The R1000 is designed to display the signal strength visually with a series of four led’s, and
audibly by emitting a pulsed tone. The R1000 is turned “on” and “off”, as well as varying the
amount of signal strength that is displayed, by the Sensitivity Range Switch (off, x1, x2, x3, x4,
x5). The battery led illuminates when the R1000 is turned on. The distance the R1000 is held
from the wire carrying the signal will also vary the signal strength that is displayed. The receiver
can typically detect a signal approximately 1-3 feet away from the wire carrying the signal.
Always try to keep the sensitivity low enough, or high enough, to maintain a maximum of 3
led’s on the indicator so the wire that is carrying the maximum signal is easily identified.
The user must vary the sensitivity to what is considered an acceptable, usable level (usually
3 LED’s), while holding the receiver in the proper direction, to locate the conductor that is
carrying the signal and to identify its direction.
X1000 Transmitter
�� Warning
X1000 – do not connect to live circuits above 300VAC/dC!
The x1000 Transmitter enables tracing of energized circuits up to 300VAC/dC as well as tracing
deenergized lines.
When connected to a closed or energized circuit that allows current to flow, the x1000 will
turn on and off and cause a 17khz current fluctuation that can be detected, by the R1000 in
the “CURRenT” mode, along the circuit path. The signal will flow to the lowest impedance in
the circuit. Usually, the signal is more evident and detected on the conductors going back to
the source (transformer). To increase the signal current travelling to the source (transformer),
disconnect any know loads on that circuit.
When connected to an open circuit, the x1000 will inject a 17khz voltage fluctuation that can
be detected, by the R1000 in the “open” mode, along the circuit path to the end of that circuit.
proper operation of the x1000 Transmitter is confirmed when the R1000 received indicates a
pulsed signal.

�� Warning
do not attempt to replace or remove the battery in the X1000 Transmitter until X1000 is
removed from the circuit and the cord set test leads are removed from the X1000 Transmitter.
The patented battery compartment, on the back of the R1000 and x1000, allows you to replace
the battery quickly and easily. Two holes on the bottom of the compartment accept the round
terminals of a 9 volt battery. The compartment is designed to accept the battery in only one
orientation, so if the door doesn’t close, turn the battery 180° and try again.
