Radiodetection rd7000+ Bedienungsanleitung Seite 14

Connecting the transmitter to a pipe or line requires the use of a direct connection lead
and a ground stake to complete the circuit.
WARNING! Direct connection to live conductors is POTENTIALLY LETHAL. Direct
connections to live conductors should be attempted by fully qualified personnel only
using the relevant products that allow connections to energized lines.
Induction
The transmitter is placed on the ground over or near the survey area. You select the
appropriate frequency. The transmitter will then induce the signal indiscriminately to
any nearby metallic conductor. In induction mode, using higher frequencies is generally
recommended as they are induced more easily onto nearby conductors.
Clamp
The optional signal clamp can be used to apply the transmitter signal to an insulated live
wire or pipe up to 8.5"/215mm in diameter.
WARNING! Do not clamp around uninsulated live conductors.
WARNING! Before applying or removing the clamp around a power cable ensure
that the clamp is connected to the transmitter at all times.
Refer to the Signal Clamps paragraph in the Using Accessories section.
Locating RF Markers
The RD7000+ locator enables users to locate most common RF utility markers. These
are also referred to as Electronic Marker System (EMS) and Omni markers.
To enable marker locate mode lower the marker loop antenna. To disable the marker
locate mode fold the loop antenna up.
Marker types
The RD7000+ can detect 9 different RF Markers, as shown in the table below.
