As they are not connected, their signal level will never go high.
如果它们没有连接,它们的信号不会变高。
The transceiving signal level sometimes disappeared. It can not guarantee correctness of receiving.
收发信号电平有时没有。不能保证准确接受。
If the input signal level exceeds the programmable threshold, the coarse upper threshold indicator goes high.
如果输入信号电平超过可编程阈值,粗调阈值上限指示器就会变为高电平。
If the temperature drops below a certain level it sends a signal, 'turn on the heat', and that signal stays on until it gets a negative signal to turn off.
如果温度降到一定程度以下时,探测器会发送一个信号,打开加热器,直到加热器再收到关闭的信号,它就会一直开着
