Questions about USA system

Thanks again. I’m comfortable with setting up a LAMP box and installing some additional software, but we’ll see. I think I’ll just get the base and work from there.

That accuracy is the slope over the working range. But at the ends, accuracy goes out of the window. At the top, the output droops as the c.t. saturates; at the bottom, the power needed to magnetise the core screws everything up.[/quote]

So to know the difference in the 100A and 60A, for accuracy at the bottom end, I take it I would want to know if the cores were different, which would fewer amps to get going. If the cores were the same, then nothing is gained.
