3,Pulse of Rotary speed sensor in high level:2~1 2 V

(1)signal lamp
Right-turn signal lamp(Green),Reversing signal lamp(Green)
Brake signal lamp (Red), Parking brake signal lamp /Handbrake signal lamp(Red), Forward signal lamp (Green)
Ⅰ. Left-turn signal lamp(Green)

main function

Ⅰ. Left-turn signal lamp(Green)
Ⅱ. Right-turn signal lamp(Green)
Ⅲ.High beams signal lamp(Blue)
Ⅳ. Reersing signal lamp(Green)
Ⅴ. Brake signal lamp (Red)
Ⅵ. Headlight signal lamp(Blue)

main function

Method of Operation
A,Connect the left-turn signal lamp, right-turn signal lamp, brake signal lamp and Headlight signal lamp to +1 2 V power supply respectively. Moreover, the indicator lamp is supposed to correspond with each luminous point in different color.
B. Backlight is not lit generally. Connect the headlight signal to +1 2 V power supply and the backlight should be lit while needs.
(2) Amp meter
It displays the current in real time with a pointer.
Indication range:0~3 0 0 ( A )
Fluctuation range of Current<4A, error<±2A
Current diverter(3 0 0 A / 7 5 m V) is connected to series in 

the main circuit of power supply. Both the cathode of current diverter and dashboard lead wires directly from the cathode of storage battery.Positive signal of current diverter is connected to positive pole of dashboard, meanwhile, linking both of their negative pole together.

(3) Voltmeter
It displays the voltage by using a pointer.
Indication range: 0~6 0 ( V )/30~9 0 ( V)
Fluctuation range of voltage<1 V, error<±0 . 2 V

main function

Method of Operation:
The pointer indicates the current operating voltage of the storage battery in real time.4,The indicator of panel alarm is able to flicker, while there is only one unit bar shining from the left, along with the sound of buzzer.(Optional);
5,It tests the real-time value of voltage while booting up initially, by showing the 10th unit bar from the left if battery power is full, otherwise it will displays the scales of last power-off state.
Method of Operation:
Coulomb meter indicates the current capacity of electric charge of the storage battery in real time.
(5)The velocity of Autos
It displays the currently rotational speed by using a pointer.
Indication range:0 ~ 6 0 Km per hour
Maximum error: 0.01m per hour
(6) Mileage
Current mileage is displayed by LCD in real-time, and record the last driving mileage before shutdown.
During real-time display without shutdown, the maximum error of mileage is usually within 0.1Km. Furthermore, the maximum error of mileage in a situation of shutdown memory is actually controlled by within 0.1 Km as well.
