User Manual

1.Place the Power Switch in the TONE position.
2.Pick the pair of wires you wish to trace.
3.Apply the tone to the wires using either the RJ11, RJ45 or the alligator clips.
4.Trace the tone using the Probe
F
actors affecting Tone Volume and Traceability
● Tracing tone is best on wires not connected to a power source. Existing
signals can interfere with the tone signal.
● The tone is always louder at the cable end (not along the cable run).
● If you are tracing a tone and the volume drops, you may have detected a break
in one or both of the conductors.
● To locate the end of a pair of wires, even when the conductors are in a wiring
bundle, see the TONE instructions.
● To fi nd breaks in conductor(s), see the TONE instructions.
● To test a pair of wires for continuity (shorts), see the CONTINUITY instructions.
● To test for the presence/polarity of voltage on a pair of conductors...such as
telephone levels, see the Red/Green LED chart instructions.
When in Tone Mode, the ProTone
sends a tone to a pair of conductors.

TONE SWITCH:
Select steady or alternating
tone (inside case)
TONE MODE
(set power switch to TONE)
TONE: Send tone
The ProTone fi ltered probe detects
the tone from the Tone Generator

Activates the probe's circuitry and
ultrabright LED on the tip.
The "tone" LED is a visual indica-
tion that the tone generator's tone
is detected.
"60HZ" LED warns that 60HZ (AC
voltage) is present and should be
av
oided
TONE MODE
(using the probe)
The red button activates tone sensing and lights the ultrabright LED. Place the
tip of the probe across the cable at various angles until you get the loudest
signal. Filtering eliminates much of the fl uorescent hum from lighting. Use the
60HZ LED for safety and the tone LED for silent operation. Battery: Replace
when 1) the tone is very weak or 2) the probe continually squeals.

Note: The tone generator can send a steady or an alternating tone. The selector
switch is inside the tone generator case.
How to locate wires with the CTX590
CAUTION
Telephones employ a battery voltage of -48VDC for “Ring”. When the telephone
circuit is ringing, the voltage will be much higher (90VRMS on top of the -48VDC).
Be careful not to touch any exposed conductors. Use all of the normal precautions
associated with installing or repairing telephone equipment.
The CTX590 Toner/Probe is a high quality wire locating tool that uses an induc-
tiv
e probe to sense a tone placed on the wires by its associated tone generator.
Plus, the tone generator's red/green LED indicator senses voltage and continuity,
so the CTX590 is useful for tracking down short circuits, telephone central offi ce
connections, polarity and continuity. Because the red/green LED is always active
(regardless of switch position), it can be very informative. See the "Red/Green
LED" chart on the back for details.
● Change the battery(s) when you suspect a weaker than normal tone.
