0.3% of FSD error? Isn't that quite good for this sort of device? One I

If it were the clamp-on DC range, it would be good. But the AC clamp-on
is just a transformer secondary. It SHOULD read 0 with nothing there!


If it were just a plain winding that might be so. But it has to open to
allow fitting round a cable.
