Wall Surface Measurement (see figure J)
The wall surface measurement is used to deter-
mine the sum of several individual surfaces with
a common height.
In the example shown, the total surface of sev-
eral walls that have the same room height A, but
different lengths B, are to be determined.
For wall surface measurements, press button 11
until the indicator for wall surface measurement
appears on the display.
Measure the room height A as for a length meas-
urement. The measured value is indicated both
at the top and bottom in the display. The laser
remains switched on.
bottom in the display, while the surface is indi-
cated at the top. The laser remains switched on.
both lengths is multiplied with the stored length
A. The total surface value is indicated at the top
in the display.
In this manner, you can measure any number of
further lengths B
, which are automatically add-
X
ed and multiplied with height A.
The condition for a correct area/surface calcula-
tion is that the first measured length (in the ex-
ample the room height A) is identical for all par-
tial surfaces.
To restart the wall surface measurement, press
button 11 twice.

Deleting Measured Values
Briefly pressing button 14 deletes the last indi-
vidual measuring value determined in all meas-
uring functions. Briefly pressing the button re-
peatedly deletes the individual measured values
in reverse order.
In the wall surface measurement mode, briefly
pressing button 14 the first time deletes the last
individually measured value; pressing the button
a second time deletes all lengths B
Memory Functions
When switching off the measuring tool, the val-
ue in the memory is retained.
In the wall surface measurement mode, the total
surface value can be stored; in the minimum and
maximum measuring mode, the minimum and
maximum value can be stored correspondingly.
Storing individual measuring values within these
functions is not possible.
Storing/Adding Measured Values
of
2
soon as a value has been stored, "M" is indicat-
ed in the display and the "+" behind it briefly
flashes.
If a value is already stored in the memory, the new
value is added to the memory contents, however,
only when the measures of unit correspond.
As an example, when an area value is in the
memory and the current measured value is a vol-
ume value, the addition cannot take place.
"Error" briefly flashes in the display.
Subtracting Measured Values
Push the memory subtraction button 12 in order
to subtract the current measured value from the
memory value. As soon as a value has been sub-
tracted, "M" is indicated in the display and the
"–" behind it briefly flashes.
If a value is already stored in the memory, the
new measured value can be subtracted only
when the measures of unit correspond (see
"Storing/Adding Measured Values").

current measured value – a
length, area or volume val-
ue, depending on the cur-
rent measuring function. As
