Battery Power:
the circuit of the combination meter is directly powered by the battery, is not controlled by the ignition switch and the light circuit;
ON power:
the power received by the meter when the ignition key is in the ON gear;
Ignition: turn the ignition key from ON to START;
High Level: 29V~32V;
Low Level: -1V~1V;
CAN loss: The corresponding CAN signal is not received within 3s by the meter.
ICU: CAN node name of this meter, which also refers to the software processing part of the meter in this datasheet;
Mechanical Zero Position: the limit position that the stepper motor pointer can reach to the zero position;
Null Indicator: the displayed zero position of the stepper motor pointer points in the meter.
