be saved on the screen in 

a smaller box until a new

Normal Range: A good pair should have the T-G and R-G 

within about 2% of each other. If they are not within 2%, the 

shortest distance will be the location of the fault and the other 

distances will not provide accurate distances. Typically this will 

be an open ground bond or a broken Tip or Ring.
Note: “Opens” is more accurate if other cable pairs are active.
