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� ~ 5�
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� to 120�
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.
