Digital Car LED Electronic Clock Time Temperature Voltage 3 In 1 Meter 12V 5-20V

0.56" Digital Electronic Clock Temperature Voltage Meter LED 12V 24V 36v 48v Car 

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 Celsius  ~ 5 Celsius    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  5.Size:Hole size 26 * 58mm thick 23MM            Frame size: 60MMX28MM   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.   Note 1..Please allow 1-2mm error due to manual measurement. Please make sure you do not mind before you bid. 2.The colors may have different as the difference display, please understand.   Package Included 1 x Digital car clock temperature voltage LED 5~60V DIY Car electronic table clock module
