andym Posted October 1, 2015 Share Posted October 1, 2015 Is it just me, or is there a problem with the video? It keeps cutting out half way through. :-( Andy Quote Link to comment Share on other sites More sharing options...
ruxy Posted October 1, 2015 Author Share Posted October 1, 2015 Just worked again for me , place mouse arrow over picture & click arrow to run. Unfortunately , it does not state exactly what the survey technique is , just low voltage probes to measure ground resistance , also brief glimpse of undersurface results. Seems some sort of earth-loop impedance test. Quote Link to comment Share on other sites More sharing options...
