4. Search of cables in the mode «Route»
The Route mode is the main mode for route location of various communications (cables, pipelines)
at all frequencies supported by the receiver, both a «passive» cable route location, and at the «active»
(with the use of the route locating generator). In the passive mode the cable location is carried out at
frequencies
50(60)100(120)Hz
, in the
active mode -512,1024, 8192, 32768 Hz
.
4.1. Cable location in the passive mode
This mode is used to search and locate a route of power cables under voltage with the frequency
50(60) Hz and other communications with the induced signal in frequency 50(60) Hz. The filter set
on the receiver - 50(60) Hz. The external generator is not used.
2. If the communication is far from the operator, you will see on the screen:
3. When moving towards the supposed place of the communication location, the «ball» will
appear on the screen. It shows the presence of communication, and that it is on the significant
distance from the operator.
4. The «ball» position shows, in which direction from the operator the communication is located.
4.2 Search of a communication and measurement of its burial depth.
1. Come to the supposed place of the communication under the voltage or induced voltage in
frequency 50(60) Hz.
