CONTINUITY MODE RED/GREEN LED CHART (set power switch to CONTINUITY) Voltage, polarity and continuity tests: The Red/Green LED is active in all three TM switch positions. See the following chart for the LED s meaning: The Red/Green LED indicates voltage, polarity and continuity WIRE LOCATOR ALL WIRE TYPES Switch position CONT: Test wire pair for continuity MODEL CTX590 LED color Tone Off Continuity Red Positive voltage Positive voltage Yes RED/GREEN Use this mode to detect whether LED Green Negative voltage Negative voltage NA a pair of wires has continuity. Alternating AC voltage AC voltage NA This test does not require the use of the probe. 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 test for continuity using the CTX590 How to determine polarity: Positive voltage on the red clip in relation to black clip is 1. Pick the pair of wires you wish to test for continuity. positive polarity as is pin 3 in relation to 4 (RJ11) and pin 4 in relation to 5 (RJ45). 2. Place the switch in the CONTINUITY position. When checking telephone polarity, a green LED is correct telephone polarity and 3.Attach the tone to the wires using either the RJ11, RJ45 or the alligator clips. a red LED is reversed polarity. 4.If the Red/Green LED lights, continuity exists on the pair. Detect telephone and modem connections using the Red/Green LED Note: You can verify whether you are in CONTINUITY mode by touching the Phone pairs have a tip (0V) and a ring (-48VDC). Phones and modems typically alligator clips together. Remember, if continuity exists across two conductors use the center pair of the connector (pins 4,5 in an 8 position (RJ45) jack or pins purposely, it is calledbridgin. If it is not by design, it is called ashor circuit. 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).
