4.2 CONNECTION AND INITIAL USE OF TRANSMITTER TX5000
4.2.1 Transmitter signals and operation modes
The type and strength of the output signal can be configured by the user as follows to
meet the specific requirements of either the line to be located or the site to be surveyed:
Symbol Signal type
Pulsed signal
As it is more easily distinguished from other signals, the pulsed signal
is helpful for locating when there is interference within the frequency
range of the transmitter. This also helps to conserve the batteries
Depth measurements cannot be made using a pulsating signal
Continuous signal
This signal type has to be activated before a taking a depth
measurement
Symbol Signal strength
Low output signal strength (0.1W)
Low signal strength conserves the batteries
High output signal strength (0.5W)
Symbol Operation modes
Inductive connection
In this mode of operation the transmitter's signal is emitted through
the integrated antenna and is thereby inductively coupled with any
metallic lines located within a certain radius
Direct connection
In this mode of operation the signal is directly coupled with a metallic
line via the measurement cable which is connected to the jacks on
the front panel of the transmitter. Transmitter clamps, alligator clips or
power socket adapters (for example) may be used to connect the
measurement cable to the lines
