transmitter
4.1.1 Transmitter signals and modes of operation
Signal characteristics
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.
Signal strength
Low output signal strength
Low signal strength conserves the batteries.
High output signal strength
Mode of operation
The
Easyloc Tx
can be used in the following modes:
Symbol
Mode of operation
Induction
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.
Frequency selection
(only
Tx +
)
The
Tx +
version does have two additional buttons for frequency selection:
