Theory of Operation

The CS-8000 transmitter is intended for connection to an electrical line (up to 750 volts) or
other metallic object. The transmitter signal consists of a controlled frequency with a specific
modulation and timing that is different for live and open circuits. This composite signal gives it a
specialized signature.
The transmitter signal generates a corresponding magnetic or electrostatic field signature around
the conductor being traced. This field signature is present the entire length of the conductor,
including breakers, fuses, switchgear, and transformers.
The CS-8000 receiver is tuned and programmed to pick up only the field signatures produced
by the transmitter. To be received, the signal must have this exact frequency, modulation, and
timing. This feature greatly reduces the possibility of interference from electrical noise, which is
often caused by lamps, appliances, fluorescent fixtures, or machinery that is on the same line.
Both the transmitter and the receiver are microprocessor-controlled for maximum ease of use
and accuracy.

Basic Operation

These instructions provide the user with a basic understanding of how the unit functions. These
tests are best performed at a desk or bench.
Transmitter
1. Push and release the Power button. The Power LED illuminates, indicating unit power and
signal being sent.
2. Plug the unit into any energized outlet. The Live Line LED also illuminates, indicating that the
transmitter is connected to an energized circuit.
3. Unplug the unit. Push and release the Power button to turn the unit off.
Receiver
1. Push and release the Power/Signal Reset button to turn the receiver on.
2. The Transmitter Signal Indicator (segments of the red oval) will rotate, indicating the receiver
is searching for a signal. The display will indicate the unit is set to "BREAKER MODE." A
small blue bar will appear on the left side of the screen, indicating there is no signal strength
available. A red bar at the end indicates the maximum signal the unit has received since
Signal Reset. The unit will also read "AUTO GAIN", which is the default mode when the unit
power is turned on.
3. Push and release the Mode Selector button. Indication will change from "BREAKER MODE"
to "SEARCH MODE." This button toggles between the two available settings. Whenever this
button is pushed, the signal strength automatically resets.
4. Push and release the up or down arrow button. Indication will change from "AUTO GAIN" to
"MANUAL GAIN."
5. Push and hold the Power/Signal Reset button for approximately one second to set the unit
back to "AUTO GAIN."
6. Push and hold the Power/Signal Reset button to turn the receiver off.
