Introduction to the SR-20

Installing/Changing Batteries

To install batteries into the SR-20 turn the unit over to ac-
cess the battery compartment. Turn the knob on the
battery cover counter clockwise. Pull straight up on the
knob to remove the cover. Insert the batteries as shown
on the inside decal and make sure they drop to full
contact. Fit the cover into the case and turn the knob
clockwise while lightly pressing down to close. The bat-
tery cover can be installed in either orientation.
Figure 4 – Battery Case
When the SR-20 is powered on, it takes a few seconds
to check the batteries. Until then the battery level will
show as "empty".
CAUTION Do not allow debris or moisture into battery
compartment. Debris or moisture may short the battery
contacts, leading to rapid discharge of the batteries, which
could result in electrolyte leakage or risk of fire.

Folding Mast

To begin operation, unfold the antenna mast and lock the
folding joint into place. When locating is complete, press
the red release lever to fold the antenna mast for storage.
IMPORTANT! Do not snap or whip the SR-20 mast
to open or close it. Open it and close
it by hand only.
NOTE! Avoid dragging the lower antenna node on the
ground while locating with the SR-20. It may
cause signal noise which will interfere with re-
sults, and may eventually damage the antenna.

SR-20 Modes

The SR-20 operates in three distinct modes. They are:
1. Active Line Trace Mode, used when a chosen fre-
quency can be put onto a long conductor using a Line
Transmitter, for locating conductive pipes, lines, or ca-
bles.
2. Passive Trace Mode, used for tracing electrical lines
that are already carrying 60 Hz current (U.S.), 50
Hz current (Europe), or radio frequencies.
3. Sonde Mode, used for locating Sondes in pipes,
conduits, or tunnels that are nonconductive or cannot
otherwise be traced.
Note that the two Tracing modes, Active and Passive,
are identical except for the frequencies used. No trans-
mitter is used in Passive Trace mode.

Display Elements

The "basic features" of the SR-20 are ON by default.
They can be customized easily to suit the user's re-
quirements.
