后备机种市电侦测方法 市电频率范围： 50Hz：46Hz~54Hz 60Hz：55Hz~65Hz 市电波形衰减率：84/1 市电AD转换公式： (1)市电AD转换值 = ((Vip / 84) / 5V) * 256 + Voffset (2)如：以市电电压100V为例，其所对应的AD转换值： AD转换值 = ((100 / 84)/ 5V) * 256 = 61T； -City reserve aircraft detection methods < 1> City frequency range: 50Hz: 46Hz ~ 54Hz 60Hz: 55Hz ~ 65Hz < 4> City waveform attenuation rate: 84/1 < 5> City AD conversion formula: (1) City AD conversion value = ((Vip/84)/5V)* 256+ Voffset (2) such as: voltage 100V power to the city as an example, it corresponds to the AD conversion value: AD conversion value = ((100/84)/5V)* 256 = 61T
