4.2.5 Determining the depth of a line (not available for
Easyloc
Basic
)
Preconditions for
automatic depth
measurement
The
Easyloc Rx
receiver has an
automatic
pushbutton depth measurement feature.
One precondition is that a clear signal from the
Easyloc Tx
transmitter is coupled onto
the conductor to be measured. For this procedure, the transmitter's signal has to be
continuous (not pulsed) (see section
4.1.1 Transmitter signals and modes of
In addition to this precondition,
automatic
depth measurement will only function when
the mode of operation of the receiver is set to
TRANSMITTER
. It will not function if
set to
POWER
GRID
or
RADIO
.
If these preconditions are not met, a
rough estimate
of the depth may be made using
the manual method.
Measuring depth with the
aid of a probe
If the depth of a non-metallic pipe needs to be determined, the measurement has to
be made with aid of a probe, e.g.
FlexSonde
(see section
). In order to accommodate the transmission characteristics of a
probe, the
Easyloc Rx
receiver has a special depth measurement mode which has to
be activated through the system settings (see section
As a result, the way a depth measurement can be performed depends not only on the
active operation mode but also on how the depth measurement mode is set
(Transmitter or Probe). A symbol in the lower left of the display indicates which mode
is currently accessible:

Description
For determining the depth of a probe which has been pushed into a
non-metallic pipe.
For determining the depth of a line, the signal of an active transmitter is
coupled onto.
For determining the depth of a line which carries radio signals or grid
frequency signals.
Even after the depth has been successfully determined, all excavation work should
be done with caution. This is particularly important if a
rough estimate
of the depth
was made, as this can result in even greater deviations.
