Measuring Procedure - Bosch D-TECT 100 Operating Instructions Manual

Measuring Procedure

The unit does not display the wall as transparent but rather in
cross section.
Move the unit in the direction of travel (see Functional Method) over the
wall. Measured results are shown on display 3 after a few centimeters.
To ensure correct measurement results, the unit must be moved over
a distance of at least 8 cm.
During the measurement, the following display elements appear:
l
Display Elements
a Measurement display type
b Cross section of the unit
c Wall surface
d Depth scale for allowable drilling depth
e Dimensional unit for the depth scale
f Grey: Area not yet examined
g Outer edges of the unit
h Middle line of the unit whose position corresponds to the aligning
aid 9 on the unit
i Centre of object found in the wall
k Black: Object found in the wall
l White: Already examined area
If an object is found in the wall, a black mark k appears in the white
area l. The depth to which drilling can take place is readable on the
depth scale d in the display.
Example: In the display above, an object is located on the left next to
the unit. At this position, drilling to a depth of 4 cm can be performed.
To detect objects, one pass over the measured surface is adequate.
If no object was found, repeat the movement over the wall transversely
to the original measurement direction (see Functional Method).
To exactly localise and mark an object found, move the unit back over
the measured surface without lifting it from the wall (see also Localisa-
tion of Objects).
The extent of the object found in the wall can be determined when sev-
eral offset measurement passes are made shifted with respect to each
other (see Example for Measurement Results
pose, mark and connect the respective measured points.
By pressing the "start" button 6, the display of the objects found can
be deleted at any time and a new measurement started.

If the unit was not switched on while being
held against the wall, a prompt appears in
the display to place the unit against the
wall for measuring.
