Estimating Depth and Current of a Utility
6.1
Utility Line Depth
☞
For utility line depth, the locator needs to be used in conjunction
with a signal transmitter. Refer to "5.4 Using the Transmitter in
Induction Mode" and "5.5 Using the Transmitter in Connection
1.
Set the locator to the required Signal
Transmitter frequency.

2.
Position the locator directly over and at
90° to the direction of the utility.
☞
Ensure that the locator foot is
directly on the ground.
☞

4.
The Line Depth screen displays the
measured depth.
DD130 series: The measured current
(mA) is subsequently displayed.
☞
Lift the locator off the ground
by approximately 15 cm/6 in
and take a second depth read-
ing. This depth reading should
confirm the added height.

5.
The depth is calculated as distance to the
centre of the utility! Allowances should
be taken into account.
Note the difference between a and b!
a
