the locator emits a tone and the signal
strength indicators rise and fall as you
pass over the utility.
Return to the position where the Locate
screen shows a peak reading. Mark the
position of a utility with marker paint,
pegs, flags or something similar.

Never drive pegs into the
ground over the utility!

Using the Transmitter in Connection Mode
5.5.1
General Information
Connection mode is the most efficient way to apply a signal to a utility. The
cable set of the transmitter or any of the available accessories are connected
to the utility which is to be traced or identified.
☞
Whenever possible, use the transmitter in connection mode, espe-
cially for taking a depth reading.
☞
The Numeric Peak Indicator can be used to indicate multiple utilities
or to assist tracing. The utility with the maximum value is typically the
one connected to.
☞
The black connection cable can be connected to other metallic struc-
tures which go into the ground, such as iron grids or metal covers of
access chambers.
☞
In dry conditions it may be necessary to add water around the earth
point to get a good connection.
☞
When using the connection cable set, examine the connection points
and remove contamination if a continuous audible output is not ach-
ieved.
