8. Performing a Cable Location in the Mode “MIN & MAX”
In.the.mode
“MIN & MAX”
,.the.device.works.simultaneously.both.on.the.method.“maximum”..and.
the.method.“minimum”..This.mode.is.used.in.the.conditions.of.distorted.field,.in.the.presence..of..nearby..
utilities.and.at..the.low..induced.signal..It..allows.the.user.to..perform..location.and.to..determine.the.
presence.and.location.of.utilities.located.nearby..
In.the
“MIN & MAX”
mode,.the.receiver.display.is.divided.in.two.halves..The.moving.diagram..of..the..
signal..level..change..is..displayed..in..the..upper..part..by..the.
“minimum”
.method..-..when..located.
over.the.cable,.the.signal.is.minimal,.and.when.deviating.from.the.axis,.the.signal.increases..The.bottom.
half.of.the.screen.shows.the.moving.diagram.of.the.signal.level.change.depending.on.the.time.by.the..
“maximum”..method..-..when..you..stand..over..the..cable,..the..signal..is..maximum,.and.when..deviating.
from.the.axis,.the.signal.decreases.
In.this.mode,.the.value.of.the.depth.and.current.in.the.utility.are.not.displayed..
The.signal.level.change..
diagram..At.each.updating.
of.the.display,.the.graphic.
automatically.shifts.by.one..
position.to.the.left,.and.the..
end.right.position.is.filled.with..
the.new.value
Digit.indicating.the.current..

The.cable.route.location.is.performed.similarly.to.route.location.in.the.“Graph”.mode,.orienting.
on.the.maximum.level.of.the.signal.on.the.lower.scale.of.the.graphic.and.the.minimum.level..of.the.
signal.on.the.upper.scale..To.determine.the.number.of.the.nearby.utilities,.you..should.step.aside.
from.the.axis.of.the.located.cable.and.go.straight.across.to.the.utility.axis.to.visualise.the.amount.
and.place.of.the.route.of.utilities..
