Find ground loop in this very simple set of interconnected
instruments shown below.
instruments shown below.
1st step:
Link both Exciter and Detector to a power cord (below). If Detector red LED illuminates, this power cord is part of a ground loop!
Link both Exciter and Detector to a power cord (below). If Detector red LED illuminates, this power cord is part of a ground loop!
2nd step:
Leave Exciter linked to the power cord and move Detector to link other cables (below). If Detector red LED illuminates, then linked cable is part of same ground loop as power cord! Move Detector to trace ground loop path. If ground loop current splits into two or more branches, meter indicates branching ratio.
