What does happen if you connect a multimeter without COMmon ground?
Like in this question (Why does a permanent, non-moving magnet, stuck to a long piece of metal generate a voltage?) How would a multimeter react if you connect the leads to the current and the volt measure inputs.
- Just "in the air", so not connected to anything
- if measuring DC/AC voltage
(second one beeing probably more destructive)
Is there a fuse to prevent disaster? I'm especially interested in what components are responsible for the output (the chip, the circuit board, etc.)
