White Inverted 12-24V Moon Type Car LED Thermometer Voltmeter Clock LED Display Car Dashboard Clock Dual Temperature Sensor

1. Working voltage:DC 8-30V
2. It can measure and display the temperature inside and outside of car.
3. Temperature display range:-40 ~ 120 Centigrade
4. With temperature error correction setting function.Setting range -5~5 Centigrade
5. Measure temperature range:6 ~ 28V.
6. With voltage error correction setting function.Setting range -0.5V ~ 0.5V
7. 6kinds display mode:
1>. Display date only;
2>. Display time only;
3>. RT0 display temperture only;


   4>. RT1 display temperture onley;  
5>. Display voltage only;
6>. Displayed alternately above;
NOTE:ON displayed alternately mode,user can select display by "dd" option.
1>. dd:0   display:time+RT0+RT1+voltage
2>. dd:1   display:time+RT0+RT1
3>. dd:2   display:time+RT0+voltage
4>. dd:3   display:time+voltage
8. Digital tube brightness correction settings(LL:xx).The larger the number, the brighter the LED.
9. Automatic brightness control settings(AL:0):"1" Valid, "0" invalid.This function means:Brightness will automatically become "1" at 19:00 to 6:00
10. Set display the time interval at Displayed alternately.
11. temperature probe : 0.3meter and 1.5meter, the single verison only have 1.5meter proble

Keyboard plate has two touch keys: L (left), R (right);
1. Under normal use, touch the "L", "minute" starts flashing, then press the "R", "minute" increases between 00 to 59 cycles. After setting "minute" and then press the "L", "hour" starts flashing, it increases between 00 to 23 cycles. After setting "hour" and press "L" to adjust the date, then "date" starts flashing, press UP to increase between 1 to 31 cycles, then is month  , and year , the same as hours.
2. Then press "L" , displayed 0.0V, this is voltmeter error adjustment, from -0.5-0.5V.
3. Then press "L" , displayed Ac: 0, this is thermometer error adjustment,  from -5~5 Celsius
4. Then press "L" , dd:0 means show time + temperature + voltage, dd:1 means show time + temperature,  dd:3 show means time + voltage.
5.Then press "L", dF:x mean  cyclic display interval time, do not set dF:0, it will be black screen.
6. Then press "L", LL:x mean bright adjustment.
7.Then press "L", AL:x mean brightness automatic control settings, AL:0 mean not automatic control, AL:1 mean the brightness will automatic swtich 1 level in 19:00~6:00.
