    HT-5000 4.2.2 Options for direct and inductive signal coupling CAUTION If the transmitter is connected to electrical service cables, it has to be considered that the device is designed to achieve CAT II / CAT III 440 V and CAT IV 300 V with Class 2 protection (double insulation) according to IEC / EN 61010-1.
  • Page 10 HT-5000 Application Principle of coupling Single-wire lines or pipes (with or without insulation against earthing) The distance between the earth spike and the ends of the connected lines should be as great as possible There is a danger of the return...

  • Page 11: Coupling With Special Accessories

    HT-5000 4.2.2.2 Coupling with special accessories The signal from the transmitter can be directly coupled into plug sockets, antenna connections coax and telephone jacks with the aid of a suitable adapter cable (Cod. 890008852). In doing so, it is not necessary to disconnect the lines.

  • Page 12: Inductive Signal Coupling

    HT-5000 4.2.2.3 Inductive signal coupling For lines which are not easily accessible, the signal from the transmitter has to be inductively coupled via the integrated antenna. The inductive coupling of the signal is highly recommended if unknown lines are to be located (e.g. at a construction site).
  • Page 13 HT-5000 Under certain circumstances lines at lower depths can 'hide' deeper, adjacent lines, thus making it more difficult to locate them. In such cases, the transmission characteristics of the transmitter TX5000 can be fully utilised and the lines which have already been located can be masked out (see Fig. 8) Fig.

  • Page 14: Signal Coupling In Non-Metallic Pipes

    HT-5000 4.2.2.4 Signal coupling in non-metallic pipes With the aid of the FlexSonde GOK50-R the transmitter's signal can be transmitted through non-metallic pipes, as shown in the picture below: Fig. 9: Signal coupling in non-metallic pipes Alternatively, any other active probe (e.g. a camera probe) with adequate transmitting frequency can be located using the receiver.

  • Page 21: Determining The Direction Of A Line

    HT-5000 4.3.3 Determining the direction of a line Step Action If the direction of the conductor will be determined with the aid of the TX5000 transmitter, couple the transmitter's signal onto the metallic conductor in such a way that there is as little signal loss as possible (see paragraph 4.2.2 and paragraph 4.3.1)

  • Page 22: Determining The Depth Of A Line

    HT-5000 4.3.4 Determining the depth of a line The RX5000 receiver has an automatic push key depth measurement feature. One precondition is that a clear signal from the TX5000 transmitter is coupled onto the conductor to be measured. For this procedure, the transmitter's signal has to be continuous (not pulsed) (see paragraph 4.2.1).
  • Page 23 HT-5000 With a steady grip, hold the receiver perpendicular to the position of a known metallic conductor, e.g. above a location which was marked during the site survey. The signal strength bargraph should show zero (see paragraph 4.3.2). In doing so, the tip of the receiver should...
