岛津XED150L-20X线设备电源供给要求公频单相交流200V,允许波动±10％,如果电源控制或调整电路故障而导至电源供给超出范围,将会在控制台面板透视mA显示处出现F4故障。机器不能使用。如果掌握好电路原理和检查方法,将会很快排除故障。现将我们多次实践中总结经验分析如下。 Shimadzu XED150L-20X line equipment power supply requires a single-phase AC 200V frequency, allowing fluctuation ± 10%, if the power supply control or adjustment circuit failure leads to the power supply out of range, will appear in the console panel perspective mA display F4 malfunction. The machine cannot be used. If you master the circuit theory and inspection methods, you will quickly eliminate the fault. We will now summarize the empirical analysis of many times in practice as follows.
