  • Page 4: Overview

    1. Overview 1.1. General information about cable tracing A cable tracer does not locate the actual cable, rather the magnetic or electric field, which exists in the cable by nature or has been induced to it using the transmitter. As the shape of the magnetic field depends on other wires and pipes that may be located near the target object, it is important for the user to be familiar with the properties of the device as well as possible.

    2.3. Receiver TMR30 Nose section with antennas : Nose has three integrated antennas: Capacitive antenna for Monitor modes and Open wires mode, close range antenna for Near cable mode and rod probe for Cable-route mode. Work light: The LED light under the nose turns on and off by briefly pressing Power button.

  • Page 8: Batteries And Warnings For Use

    3. Batteries and warnings for use 3.1 Batteries TMT30 transmitter uses 6 pcs. 1.5V LR20 (size AA, Mignon) alkaline batteries and TMR30 receiver 4 pcs. 1.5V LR03 (size AAA) alkaline batteries. Both have a battery compartment at the back of the device, under a lid with two screws. If a there is Battery Low message on TMT30 LCD or the active mode LED of TMR30 blinks, batteries are weak and should be replaced to ensure the optimal functioning of the equipment.

    5. Using the receiver General TMR30 starts when Power button is pressed until a beep sound is heard. Level bar will display battery level while start-up; the higher LED bar, the higher is battery voltage. If Power button is pressed briefly during use, the work light under the nose turns on and Level bar displays battery level just like during start-up.

  • Page 11: Adjusting Receiving Gain

    Adjusting receiving gain Receiving gain (sensitivity) can be adjusted with the 3-step GAIN adjustment and GAIN LEDs display which gain setting is on. It is recommendable to use gain, which makes the Level bar height to be approx. in the middle; that way changes in signal strength are easiest to notice.

  • Page 12: Near Cable Mode And Close Range Antenna

    6.2 Near cable mode and close range probe Near cable is a very versatile mode. It can be used to trace wires and cables up to 40cm distance and even inside structures or big bunch of wires or cables. Near cable mode works nicely when open (unconnected) cross connection wires need to be traced or when telecom pairs, electric wiring or antenna cables need to be located and traced.

  • Page 13: Cable Route Mode And Rod Antenna

    6.3 Cable route mode and rod probe Cable route mode is intended for tracing cables and tubes even underground. Also Cable route mode is based on inductive tracing in which a magnetic field created by a current running in a wire is detected with the TMR30 rod antenna.

  • Page 14: Practical Usage Examples

    7. Practical usage examples In this paragraph there are two symbols used to describe grounding & earth connection: This symbol means grounding through constructions, such as grounded pipes, metal chassis, mains wall socket protective earth connector etc. This symbol means direct earthing to soil with a ground pick or other similar means so that no other constructions are involved.

  • Page 15: Tracing Underground Cables And Routes

    7.1.2 Tracing wires pairs at cable ends or joints Task: A pair needs to be recognized at the end of an open cable or joint. Connect transmitter to the traced pair. Choose Open wires mode with receiver and move receiver nose close to the exposed wires.
  • Page 16 7.2.2 Live mains cables Task: The route of a live electric cable must be traced above ground. Connect one transmitter output terminal to the protective earth wire of the cable or e.g. to a wall socket PE contact. If the task is to trace the feeder cable of a metallic light pole, transmitter can be connected to the earthed pole itself.

  • Page 17: Tracing Cables And Wires Indoors

    7.3 Tracing cables and wires indoors 7.3.1 Live and neutral electric cables To connect transmitter to live targets, always use proper contact proof safety class cords and adapters and follow safety instructions. WARNING! If either transmitter output terminal is connected to a live target as shown in the figure, dangerous voltage appears on wires connected to the other output as well, unless they are properly grounded.
  • Page 18 7.3.2 Wall sockets and circuit breakers & fuses Task: Electronic circuit breaker for a certain live wall socket needs to be located at the electrical panel or cabinet. Connect transmitter to the Schuko wall socket between phase (P) and either neutral (N) or protective earth (PE) contacts with the S3TB cord respective wires.

  • Page 19: Tracing Special Cables

    7.3.3 Electric cables which can’t be galvanically connected Task: The route and end of a cable from a cabinet needs to be located without disconnecting the cable or opening the cabinet. Connect transmitter with a clamp-on transformer (PM50 or PM100) to the cable at a place where the cable is visible.

  • Page 20: Floor Heating Cables And Their Faults

    7.4.2 Generic cabling systems (data cables and RJ45 sockets) Task: Route of one generic cabling system cable needs to be traced. Connect one transmitter output terminal to one wire or pair of the traced cable RJ45-socket. Connect transmitter second output terminal to grounding such as the protective earth (PE) contact of a wall socket.
  • Page 21 7.5.2 Preliminary inspection of the target area As a first step it is always recommendable to perform a systematic inspection at the cable assembly area, assembly method as well as fault type. When and how the fault appeared Did it blow a fuse (short circuit) Did the cable just stop heating (cut cable) Did a residual current device trip (ground leak) Have there been renovation or other changes going on at the target area, such...
  • Page 22 Near cable method Connect transmitter between the cable’s phase (L) and neutral (N) wires. Choose Near cable mode with receiver. Use the receiver in upright position or upside down as in the figure, so that either nose groove spot is close to the floor. Trace the cable route by following the signal minimum.

  • Page 23: Tracing Cable Faults

    Task: An open in a floor heating cable needs to be traced. Several factors affect tracing an open in a heating cable, such as what cable type is at hand, is the cable fully cut or just one wire and what kind of grounding there is to concrete reinforcement.

  • Page 24: Tracing Tubes And Ducts

    7.6.2 Location of a open wire (cut fault) Task: Cable has a open (cut fault) which location needs to be traced Connect one transmitter output terminal to the open wire. Connect second output parallel to the remaining wires (e.g. with mains cable) and possible shielding and all of them finally to a good grounding, preferably using a ground pick to ensure best earth connection.

    7.7.2 Non-conductive pipes inside walls etc. Task: The route of a non-conductive tube or possible tube blockage needs to be traced inside wall. Use the 10m long SPA10 pipe transmitter antenna accessory, which is inserted into the tube such as an electrical pipe. If there is a blockage in a tube which needs to be located, connect both SPA10 terminals to the transmitter and push the antenna into the tube until it hits the blockage.

    7.8.2 Audio freq mode Task: Monitor audio frequencies of various objects. Use Audio freq mode to monitor audio frequencies up to 10kHz without galvanic contact to the object, e.g. to wires. The monitored audio signal level must be relatively high and receiver nose must be taken as close to the target object as possible.
