4. Press and hold down the depth button. The depth will be shown on the display.
5. The depth can be verified by lifting up the Locator whilst keeping the depth button depressed.
The depth indication should increase by the same amount that the Locator has been raised.
Limitations of Depth Measurement
There are some situations where it is not possible to gain accurate depth information:
l A curve or bend in the route of the service.
l Close to where the service changes in depth.
l Near to a ‘T’ junction in the service.
l At the very end point of a service.
l At any point where the signal has coupled onto an adjacent service.
l Close to any large metallic objects such as metal fences or vehicles.
l Within 25 m (82’) of the position of the Signal Generator/Transmitter if used on Induction Mode.
l Under reinforced concrete.
l The signal is of poor quality.
l Too close to the Signal Generator/Transmitter or leads if used in Connected Mode.
Depth Measurement: Error Readings of Metallic Services
The Locator may show the following error codes when attempting a Depth Measurement:
1. 000 - The metallic service 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 is not strong enough for the Locator to give a reliable depth measurement.
2. 888 - The metallic service is too deep for the Locator to measure its depth or there is no signal present.
3. OVER - Overload. The signal is too strong for the Locator to give a reliable depth measurement.

Depth Measurement: Metallic Services (DXL4 and MXL4 Locators only)
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. Reading is to the nearest 0.01m.
NOTE AlarmZone™ will activate if the service is too close to the Locator. To measure shallow depths turn AlarmZone™ off
temporarily as described on page 17.
