signal drop to a lower level but not necessarily end. Either the
speaker or the analog meter on the receiver will indicate this drop.
The faulted area will also produce a "hot spot" of signal right at the
cut as the signal is lost to ground.
Be sure the cable or wire you are tracking is grounded. The signal
needs a path to return to the ground stake and without it, you will
not get a good locate. A bad ground is indicated on the transmitter
analog meter when the needle cannot achieve a 4 or better even
at full power. In many cases, a direct buried cable fault will provide
this grounding and allow for a locate.
Do not let the receiver level go above 10. You are looking for a
drop in signal and you may not see it if the analog meter is
pegged to the right.
The greater the damage, the greater the drop off in signal.
Conversely, minimal damage or weak grounding will show little
change and are sometimes so small as to be un-locatable with the
Pro700. Practice and experience will help immensely in this task.
Finding Solenoids and Valves
Finding solenoids and the attached valves is easy to do. If you
want to find a particular valve, connect the red lead of the
transmitter to the station wire leading to that valve and the black to
ground as described above. Connect the Pro700 as above and
begin your locate. When you reach the point where a
valve/solenoid is located, the signal will expand into a large
(approx 2-4ft) diameter area of signal. This is your indication that
you are over a valve or solenoid. Additionally, the signal should
not continue past this point.
There may be more than one valve on the cable being traced.
You may wish to continue past the first valve located to determine
if other valves are also located on this wire.
