4.3 Route location methods
1.The Maximum method
This method consists of positioning the electromagnetic sensor in the direction of the magnetic
field created by the utility radiation (fig.4.3). EMD antenna must be positioned horizontally and
the sensor placed in a plane perpendicular to the cable route. In this case the maximum signal
level is observed when the sensor antenna
passes directly above the utility line. The
maximum method is intended for a quick
route location. Flat peaks of the signal
level curve do not allow for high location
accuracy, but enables a quick route
location.
2. The Minimum method
When the EMD antenna in a vertical (transport) position is placed directly above the route
the signal is at its lowest level fig. 4.4. As the distance from the point directly above the pipeline
increases, the signal level first rises sharply then slowly decreases. This is the minimum method,
which is used to determine a more precise
route location (after quick route tracing
using maximum method.

5. Additional features
5.1 Task: Indirect electromagnetic mode of depth
measuring
Equipment used: receiver AP-027, electromagnetic
sensor EMD
Tip: When determining the depth, one should take into
account the terrain. In order to obtain precise results, select
flat surface areas.
Method: 1. Find the precise pipeline route location
(preferably using the minimum method). Mark the spot.
2. Fix the sensor antenna at a 45 angle to the ground surface,
minimum of the signal is observed at a distance from the point
«above the route», equal to the depth of the utilities, when the
antenna axis intersects the axis of the route. This is the indirect
method of measuring the depth of utility (fig. 5.1)
5.2 Task: Detecting the pipeline and utility lines intersection point.
Equipment used: receiver AP-027, electromagnetic
sensor EMD, headphones.
Fig.5.1
Fig.5.2
Method: 1. Perform preliminary pipeline route location.
2. Turn on the receiver and set it up for broadband.
3. Рosition the electromagnetic antenna over the
pipeline, parallel to the pipeline route (signal level
displayed on the receiver screen will be close to zero)
(fig. 5.2). Perform route location in accordance with
the maximum method. When following the route, the
intersection points with utility lines can be identified by
the maximum signal.

9. Audio indication
The sound is output to the headphones or the built-in sound transmitter. Three categories of
sound are used:
- «Natural» without filtering (broadband) to the phones;
- «Natural» filtered (narrowband) to the phones;
- «Synthetic» (modulation of sound frequency by the level of the filtered signal) to the phones
or to the built-in transmitter.
When working with AD only «natural» sound is used.
When working with EMD in the mode «natural sound to the phones» the adopted «high active»
frequency 8192Hz and 33kHz, before playing, are converted into a well-acceptable «low»
frequencies of 1575 Hz and 3470 Hz respectively.
«Synthesized» sound is created by a principle: «Frequency of the audible sound signal (pitch)
is directly proportional to the signal level,» and the volume does not depend on the level of the
received signal. «Synthesized» sound is played while values «figure≥2».
The volume of the headphones is set by the operator using buttons ◄/►. Two pressings
correspond to the one change of figure on the display «8 ... 1/1…8».
Volume of the «synthesized» sound on the built-in transmitter can not be regulated.
