Depth Measurement:
using Sondes / Plastic Pipe Tracers / Flexible Tracer
NOTE The following instructions apply equally to all Sondes, Plastic Pipe Tracers and the Flexible Tracer in End Tracing Mode.
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 Locator 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 be inaccurate.
Depth Measurement: Error Readings of Non-Metallic Pipes using Sondes / Plastic Pipe Tracers /
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 0.1m (4"). It should be possible to calculate the depth by raising
the Locator a set amount and then carrying out the Depth Measurement again. The '000' Error
will also display if the signal from the Sonde/ Plastic Pipe Tracer/ Flexible Tracer is not strong enough
for the Locator to give a reliable depth measurement.
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. OVER - Overload. The signal from the Sonde/ Plastic Pipe Tracer/ Flexible Tracer is too strong
for the Locator to give a reliable depth measurement.
NOTE Alarm Zone™ will activate if the Sonde/ Plastic Pipe Tracer/ Flexible Tracer is too close to the Locator.
To measure shallow depths turn Alarm Zone™ off temporarily as described on page 17.
