5.12 Detecting the direction of water and heating pipes already installed (Single-pole
method)
When detecting the direction of water and heating pipes already installed, the respective water and heating
pipes must be suitably earthed connect the transmitter, as shown in figure 12.
Figure 12:
NOTE : Switching sensitivity between Level 1 and Level 3 increases the sensitivity by a factor of 5.
Setup: manual mode, minimal sensitivity. Maximum tracing depth 2.5 m.
5.13 Locating a complete house wiring (Single-pole method)
This method allows all circuits within an installation to be traced:
1. Turn off and isolate the supply in accordance with local regulations.
2. If applicable, remove the PE - N bridge within the distribution board.
3. Connect the transmitter “red” terminal to the Neutral bar and the “black” terminal to the Main
Earthing Terminal (figure 13). This will allow the neutral conductor of all circuits to be traced.
WARNING : For safety reasons the circuit must be switched off and isolated as per local
regulations.
