7.4 How to Locate a Service Using the Sonde
Attaching the Sonde to a
drain rod
Once the function of the Sonde has been checked with a Locator set to the same operating
mode it can be attached to drain rods or other means of guiding it into the service being
traced.
Locating the Sonde
1. Walk in line with the suspected direction
of travel observing the display. The
signal strength indicator will rise and fall
as you pass over the ghost signal at the
back of the Sonde, the peak signal
directly over the Sonde and the ghost
signal at the front. The numeric signal
strength indicator will display its highest
value when detecting the peak signal.
2. Retrace your steps and position the
locator directly over the peak signal.
Move the locator left and right until the
highest numeric reading is obtained.
This reading will indicate the Sonde’s
precise location.
