Hi,
I got two lab power supplies, which have amp and voltage control.
Now I need to know whether the ground on them is floating or not. I mean that there is no direct connection from the minus pole to electricity network. I don't know the right word for it in English. But what I am after is that do they disconnect the device connected to them from the electrical network with a transformer.
Hope someone knows how to measure that somehow. They are installed in tight place and I would not rather to dig them out. Air circulation is adequate - I think...
Best Regards Kari
