PARKER派克气缸GDC50-300 3/8测量各点参数时可用普通手缝针焊在万用表的表笔上，以便刺穿漆层直接测量各点，而不用大面积剥离漆层。不要带电插拔各种控制板和插头。在加电情况下，插拔控制板会产生较强的感应电动势，这时瞬间反击电压很高，很容易损坏相应的控制板和插头。检修时不要盲目乱敲乱碰，以免扩大故障，越修越坏。使用逻辑笔、示波器检测信号时，要注意不使探针同时接触两个测量引脚而形成短路。记录时间的的存储大小。必在要多注意有时会有数值的超额。U盘在插入仪表存储数据前要进行格式化处理（按FAT32格式），U盘存储功能需要手动存储，可以到仪表的数据备份画面选择要数据备份的起始时间和接收时间后，然后选择备份有了这些知识。

PARKER派克电磁阀PHS540D-10-24V-DL 3/8其直流回路滤波是电感。它由三部分构成，将工频电源变换为直流功率的“整流器”，吸收在变流器和逆变器产生的电压脉动的“平波回路”，以及将直流功率变换为交流功率的“逆变器“。整流器大量使用的是二极管的变流器，它把工频电源变换为直流电源。也可用两组晶体管变流器构成可逆变流器，由于其功率方向可逆，可以进行再生运转。平波回路在整流器整流后的直流电压中，含有电源6倍频率的脉动电压，此外逆变器产生的脉动电流也使直流电压变动。为了电压波动，采用电感和电容吸收脉动电压（电流）。装置容量小时，如果电源和主电路构成器件有余量，可以省去电感采用简单的平波回路。逆变器同整流器相反，逆变器是将直流功率变换为所要求频率的交流功率。
