Features :

• Car dash clock operation voltage range is DC 8~30V, temperature measuring range is -40~120 Celsius , voltage measuring range is DC 8~28V.

• Multifunction: it can not only be a car clock, but also be thermometer, besides, it can monitor the voltage of car battery, display mode can be switch by touching key area.

• Two Probes: vehicle thermometer is with two probes, for testing inside and outside temperature of the car.

• LED Display: the time volt temp meter adopts bright LED display, it can be clearly seen even at night.

• Special NOTE: the time is in 24-hour format, temp unit is Celsius . 

Parameters:

• Working voltage range: DC 8~30V

Package Including:

• 1 x 3 In 1 Car Clock (1.5m power cable + 1.5m Sensor)

• 1 x Glue pad

How to use:  

• 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.
