10. Searching for a Pipe
To select the “Searching for a Pipe” measuring mode, perform the same steps as described in chapter
7.2.
Searching for a pipe can be carried out only in combination with the optional FAST-PWG (pulse wave generator)
(see Accessories (19)). The PWG is mounted to the pipe and in direct contact with the pressurized liquid
(hydrants, boreholes, ventilations, etc.). The PWG generates a periodic pressure wave which can be acoustically
received through the pipe.
The pipe amplifies the volume and the frequency of the impulse generated by the PWG most.

10.1 Setting the Volume, the Sensitivity, and the Frequency
To set the volume, the sensitivity, and the frequency, please perform the same steps as described in chapter 7.1.
To set the
frequency
manually, navigate to the symbol for setting the measuring frequency (1) on the display. In
order to set the frequency, use the dial on the right or a finger on the touch screen. The frequency window (2) will
open, setting the frequency is carried out as described in chapter 7.4.
