That is in resonance with the detector when the probe contacts are closed, and not when they are not. I assume there is the rest of an LC bridge circuit in the transmitter, an oscillator, precision (op-amp) rectifier and level detector. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
