Red LED Car Digital Thermometer Voltmeter Clock Module w/ Two Sensors

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 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"£¬ press the "S"£¬ "hour" starts flashing£¬ then press the "M"£¬ "hour" increases between 00 to 23 cycles. After setting "hour"£¬ press the "S"£¬ "date" starts flashing£¬ then press the "M"£¬ "date" increases 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.
