The receiver light may be on, dim or even off. Because some power is lost in the digitizer, the link cable becomes more sensitive to the effects of earthing. If the led if off, you can do a test to make confirm that a scalar field is present. Go to system tab and select “Display GX current and angle”. The graph in the control tab will then display the current on the selected generator. Placing your hand in the scalar field should influence the graph, proving a scalar field is present.
