4. Press and hold down the depth button. The depth will be shown on the
display, measured in metres.
5. The depth should be verified by lifting up the locator whilst keeping the
depth button depressed. The depth indication should increase by the same
amount.
Limitations of Depth Measurement
- There are some situations where it is
not possible to gain accurate depth information:
●
A curve or bend in the route of the service.
●
Close to where the service changes in depth.
●
Near to a “T” junction in the service.
●
At the very end point of a service.
●
At any point where the signal has coupled onto an adjacent service.
●
Close to any large metallic objects such as metal fences or vehicles.
●
Within 25 metres of the position of the Signal Generator if used on
Induction mode.
●
Under reinforced concrete.
●
The signal is of poor quality.
●
Too close to the Signal Generator or leads if used in Connected mode.
Depth Measurement
4.
NOTE The depth shown will be to the centre of the service and is not the depth of cover. This is of greater
significance on large diameter pipes. Accuracy is to nearest 0.05m. Range is 0.2m to 3.0m.
