2.Using the EPSON RX8025T or DS3231 comes TCXO clock chip, with ultra-high timing accuracy and stability,
extended temperature probe, effective solution to a temperature module
3.Temperature insufficient registration problems.
4.Wide supply voltage, supports 5 ~ 30V DC.

Product parameters
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)
4.Size: 40x13mm
5.Color:Red,Green,Blue

How to use
Under non-setting state, press the left button of adjustment time (note in the middle of the colon is bright),

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.

How to change
Second, 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
switched between the circular display.

NOTE
1.When used, the temperature of the probe as far away from the board,or the clock will heat affect the temperature measurement.
2..Please allow 1-2mm error due to manual measurement. Please make sure you do not mind before you bid.
3.The colors may have different as the difference display, please understand.

Package include:
1 x Digital Car Clock Time+Temperature+Voltage 3in1 Meter
