If the unit is lifted away from the wall dur-

ing a measurement, the last measured re-

sults remain in the display. If the unit is

placed against the wall again, the meas-

urement starts anew.

Examples of Measured Results (see fold-out page)

An object runs vertically in the wall

With several horizontal measuring passes one under the other, an ob-

ject 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 indication results.

An object runs horizontally in the wall

For horizontal passes in the examined area, no indication results. For

several vertical measuring passes side by side in the same area, an ob-

ject is indicated in each case. The marking of the object are next to

each other.

Point-shaped object (e.g. screw)

For several horizontal and vertical measuring passes over the same ar-

ea, an object is indicated only at a single location in each direction. The

markings of the object cross each other at the same location.

On the basis of the measured results, several objects occurring at reg-

ular intervals (e.g. reinforcing iron, hollow space in blocks) can be dis-

tinguished from individual objects (e.g. mains wiring). For this purpose,

make passes over a large measurement area and compare the results.

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.

Localisation of Objects

To localise an object, move the unit in direction of travel towards the ob-

ject 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 mid-

dle 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).
