This ensures automatically, that the user remains with the sensor directly on top of the cable, which makes the fault location more accurate but also easier. Weak fault are much faster detected and located. A cross measurement is not required, since the system is positioned automatically in theYaxis on top of the cable (c) SebaKMT , all rights reserved The Compass The ?Compass“ function of the digiPHONE+ recognises from the data, especially from the difference time measurement, if the user is moving towards the fault. This is indicated by the arrow in the display. The user follows the arrow and ppoaches automatically the fault position If the digiPHONE+ detects an increase of the difference time, it means, that the user has passed the fault already. In this case a bent arrow indicates this and requests the user to move backward. Before the fault: The new value is lower than the old difference value After the fault: The new value is higher than the old difference value (c) SebaKMT , all rights reserved MFM 10 (c) SebaKMT , all rights reserved (c) SebaKMT , all rights reserved 41 Example from Greece 42 Bad workmanship as standard problem More and more units are installed by unexperienced cheap service panies worldwide. ?
