1.第1步:直观入手,选好入口识读该图时,首先应寻找电路边缘处最直观、醒目的元器件,由它们出发可以识读靠近它们的一些单元电路。(1)由电源插头寻找电源输入电路首先,在该图的左下角,可找到交流电源插头P801,它是电源电路的输入端,是直观易读元件。根据电源电路程式,由P801沿着该电源电路的输入电路可以看到,由C801～C804和T801组成抗干扰滤波网络,
1. Step 1: Intuitive Startup, Selected Entrance To read this diagram, you should first look for the most intuitive and eye-catching components at the edge of the circuit, from which you can read some of the unit circuits that are close to them. (1) Searching for the power input circuit by the power plug First, in the lower left corner of the figure, you can find the AC power plug P801, which is the input of the power circuit and is an intuitive and easy-to-read element. According to the power circuit program, by the P801 along the input circuit of the power supply circuit can be seen from C801 ~ C804 and T801 anti-interference filter network,
