    Chapter 4 Software Tools Program “Drag-n-Drop” Site Master Software Tools is Windows based. Graphs can “Drag-n- Drop” onto each other. Site Master Software Tools allows quick com- parison of “before” and “after” Distance-To-Fault measurements. Re- cent data is compared to a historical PC database record, which is usually recorded during site installation/commissioning.
