AD2 Oscilloscope - Measure Mains Voltage 110 VAC

[Lars Lindner]

Hi Digilent AD2 Team,

I have a simple question, for which I don't find an quick answer. I want to measure the waveform of a the mains voltage 11VAC using the oscilloscope of the AD2.

What is the best way, to achieve this?

 

Thanks for your help and with best greetings, Lars

Hi,

just wondering, could you simply use a mains transformer with an iron core, e.g. for toy railroad or the like (just remembering this as example that uses AC output without rectifier)? It's not exactly a precision measurement, but the secondary site is properly isolated, making it fairly safe to work with.

Hi xc6lx45,

the idea is not bad, but it will introduce distortions and delays into my measurement signal, through the coils and the magnetization of the iron core. I am looking for a direct measurement method using the AD2.

Thank you and with greetings, Lars

Hi @Lars Lindner

With 10X proble the +/-25V input range is pushed to +/-250V.

Be careful with such high voltages!
You could damage the device, computer and yourself.

Hi Attila, yes thank you. You are totally right :)

What do I have to consider additional, when measuring 110 VAC, using this 10X probes? 

 

Thanks again and with greetings, Lars

Hi @Lars Lindner,

This thread has some additional suggestions, or at least echos some of the ones already here in a bit more detail.

Thanks,
