The display screen in Active Line Trace, Passive Line
Trace or Sonde mode will show the following features:
Active View Area – The area inside the circle on the
SR-20 display where the Tracing Line, Guidance Arrows,
and crosshairs are displayed.
mA Current Strength – Proportional to current on the
line. Switches to Signal Angle when Signal Angle is
greater than 35°.
Signal Angle – Field tilt from the horizontal; angle
toward the field's center; numeric value displayed in
degrees.
Battery Level – Indicates level of remaining bat-
tery capacity.
Measured Depth/Distance – Displays the mea-
sured depth when receiver is touching the ground directly
over signal source. Displays computed distance when
the antenna mast is pointed at a signal source in some
other manner. Displays feet/inches (U.S.A. default) or
meters (European default).
Mode – Icon for Sonde
(Passive Line Trace) , or Radio Frequency
Frequency – Shows current frequency setting in hertz or
kilohertz.
+ Crosshairs (Map Center) – shows operator's position
relative to the target center.

In Active Line Trace Mode, the following features will also
be displayed:
Proximity Signal – Numerical indication showing
how close the signal source is to the locator. Displays
from 1 to 999. (Line Trace modes only)
Signal Strength – Strength of signal as sensed by
the lower antenna mode.
Tracing Line – The Tracing Line represents the
approximate axis of the detected field. It represents de-
tected distortion in the field by appearing less focused.
(See page 25 for information on setting the sensitivity
and how to enable or disable the distortion response in
the Tracing Line.)
Distortion Line – If the normal distortion response of
the Tracing Line is disabled, a second line is shown,
which represents the signal from the upper antenna node.
By comparing the two lines, the user can estimate the de-
gree of distortion present in a signal. (See page 26.)
Guidance Arrows – The Guidance Arrows serve
to steer the operator toward the center of the detected
field, both arrows are displayed on the screen when
crossing the center of an undistorted field. If the signals
are unequal, the Guidance Arrows show which way the
field appears to be relative to the receiver.
NOTE! The Tracing Line reflects the approximate axis of
the conductor being traced. The Tracing Line
will appear to grow unfocused in proportion to the
distortion in the field being detected.
It represents the best possible calculation of
the location and bearing of the line combined
with the degree of distortion sensed by the re-
ceiver's Omnidirectional Antennas.
The distortion response feature of the Tracing
Line can be disabled. When it is, the screen
displays two lines – a solid Tracing Line (
representing the axis of the detected conductor's
field as seen by the lower antenna node, and a
distortion line (
as seen by the upper antenna node.
(For more information about distortion, see
pages 12 and 26.)
