电压测量就是测量待修仪器中的有关电路的各种直流电源电压,以及各电子器件的检测点上的直流工作电压。所用的测量仪器应为内阻较高的三用表或数字式电压表。至于一些集成电路的软故障,则可用IST5700C集成电路在线测试仪。测量电压法是检查电子仪器故障的基本方法。用此方法检查电子仪器故障时,应注意三点:1.注意安全,防止触电;2.克服
Voltage measurement is to measure various DC power supply voltage of the relevant circuit in the instrument to be repaired and the DC working voltage at the detection point of each electronic device. The measuring instruments used should be higher internal resistance meter or digital voltmeter. As for the soft fault of some integrated circuits, IST5700C integrated circuit on-line tester can be used. Measuring voltage method is to check the basic method of electronic equipment failure. This method of checking electronic equipment failure, should pay attention to three points: 1. Attention to safety, to prevent electric shock; 2. Overcome
