Fluke 1912A Description:福禄克1912A描述:

　　This Freuquncy Counter's channel B input has a circuit which automatically monitors the input and gives you instant warning in the form of zero readout whenever you input signals falls below the sensitivity threshold of the trigger circuit.这Freuquncy计数器的B通道输入具有自动监控电路，输入，让您在零读出只要你输入信号低于触发电路的灵敏度阈值的形式即时警告。

　　When the signal level returns to an acceptable level, the counter locks on for a correct reading.当信号电平恢复到可接受的水平时，计数器将锁定正确的阅读。
