “” began to flicker, at this time, in accordance with the” right “, “when”, and between 23 ~ 0 circulation. Adjusted the “when”, then press “left”, the display AC: xx, xx temperature value is to be revised, the unit is degree. Revised in accordance with the “right” to adjust temperature error, range from – 5 ? ~ 5 ?, positive number is increased, negative number is decreased. After adjusted the temperature error correction, and then press “left”, save all the data, and return to normal display status.

2, switch the display mode
In the condition of the adjustment, press the “right” to switch display modes, from (1) only show the time – (2) show only the temperature – (3) – (4) show only the voltage switching between voltage alternating time temperature. And save the final model, even if the power switch on again.
