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 Localisation of
Objects).
The extent of the object found in the wall can be determined when several
offset measurement passes are made shifted with respect to each other
(see Examples of Measured Results
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.
