Depth Measurement of Non-Metallic Pipes
using Sonde s/ Plastic Pipe Tracer s/ Flexible Tracer (DXL3 only)
NOTE The following instructions apply equally to all Sondes, Plastic Pipe Tracers and the Flexible Tracer in End Tracing Mode.
NOTE The depth shown is that of the Sonde and NOT of the pipe.
1. Pinpoint the exact position of the Sonde or Plastic Pipe Tracer / Flexible Tracer tip.
Take care to ensure that you are not over one of the two ‘ghost’ signals in front of and behind
the true position.
2. Rest the DXL3 on the ground, keeping it vertical and IN LINE with the Sonde or Tracer tip.
3.
IMPORTANT. Push the depth button TWICE and hold on the second push, to select
Sonde Depth Mode.
The word ‘SONDE’ will flash on the display and the depth will then
be displayed (see picture). If the word ‘SONDE’ is not displayed then the depth reading
will not be accurate.
Depth Measurement: Error Readings of Non-Metallic Pipes using Sondes/Plastic Pipe
Tracer s/Flexible Tracer
The Locator may show the following error codes when attempting a Depth Measurement
to a Sonde or the tip of a Plastic Pipe Tracer or Flexible Tracer:
1. 000 - The Sonde/Plastic Pipe Tracer/Flexible Tracer is too shallow for the Locator
to obtain an accurate depth, less than 0.8m (31inches). It should be possible to calculate
the depth by raising the Locator a set amount and then carrying out the Depth Measurement again.
2. 888 - The Sonde/ Plastic Pipe Tracer/Flexible Tracer is too deep for the Locator to measure its depth
or there is no signal at all present.
3. LO - The signal from the Sonde/Plastic Pipe Tracer/Flexible Tracer is not strong enough for the Locator
to give a reliable depth measurement.
4. OL - Overload. The signal from the Sonde/Plastic Pipe Tracer/Flexible Tracer is too strong for the Locator
to give a reliable depth measurement.
