How to test for continuity using the CTX590

1. Pick the pair of wires you wish to test for continuity.

2. Place the switch in the CONTINUITY position.

3.Attach the tone to the wires using either the RJ11, RJ45 or the alligator clips

4.If the Red/Green LED lights, continuity exists on the pair. Note: You can verify whether you are in CONTINUITY mode by touching the alligator clips together. Remember, if continuity exists across two conductors purposely, it is called "bridging". If it is not by design, it is called a "short" circuit.

Use this mode to detect whether

a pair of wires has continuity.

This test does not require the

use of the probe.

RED/GREEN LED CHART

Voltage, polarity and continuity tests: The Red/Green LED is active in all three switch positions. See the following chart for the LED's meaning:

The Red/Green LED indicates voltage, polarity and continuity

Switch position

WIRE LOCATOR ALL WIRE TYPES

MODEL CTX590

LED color Tone Off Continuity

Red Positive voltage Positive voltage Yes Green Negative voltage Negative voltage NA Alternating AC voltage AC voltage NA

In the TONE mode, the tone itself causes the red/green LED to indicate AC voltage (the tone itself is an AC signal). So, for voltage/polarity tests, use the OFF position.

How to determine polarity: Positive voltage on the red clip in relation to black clip is

e polarity; as is pin 3 in relation to 4 (RJ11); and pin 4 in relation to 5 (RJ45).

When checking telephone polarity, a green LED is correct telephone polarity and a red LED is reversed polarity.

Detect telephone and modem connections using the Red/Green LED

Phone pairs have a “tip” (0V) and a “ring” (-48VDC). Phones and modems typically use the center pair of the connector (pins 4,5 in an 8 position (RJ45) jack or pins 3, 4 in a 6 position jack). 1) Connect the tone generator to the wall outlet using the RJ11 or RJ45 plug. 2) If the LED lights, a connection could exist. A negative polarity is normal for pins 4 and 5 (polarity is a concern with some digital systems).

Continuity test

The CTX590 Toner/Probe is a high quality wire locating tool that uses an induc-

e probe to sense a tone placed on the wires by its associated tone generator.

tiv 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.

● 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.

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.

TONE MODE

(set power switch to TONE)

TONE: Send tone

When in Tone Mode, the ProTone

sends a tone to a pair of conductors.

You detect the tone using the Probe

How to locate wires with the CTX590

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

Note: The tone generator can send a steady or an alternating tone. The selector

switch is inside the tone generator case.

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.

● Change the battery(s) when you suspect a weaker than normal tone.

TONE MODE

(using the probe)

The ProTone ﬁ ltered probe detects

the tone from the Tone Generator

Ultrabright LED shines from the tip of the probe

Volume control is on the back of the probe

Activates the probe's circuitry and ultrabright LED on the tip.

The "tone" LED is a visual indication that the tone generator's tone is detected.

"60HZ" LED warns that 60HZ (AC voltage) is present and should be av

oided

9V batter

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.
