The holiday detector shall be checked with a DC voltmeter at least once each shift to ensure accuracy.
应至少在每次换班时用直流电伏特计检查一次漏涂检测仪以确保其准确度。
The finished joints shall be inspected with a holiday detector set at 8kV DC.
补好的补口应使用带8千伏直流电的漏涂检测仪来检测。
The high voltage endurance test device for switch tube is composed of high voltage pulse generator, high voltage breakdown detector, trigger, auto-controller and DC/AC converter.
开关管冲击耐压装置由高压脉冲产生器、击穿检测器、触发器，及自动控制器、DC/AC变换器等构成。
The improved power output control circuit includes a detector circuit for rectifying an input signal to produce a DC output representing power level of the input signal.
该改进的功率输出控制电路包括检波器电路，用于将输入信号整流产生代表输入信号功率电平的DC输出。
A diode or a 27mH rf choke going to ground provides the dc return so the detector will work. The rf choke does a better job, but they aren't always available. So the diode will work ok.
使用一个二极管或是27mHRF扼流圈接地可让检波单元正常工作，RF扼流圈表现更好，但不一定买得到，所以二极管好些。
