Do you use them in France? In America inductive type meters don't read DC. The device would have to be very "special" indeed. It would also be very susceptible to local magnetic fields (much like a compass) and would have to be shielded and have provisions for hookup to earth ground or some low reference for the shield.

Granted, I was too literal in saying that it is impossible to construct such a device (or that they might indeed be available), but the clamp-on ammeters that someone asking questions here might have will not measure DC Current through the inductive (clamp-on) coil.

I am not getting in a flame battle here -say what you want. I am sure that I could learn something from you. If there is a common field test instrument that you are speaking of -please post so that I can investigate the instrument for my use at work.
