Display Elements
The "basic features" of the SR-20 are on by default. Features
can be turned off or hidden to make the display clearer when
doing basic locating in uncomplicated situations.

Figure 4: Common Display Elements
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
•
battery capacity.
Measured Depth/Distance – Displays the measured
•
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).

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 Omnidirectional antenna.
Tracing Line – The Tracing Line represents the
•
approximate axis of the detected field. It represents detected
distortion in the field by appearing less focused. (See page 22
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
degree of distortion present in a signal.
Guidance Arrows – The Guidance Arrows serve to
•
steer the operator toward the center of the detected field, by
showing when the signals reaching the left and right.
