Set the cursor on the cable length and change the propagation factor so that the pulse echo appears behind the cursor.
- Page 9 This caused a tilting of the reflected pulse and the right end of the cable under test can be determined. Please note the important advice at this method: Do not work with the IRM 7 on live cable! It is very important for accurate measurements to measure the cable under test from both sides.
