5.1.7  Finding metallic tap water- and heating pipe 
ATTENTION: 

The pipeline must be made of metallic materials (for example, piping made of galvanized steel). 

The pipeline must not be grounded. There should be a relatively high resistance between pipe 
and floor (otherwise the search distance is very small). 

Use a connection cable to connect the grounding socket on the transmitter with the ground and 
ground the end of the grounding cable properly. 

Use a connection lead to connect the socket "+" on the transmitter to the pipeline. 

 
The tracing of the installed tap water pipe and the heating pipe is shown in the following figures 
 

 

 

The end of the grounding cable of the transmitter should be located at a certain distance to the 
tracked pipeline. If the distance is too short, the signals and the circuit cannot be accurately 
located. 
 

The stronger the signals are displayed on the display of the locator during the tracking of the 
pipeline, the closer the tracked pipeline is to the locator. 
 

Set the transmission power in order to adapt it to different search radii. 
 

The target position can be located accurately by using the manual mode and adjusting the 
sensitivity.
