In this method, shown in Figure 1-20, a current source generates current (I), which flows through the unknown resistor (RX).

在图1 - 20所示的这种方法中，电流源产生的电流(I)流过未知电阻器(RX)。

When you receive a signal on the current channel, the RX icon is displayed. (See "LCD SCREEN" for details) and red LED indicator lights up.

当您收到在当前渠道时的一个信号， RX象被显示。（参见“LCD屏幕”关于细节）和红色LED显示灯。

If you receive a signal on the current channel then the icon RX (BUSY) will appear. (See "LCD-screen" for more information).

如果您收到一个信号，对当前频道，然后该图标的RX(繁忙)会出现。(见“液晶屏幕”的更多信息)。
