5. Search of Utilities in “Route” mode

Route. mode. is. the. main. mode. for. route. location. of. various. utilities. (cables. &. pipelines). at. all.

supported.frequencies,.both.in.“passive”.cable.route.location.and.at.the.“active”.(with.the.use..of..
the..route..locating..generator)...In..passive..mode,.the..cable..location..is..carried..out..at..frequencies.
of.50(60).and.100Hz,.while.cable.location.in.active.mode.is.performed.at.frequencies.of.-512,.1024,.
8192.and.33Hz..

5.1  Cable Location in Passive Mode                    

.This.mode.is.used.to.search.and.locate.the.route.of.power.cables.under.voltage.with.a.frequency.

of. 50(60). Hz. and. other. communications. with. the. induced. signal. in. frequency. 50(60). Hz.. . The.
