501
Identification
The Model 501 is designed to locate the path and depth of buried cable, service wires, metallic
pipe or conduit and locate the end of a cut cable.
Transmitter
The transmitter is housed in an aluminum case and is powered by eight (8) 1.5V AA batteries.
The transmitter has an on/off control knob which is also used to adjust the output level and a
light emitting diode (LED) indicating the battery condition. In addition, the transmitter has an
automatic shut-off feature after 1.5 hours of non-use. Effective range is greater than 4000 feet
in length and for depths up to 7 feet.
Receiver
The receiver is encased in an aluminum housing, mounted with an antenna and is powered by
one (1) 9V battery. Like the transmitter, the receiver will automatically shut itself off after 1.5
hours of non-use. The receiver has a speaker for listening to the signal, a meter for monitoring
the signal level, a headset jack, an on/off volume control knob and an antenna for detecting the
tone over the cable.
Carrying Case with Inductive Antenna
The case is used for storing and transporting the Tracker II system and is constructed of
vacuum formed polyethylene. The case also includes an easy, quick reference operation guide
on the inside of the lid.
Cord Set
An 8 foot pair of leads with plugs and clips is included for connecting the transmitter to the
cable or pipe.
Inductive Coupler
The inductive coupler induces a tracing tone on a cable, wire or pipe by clamping around it.
Optional Headset
The headset can be used to monitor the received signal in high noise level areas and is plugged
into the receiver jack provided.
Operation
Testing Transmitter Batteries
Plug cord set leads into transmitter and clip leads together. Turn transmitter control on and
rotate fully clockwise. A bright LED indicates enough battery power. Refer to the "Maintenance"
section for battery replacement.
Connecting Transmitter Leads
IMPORTANT: The transmitter is protected against damage from inadvertent direct connection
to voltages up to 250 VAC. However, direct connection to energized cable is not recommended.
The inductive coupler Model IC-1 is included for such applications.
Shielded Cable (Coaxial): Connect one lead to the shield and the other lead to one wire
within the cable.
Unshielded Cable: Connect each lead to separate conductors within the cable.
Single Conductor: Connect one lead to the conductor and the other lead to earth ground via
screwdriver.
Metallic Pipe or Conduit: Connect one lead to the pipe or conduit and the other lead to
earth ground via screwdriver.
Gas Pipes: Connect one lead to the "IN" line of the gas meter and the other lead to the "OUT"
