3. SPECIAL FAULT LOCATING PROBLEMS
1. Finding faults under concrete. Dissolve approximately 1/4 cup of salt in one gal
lon of water and soak two large sponges in the salt water.Wrap the sponges over
the end of each probe and attach with a rubber band. Now proceed as described in
2.7. Re-soak the sponges often and dampen the area where sponges are placed.
2. Obstructions over the drop. It is not necessary to be directly over the drop path
to indicate the fault location.The drop path could be under a street, driveway, or
sidewalk. In this case, if the soil parallel to the drop path can be probed (up to 15
feet away), you can locate the fault. Accuracy will not be exact compared to
following the path.
3. Multiple faults. Multiple faults will cause the receiver to reverse at each fault; the
most solid fault will produce the strongest signal, kick, or reversal. The best policy
is to repair the first fault you locate and then reconnect the Pulser and locate the
next one, until you have cleared all the trouble.
4. High resistance faults. A very high resistance may produce a weak kick. To help
make this fault easier to locate, simply turn the sensitivity all the way clockwise.
Pouring water on ground stakes will increase sensitivity.
5. Long distances to the fault. Extreme distances between the transmitter and the
fault can cause you to lose signal for a distance between the transmitter and the
fault. This is no real problem. Note the distance from the transmitter to the
point you lose signal.You will pick the pulse up the same distance from the fault.
For example, we will use a distance of 100 feet between the probing. The pulse
will be received 100 feet on either side of the fault.
