1. TC TP1 Net Probe Amplified Inductor and Tone Probe Never connect this Probe to a live wire from a non compatible telephone network system Doing so may damage the Probe and or the equipment Please observe and follow all safety protocols to avoid injuries A Description The Net Probe is a feature packed tone tracer It is ergonomically designed to fit in the hand of the operator The Probe can also accept a 2 5mm earphone to help the operator listening to the tone in a noisy environment When combined with a compatible cable tester with built in tone generator you can trace and test a cable swiftly The Net Probe has a RJ 45 connector you can use it to quickly detect voltage on the center pair or exam telephone line s polarity On the back of the Net Probe there are two test pins for clip leads to quickly access RJ 45 jack s middle pins Pin 4 and 5 The tip on the Net Probe is also replaceable and the lanyard provides quick access to the Probe The Net Probe is compatible with most Tone Generators on the market making it one of the best investments in your toolbox B Tone Tracing Instruction To use the Net Probe you must first install a compatible Tone Generator Tester Connect the Tone Generator to the test cable please refer to the manufacturer s manual If the use of a 2 5mm earphone is preferred connect a compatible earphone to the Probe s Earphone Jack and set audio output selector from speaker to earphone The Net P2. erify the phone number If one or both NORM and REV LEDs are on electric current is present on the center pair of the jack wire 4 and 5 on RJ 45 or wire 3 and 4 on RuJ 11 and RJ 12 If none of the LEDs lights the cable is most likely not connected ii Checking low voltage for AC or DC less than 24 volts Ifthe REV LED lights solid yellow the test lead is connected to the negative DC pole and the lead is connect to the DC pole Ifthe NORM LED lights solid green the test lead is connected to the negative DC pole and the lead is connected to the DC pole Tip Replacement 1 To replace Probe tip grab the tip with your fingers and twist it counter clockwise until the tip comes off 2 Replace old tip with a compatible new tip included and twist the tip clockwise until snug Do not over tighten the tip Low battery indicator When the battery power is low the LOW BATT LED will light red Replace the old battery with a fresh one Battery Replacement 1 The Net Probe requires one standard Alkaline DC 9 volts or compatible battery 2 Slide back the battery cover to replace the old battery with new one S112102
3. medium low level Begin tracing the cable starting from the tone generator Continue tracing along the cable and when the tone disappear the location of the Probe is where the cable break Adjust the gain control to high level to pinpoint isolate the location of the break Note The tone is at its loudest when the tip of the probe is near and parallel to the cable carrying the tone signal C Line Testing Instruction Use this function on the compatible Analoque telecom and network system only 1 Set the TEL TRACE selector to es TEL position 2 Connect the RJ 45 modular jack on the Net Probe to a wall jack using the jumper cable 3 Check the LED indicators under TEL i Identifying telephone line polarity and verifying telephone line s function NORM This LED lights green when the analog telephone patch cable or the outlet is installed properly It indicates the telephone line carries proper voltage and has correct polarity REV This LED lights yellow when the analog telephone patch cable or the outlet is wired incorrectly It indicates the telephone line s polarity is reversed If both NORM and REV LEDs are on the line carries AC current abnormal Disconnect from the line and proceed with caution If one of the LEDs is on solid this indicates the presence of DC current If both NORM and REV LEDs are flashing the line is ringing You can use this feature to v
4. robe is also equipped with a LED Signal indicator to provide a visual feedback when detecting tone 1 Locate the battery compartment on the back of the Probe 2 Push the triangle marking on the cover and push it away from the Probe The cover should slide away to reveal the battery compartment 3 Connect a fresh 9V DC battery t the connector and slide the cover back to close the compartment 4 Set the TEL TRACE selector on the left hand side of the Probe to TRACE position 5 Point the tip of the Probe to the cables that you are testing and push and hold the TRACE button to trace a line 6 You can also connect a RJ 11 or RJ 45 jumper cable from the Probe s RJ 45 jack to a wall jack to test its polarity i Tracing for unknown cable path termination Adjust gain volume control to the desired level and begin tracing from the tone generator location Adjust the volume gain control to maintain a constant tone Trace over the entire path of the test cable or until the cable end is located ii Locating termination verification general area of termination Adjust gain volume control to the maximum level Begin tracing in the general area of the cable termination Zigzag the Probe slowly and exam the entire area Avoid any high voltage sources and adjust the gain control when necessary to maintain a constant tone iii Locating conductor break discontinuity Adjust gain volume control to
