2.2 Electronic Unit
The newly developed GPA 1000 V16 impresses with a new design and an easy
handling.
S: Sensor value
C: Calibration value
Bat: battery charge condition (graphically and in percent)
The calibration is conducted by a microprocessor and carried out automatically on
every soil. Further modulations are not necessary. Therefore the GPA 1000 V16 set
is applicable on every soil type.
The measured data is automatically digitized and transformed to the tablet computer
via Bluetooth® wirelessly. The blue LED flashes after activation, constant light
indicates the Bluetooth® connection.

2.3 Start of electronic
The Bluetooth®-connection allows a fast and save transfer of measured data from
GPA 1000 V16 to the tablet computer –in contrast to other devices, which record
data via parallel interface.
Through the On-/Off-button the current battery charge condition can also be
controlled (graphically and in percent). At the same time the sensor and calibration
data is shown. The sensor data should always be between 2 to 3, the calibration data
approx. 2.5 (before the calibration automatically is set, display could temporarily
indicate other values).

3 Start of program
Boot up the PC and double-click on the KTS-3D icon, then start the KTS software.
GPA 1000 V16 automatically is connected to the computer (be sure that GPA 1000
V16 is activated before you start KTS 3D-Software). Should this not be the case, we
point to page 23, item 6.7.
3.1 GPA Visualizer
The current model of GPA 1000 V16 is additionally equipped with the new “GPA
Visualizer” 3D software.
The “GPA Visualizer” 3D software is an easier option for a fast scanning, because
the required input of track length or track number, values per track and moving
direction is no longer necessary.
In the lower right you see the blue-framed icon “GPA Visualizer”. A double click on it
will start the software.

KTS-Electronic GmbH & Co. KG - GPA 1000

The program only requires setting of measuring speed (normal, fast, max. speed)
before the measurement starts by pressing the start button.
By pressing the „Stop“ button it is possible to interrupt the search at anytime. With the
“Start” button the search is continued. Should the search be re-started, please press
the “Reset” button.
The search should always be proceeded in a straight line. With every change in
direction (also by turnarounds or bypassing of obstacles) an interruption of
measurement through “Stop” button is appropriate.
Press the “Start” button again to continue the search. Otherwise wrong values could
be indicated while change in direction.

KTS-Electronic GmbH & Co. KG - GPA 1000
11
At the beginning of the search it is necessary to adapt the running direction to a
sensor value of 2 to 3. Otherwise the higher search performance will quickly reach
the highest resp. lowest sensor value.
After conclusion of measurements it is possible to change the 2D model to a 3D
model by pressing the “3D” button.
The automatic data interrogation is carried out after storage and completion of the
measurement. Click “file” and ”save” if you want to save the data. Once these steps
are completed, the search can be continued from the point where it was interrupted.
3.2 Preadjustment KTS 3 D
With the "new" button on the display the setting window is opened and
the computer requires the input of track number, track length, values per track and
measurement speed, etc.

KTS-Electronic GmbH & Co. KG - GPA 1000
12
3.2.1 Start-button
By pressing the start button the search is initiated. On screen the results are
displayed 2-dimensional. After all values are determined, the program stops
automatically and the next track measurement can be carried out.
3.2.2 Completion of measurement
After completion of the last track, you are going to be asked, if you want to save the
measurements. With the O.K.-button the measurement is automatically stored in a
user-defined file.
3.2.3 Transfer of measurement data
The provided USB-stick can also be used for the transfer of measurement data; you
are able to transmit to other PCs and call up all informations for further processings.

KTS-Electronic GmbH & Co. KG - GPA 1000
13
3.2.4 3D presentation
The measurement data is shown in 3D.
The 3D presentation shows every modification and its dimension.
3.3 Search process (measurements)
The GPA is a measuring device, which can measure alterations of ground anomalies
(caused by metal objects, soil structure or excavations) and can discriminate from
normal ground magnetism. Correct results strongly depend on ground type and
measuring method. Areas to be measured should not have electric fields (like high
voltage cables or earth wires) or strong mineralising or wet grounds because they
influence the measurement. The dryer the soil, the more precise the results.
Split the area you want to measure into even tracks. You may choose between 2
methods:
3.3.1 Search in one direction

KTS-Electronic GmbH & Co. KG - GPA 1000
14
If you have chosen the search in rectification, you should come back to the starting
point after completion of each track and press the start button (for the measurements
of the second track).
3.3.2 Search in counter direction
If you have chosen the search in counter direction, you should turn around after
completion of each track, make a sidestep of approx. 50 cm (20 inches) to the right or
to the left and continue with the next track by pressing the start button.
For precise measurements the walking speed should be constant while pacing the
tracks. Hereby objects can be detected at the same spot during counter direction. For
exact measurements track lengths between 5 to 10 meters (16 to 32 ft.) are
expedient.

4.3.4 Serial Interface
In case of a reinstallation you can select the utilized Comport (see page 23, 6.7
Bluetooth pairing).
5 Data recordings
5.1 Modulation before data recording
Prior to data acquisition various settings are needed. In conjunction with the track
values the track length determines the distance between the single
measurements.(see step width/settings window KTS 3D). The values per track are
limited to a maximum of 100.

KTS-Electronic GmbH & Co. KG - GPA 1000
19
After pressing [Start] button the measurement is activated; this can be carried out
either manual or time-controlled (standard setting is 0.2 sec). With the [Cancel]
button a program termination is given at all times. The switch between consensual
and contrasensual movement is also possible.
5.1.1 Display during data recording
During data recording the display turns up two-dimensional and in color gradation. Of
course, the shown nuances are dependent on the selected modulation. The end of a
track is displayed, after confirmation the new track will be measured. A storage
request appears at the end of the last track; afterwards a switch to the three-
dimensional representation takes place.
5.1.2 Display after completion of data recording
Illustration results from under 5.1.1 pictured two-dimensional representation.

KTS-Electronic GmbH & Co. KG - GPA 1000

5.2 Display alternatives
5.2.1 Proportional or square display
With the button [prop.] the representation switches between proportional and
quadratic view. In the quadratic representation the image shows up with square
elements. Details partially are better recognized here. The relation between track
length to field width is not taken into account. The proportional representation is
displayed under consideration of the real track length and field width like it was setted
in [data recording].
Note:The actual measured length / width is only given through the setting [data
recording]. The correct input of exact length and width is essential.
5.2.2 Data presentation - absolute or relative
Here it is possible to switch between absolute or relative data presentation. The
absolute representation shows the entire measuring range on the Z-axis. The value
range for the relative representation is based on the smallest and largest measured
value. This results in a maximum detail resolution –also with regard to the color
representation.
6 Search process
During soil analysis you may choose between different search modes.
6.1 Search with the universal probe
Activation through ON-/OFF-button.
After switch-on display shows battery condition.
Wireless connection via Bluetooth from computer to electronic unit.
Hold the probe so that the arrow (fixed laterally) points to the ground during
search (this way you will attain the highest search performance).
Check of calibration (approx. 2.5) and
Control of sensor value.
Verify, that the indicated value is between 2 to 3. Should this not be the case,
change the search direction slightly so that above value is displayed.
The further search process is decribed under 6.3.
