Above the center of an object, the measuring
indicator will exhibit maximum deflection, and
with sufficient signal strength, a center cross is
displayed. The color coding for the material
property is identical to that in the <Object
View>.
If the orientation arrows or the center cross are
not displayed, an object may nevertheless be
located in the immediate vicinity.
<Object View>
The <Object View> offers the best possible
measuring results and the maximum measuring
depths. The detected objects are displayed over
the measuring path with depth information and,
if available, with material properties.
Measuring process:
– Place the detection tool on the substrate and
move it over the substrate in the direction of
travel. The measuring results are shown on the
display after a minimum measuring path of
approx. 4 in (10 cm).
– Always move the detection tool in a straight
line while applying light pressure over the
substrate so that the wheels remain in contact
with the wall.
– To obtain optimum measuring results, move
the detection tool slowly over the entire area
to be checked and observe the measuring
results as you move the tool back. The
measuring path should be at least 15.75 in (40
cm).
– You can start a new measurement at any time
by pressing the red start button (16).
– If you lift the detection tool away from the wall
during the measuring process, the last
measuring result obtained remains on the
display. The measurement is restarted when
the device is set down or moved.
Operating Instructions
The tool's function allows for reliable detection
of the nearest edges of objects that run
transverse to the direction of movement of the
detection tool (see figure B). For this reason,
always move crosswise over the area to be
checked.
To locate objects, moving the detection tool
once over the measuring path is sufficient.
To identify the exact location of a detected
object and to mark the object, move the
detection tool back over the measuring path.
The direction of a found object in a wall can be
determined by moving along several offset-
measuring paths one after another.
Measuring indicator:
If no object was detected in the sensor range,
the dashed lines and the center line are
completely green.
If an object was detected under the sensor, it
will appear in the sensor range between the two
dashed lines of the display. The two dashed lines
and the center line are at least partially red.
In the right-hand depth scale, depending on the
setting, the object depth to the nearest edge of
the found object or the maximum permissible
drilling depth is displayed. You can change
between the two depths in the main menu.
Always use the display of the maximum
permissible drilling depth when using the
detection tool for the corresponding application.
The representation of the properties of detected
objects in the display can deviate from the actual
object properties. In particular, very thin objects
appear thicker on the display.
Larger, cylindrical objects (e.g. plastic pipes or
water pipes) may appear narrower on the
display than they actually are.
Depending on type and depth of the object,
identification of the material is possible. The
type of material can be recognized by the color
of the object in the display:
Yellow:
Blue:
Turquoise:
White:
Grey:
-17-
Live object
Magnetic metal (e.g. reinforcing steel)
Non-magnetic metal (e.g. copper pipe)
Non-metal material (e.g. wood, plastic)
Material property unknown
