The following procedure describes how to measure the
distance to a short.
NOTE:
Use this feature only when the resistance is 4 kΩ or less
(4 kΩ or less is almost always a hard short). If there is no
hard short on Tip and Ring (A and B), the measurement will
be inaccurate.
To measure distance
1 Connect the Tip (A), Ring (B), and Ground (Earth) leads
to the line under test.
