Examples of Measured Results (see fold-out page)
An object runs vertically in the wall
A
With several horizontal measuring passes one under the other, an object
is indicated in each case. The markings of the object are vertically one
below the other. For vertical measuring passes in the same area, no indi-
cation results.
An object runs horizontally in the wall
B
For horizontal passes in the examined area, no indication results. For sev-
eral vertical measuring passes side by side in the same area, an object is
indicated in each case. The marking of the object are next to each other.
Point-shaped object (e.g. screw)
C
For several horizontal and vertical measuring passes over the same area,
an object is indicated only at a single location in each direction. The mark-
ings of the object cross each other at the same location.
On the basis of the measured results, several objects occurring at regular
intervals (e.g. reinforcing iron, hollow space in blocks) can be distin-
guished from individual objects (e.g. mains wiring). For this purpose,
make passes over a large measurement area and compare the results.
Localisation of Objects
To localise an object, move the unit in direction of travel towards the object
until centre line h of the unit is exactly above centre i of the object found
on the display. The object in then located exactly under the middle of the
unit. With the help of the aligning aid 9, the position of the object can be
marked (Fig.
The marking can also be made with the aid of the outer edge of the unit
(Fig. , with reference to line g).

If the unit is lifted away from the wall during
a measurement, the last measured results
remain in the display. If the unit is placed
against the wall again, the measurement
starts anew.
zontally in the wall
Example: In the illustration, three evenly
spaced objects with an associated drilling
depth of 4 cm are recognisable that, as a
result of their position and depth, can be
assumed to be reinforcing iron. The fourth
object at 2 cm depth can be, for example,
a mains cable.
