Network analyser MCA Plus II
MCA Plus II网络分析仪
The MCA Plus II network analyser is an electronic device that allows the reading of the main advanced parameters of a supply network in the true RMS values.
MCA PLUS II网络分析仪是一种可以读取真正的RMS值的供电网络的主要参数的电子设备。
It is specially designed for its easy installation and set up, it requires the connection of four voltage terminals and three current transformers. The capacitive control keypad in the front allows to change the displayed parameters in a few seconds. The MCA Plus II have LCD backlight display for an easy reading in all light conditions.
它是为简化安装和设置方便而设计的，它需要四个电压接线端子和三个电流互感器的连接，前面板上的电容控制界面可以在几秒钟内就实时变化显示的参数。MCA PLUS II具有LCD背光显示，便于在所有光照条件下阅读。
