Line and probe location in “Ferrolux” mode
47
The iFS receiver can measure in three different locating modes. In each of these
modes, the signals picked up by the antenna system are processed in different ways.
This means that only the signal received by the vertically arranged antenna is evaluated
in minimum mode, whereas the signals from different antennas are combined with each
other in super max mode. The signal responses of the indicator unit fail in different ways
accordingly. In order to change the currently set method, the menu screen must be
called up by pressing the knob and the
menu item selected. The following methods
are available:
- Maximum method
During line tracing with the maximum
method, only the signal received by the
horizontally arranged antennas of the
receiver is evaluated. When a line is
approached, the signal level increases
slowly and continuously. The maximum
signal is found directly above the line.
- Minimum method
During line tracing with the minimum
method, only the signal received by the
vertically arranged antenna is evaluated.
The signal display and the pitch are
initially greater when a line is approached.
A considerable drop in the signal strength
must be recorded in close proximity. The
signal minimum is located directly vertical
above the line.
- Super maximum method
During line tracing with the super
maximum method, the horizontal
component of the received signal and the
inverted signal of the vertical component
are evaluated. When a line is approached,
the signal strength increases suddenly.
The strong signal maximum is located
directly above the line.
It must be noted that no sidelobe peak is
displayed to the right and left next to the
super maximum.
The signal maximum is extremely
pronounced. In this way, lines lying next to
each other are easier to locate and
identify.
