Pipe Tracing using a Sonde:
Tracing a Sonde
The technique used to determine the position of a Sonde is always
the same irrespective of which Sonde is being used.
Before inserting the Sonde into the pipe it is best to set up the
Locator so that the sensitivity is correctly adjusted to suit the pipe
depth. This is easier to do when the Sonde is visible at the bottom
of the manhole rather than already in the pipe.
1. The blade of the Locator must be held IN LINE with the Sonde
at all times.
2. Turn the Locator to Generator Mode/ Transmitter Mode, switch
on
(
and on the MXL2 select the correct frequency
)
; ‘CF’ for 33kHz
Sondes, ‘8kHz’ for 8kHz Sondes and ‘LF’ for 640/512Hz Sondes).
Check the Battery Level Indicator to confirm the Locator batteries
are usable. Replace if necessary.
NOTE
This is at 90 degrees to the way in which the Locator is held for most other locating tasks.
