Section 2 explains the Background. Section 3 explains the HW Diagram. Section 4 explains the HW Reference SCH. Section 5 explains the FW Diagram. Section 6 explains the FW Function List. 2 Background Background of display Function 2.1 Overview On the power meter box, there are 2 keys, display key and program key. The system’s default display mode is auto roll displaying, and each display page delay for 5 seconds. When you put down the display key, display mode will change to manual roll displaying. And if you don’t put down the display key for 30 seconds, display mode will change to auto roll displaying again. 3 HW Diagram Hardware diagram of display unit 3.1 HW Diagram of Display Unit Figure 1.
