四、维修注意事项1.采用隔离变压器由于电源板与市电输入直接相连接,维修中一旦人体不小心碰到“一次”电路,就会发生触电事故;另外,采用示波器测量波形时,如果接地或测试点弄错,还会烧坏示波器。因此建议使用1∶1的隔离变压器进行维修。如果有调压功能的隔离变压器更好,可通过电 Fourth, maintenance precautions 1. The use of isolation transformers as the power supply board and the mains input directly connected to the maintenance of the human body once inadvertently encountered “a ” circuit, there will be electric shock; addition, the use of oscilloscope waveform, If the ground or test point is wrong, but also burn the oscilloscope. It is therefore recommended to use a 1: 1 isolation transformer for service. If the voltage regulator isolation transformer better, by electricity
