12V 24V Car Auto Digital Led Electronic Time Clock + Thermometer + Voltmeter Three Colors

Description:

Length: 40.2mm, width = 12.8mm, thick ≈7mm
Display color: red, yellow, blue
Display mode:

1.display time only
2.temperature display only
3.display only voltage
4. time temperature voltage alternating display (Note: alternate display mode, by dd option to choose whether to display the temperature or voltage, dd: 0 Status display time + temperature + voltage .dd: displaying a state time + voltage .dd : Displays the status of time + temperature 2)

Note: Please inform us which display color you would like after you make an order, or we will ship the items to you by random, thank you!

Features:
1. Set the time, temperature, voltage, three functions in one
2. manual error correction function with a temperature setting range -5 ~ 5
3. With backup battery, power-down time to continue to go
Electrical Characteristics:
1. Input voltage 5 ~ 30V. Note that to use a voltmeter function, the input voltage is at least more than 7V
2. voltmeter range 7 ~ 30V, error ± 0.1V, the measured voltage is the input voltage.(Can also function as a wide range of uses voltmeter, power is more convenient,such as a pen so you can remember this power, and do not exceed the maximumvoltage of 30V)
3. Temperature measurement range -50 to 130 degrees, the temperature resolution of up to 0.1 degrees
4. Working current of about 30MA

How to use:
1, adjust the time and temperature error correction
Under normal use, press the “left”, “minute” starts flashing, then press the “Right”, “minute” increase, and between 59 to 0 cycles. Good tune “minute” and then “left”, “when” starts flashing, then press the “Right”, “when” the increase, and between 23 to 0 cycles. Tuned “when”, the followed by “left” is displayed AC: xx, xx is the valueto be corrected temperature value in degrees. Press the “Right” to adjust thetemperature error correction value, ranging from -5 ~ 5 , a positive number isincreased, the negative is reduced. After a good tune temperature error correction,and then “left” to save all the data, and return to normal display.
(Note: After long working hours, such as high temperature measured, it is becausethe regulator circuit board on the heat, and the board is relatively small, the heattransfer to the temperature resistance, so that the measured temperature is high,the solution is to pick out the temperature resistance with some lines, it left theboard can be solved)
2, switch the display mode
In the non-adjustment of status, press the “right” to switch the display mode,displaying only the time from 1 →2 → 3temperature display only shows the voltage→ 4only time temperature display switches between voltage alternating cycles. And save the final model, even power off.
