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.
