2 Green LED Display Digital Car Thermometer Voltmeter Clock Module

Highlight: this device has two temperature sensors£¬ for inside car and outside car£¬ the sensors are 150cm and 300cm. Features: 1. Set the time£¬ temperature£¬ voltage£¬ three functions in one 2. Manual error correction function with a temperature setting range -5¡æ ~ 5¡æ 3. With backup battery£¬ power-down time to continue to go Electrical Characteristics: 1. Input voltage 5 ~ 60V 2. Voltmeter range 5 ~ 60V£¬ the measured voltage is the input voltage. 3. Temperature measurement ranges from -40¡æ to 120¡æ 4. Working current is about 30MA How to use: Keyboard plate has two keys: S (Setting)£¬ M (Mode); 1. Under normal use£¬ press the "S"£¬ "minute" starts flashing£¬ then press the "M"£¬ "minute" increases between 00 to 59 cycles. After setting "minute" and then press the "S"£¬ "hour" starts flashing£¬ it increases between 00 to 23 cycles. After setting "hour" and press Down to adjust the date£¬ then "date" starts flashing£¬ press UP to increase between 1 to 31 cycles 2. Then press "S" £¬ displayed AC: xx and Ac:xx £¬ (AC means temperature sensor 1£¬ Ac means temperature sensor 2. xx is the value to be corrected temperature value in degrees. Press the "M" to adjust the temperature error correction value£¬ ranging from -5 ~ 5 £¬ a positive number is increased£¬ the negative is reduced. After correcting the temperature error£¬ and then press "S" to save all the data£¬ and return to normal display.) 3. Then press "S" £¬ dd:0 means time + temperature 1 + temperature 2 + voltage£¬ dd:1 means time + temperature 1 + temperature 2£¬ dd:2 means time + temperature 1 + voltage£¬ dd:3 means time + voltage 4. Then press "S"£¬ DF means cyclic display interval time.
