Line Tracing The Seesnake Pushrod - RIDGID LT1000 SeeSnake Manual De Operador

SeeSnake® LT1000
Figure 26 – Locating the Sonde
To turn the SeeSnake Sonde ON while using the LT1000,
press the Sonde Key . A Sonde icon will appear on
the display while the Sonde is ON. The display may also
show some lines of interference from the Sonde's trans-
mission. These will vanish when the Sonde is turned
OFF by again pressing the Sonde Key
The most workable approach to tracking the Sonde is
to run the pushrod into the pipe about five or ten feet /
1,5 to 3 meters and use the locator to find the Sonde's
position. If desired, you can then extend the pushrod
a similar distance further down-pipe and locate the
Sonde again starting from the previous located posi-
tion. To locate the Sonde, turn the locator ON and set
it to Sonde mode. Scan in the direction of the Sonde's
probable location until the locator detects the Sonde.
Once you have detected the Sonde, use the locator in-
dications to zero in on its location precisely. For detailed
instructions on Sonde locating, consult the Operator's
Manual for the locator model you are using.

Line Tracing The SeeSnake Pushrod

The LT1000 also enables you to trace the line of the
pushrod underground, using a standard RIDGID loca-
tor such as the NaviTrack® II, the Scout™, the SR-20 or
the SR-60. To line-trace the SeeSnake pushrod, simply
connect a line transmitter with one connector well-
grounded to the grounding stake and the other con-
nector clipped to the Transmitter Clip-on Terminal. The
Transmitter Clip-on Terminal is a metal lug located just
under the left end of the keyboard area as shown in Fig-
ure 27.

Figure 27 – LT1000 Transmitter Clip-on Terminal
Set the line transmitter and the locator to the same fre-
quency, such as 33kHz and use the locator to trace the
line (Figure 28). The camera's built-in 512Hz Sonde may
be on at the same time, and if your locator is equipped
. with SimulTrace™ dual-frequency capability, you can
follow the pushrod all the way to the camera's location
and then detect the Sonde in the camera as you ap-
proach it above ground.
If you don't have the SimulTrace™ feature, use a line
transmitter and a locator to line-trace the pushrod.
When the signal fades, switch the locator to Sonde
mode at the frequency of the in-line Sonde, usually
512Hz. Pick the signal up from where the line-trace
frequency started to weaken and zero in on the in-line
Sonde. Because locating frequencies from transmitters
can cause distortion of the image on the monitor, it is
best to turn Sonde and line transmitters OFF while in-
specting the interior of a line and turn them ON only
when ready to do a locate.
