Operating Instructions
CAUTION: Always test the probe and transmitter for proper operation before use.
CAUTION: The transmitter is not designed for use on energized circuits. Connecting to
any voltage source greater than 52VDC may damage the circuit.
Note: The transmitter will not generate a signal into a short circuit.
Self Test
1. Set the transmitter power switch to the Tx
position.
2. Adjust the probe sensitivity to MAX (+)
clockwise position.
3. Press and hold the probe power button.
The red LED will light.
4. Move the probe close to the transmitter
cable and note that the audible trace tone
and sensitivity adjustment perform normally.
Cable/Wire tracing
1. Select the transmitter termination required. Permanently attached are RJ11 and RJ45
connectors. Plug the RJ45 connector into the adaptor cable to obtain CATV type F
connection or alligator connectors.
2. Connect the transmitter to the cable
a) For cables terminated at one end, connect the red alligator clip to a wire and the
black alligator clip to equipment ground
b) For unterminated cables, connect the red alligator clip to one wire and the black
alligator clip to another wire.
c) For cables with modular connectors, plug the RJ11, RJ45 or type F connectors
directly into the mating cable connectors.
3. Set the transmitter power switch to the Tx position.
4. Adjust the probe sensitivity to MAX (+) clockwise position.
5. Press and hold the probe power button. The red LED will light.
6. Hold the insulated probe tip against the wire in question to pick up the signal
generated by the transmitter.
7. Rotate the volume/sensitivity control on the top of the probe for the appropriate level
and sensitivity to identify and trace the wire.
8. The tone will be the loudest on the wires directly connected to the transmitter.
Telephone Line Test
1. Switch the transmitter to the OFF position
2. Insert the modular plug into the phone line.
3. Observe the “TEL. LINE” LED for the following conditions;
a. Bright Green: Working line, not in use, correct polarity
b. Dim Green or Red: Working line, not in use, polarity undetermined
c. Bright Red: Working line, not in use, reverse polarity
d. Bright Green/Red flashing: Working, ringing line
