List of the last Measuring Values
The measuring tool stores the last 20 measuring values and
their calculations, and displays them in reverse order (last
measured value first).
To recall the stored measurements, press
button 7. The result of the last measure-
ment is indicated on the display, along
with the indicator for the measured-value
list e and the memory location of the dis-
played measurements.
When no further measurements are stored after pressing but-
ton 7 again, the measuring tool switches back to the last
measuring function. To exit the measured-value list, press
one of the measuring-mode buttons.
To continuously save the currently displayed length measure-
ment value as a constant, press and hold the measured-value
list button 7 until "CST" is indicated on the display. A meas-
ured-value list entry cannot be subsequently saved as a con-
stant.
To use a length measurement value in a measuring mode (e. g.
area/surface measurement), press the measured-value list
button 7, select the desired entry and confirm by pressing the
result button 6.
Deleting Measured Values
Briefly pressing button 8 deletes the last individual measuring
value determined in all measuring functions. Briefly pressing
the button repeatedly deletes the individual measured values
in reverse order.
To delete the currently displayed measured-value list entry,
briefly press button 8. To delete the complete measured-val-
ue list and the constant "CST", press and hold the measured-
value list button 7 and at the same time briefly press button 8.
In wall surface measurement mode, briefly pressing button 8
the first time deletes the last individually measured value;
pressing the button a second time deletes all lengths B
pressing the button a third time deletes all room heights A.
Adding Measured Values
To add measured values, firstly carry out any measurement or
select an entry from the measured-value list. Then press the
plus button 11. For confirmation, "+" appears on the display.
Then carry out a second measurement or select another entry
from the measured-value list.
To call up the sum of both measurements,
press the result button 6. The calculation
is indicated in the measured-value lines a,
and the sum in the result line c.
After calculation of the sum, further
measured values or measured-value list
entries can be added to this result when pressing the plus but-
ton 11 prior to each measurement. Pressing the result button
6 ends the addition.
Notes on the addition:
– Mixed length, area and volume values cannot be added to-
gether. For example, when a length and area value are add-
ed, "ERROR" briefly appears on the display after pressing
Bosch Power Tools
the result button 6. Afterwards, the measuring tool switch-
es back to the last active measuring mode.
– For each calculation, the result of one measurement is
added (e.g. the volume value); for continuous measure-
ments, this would be the displayed measured value in re-
sult line c. The addition of individual measured values from
the measured-value lines a is not possible.
Subtracting Measured Values
To subtract measuring values, press mi-
nus button 5; For confirmation, "–" is in-
dicated on the display. The further proce-
dure is analog to "Adding Measured
Values".
Working Advice
General Information
The reception lens 17 and the laser beam outlet 16 must not
be covered when taking a measurement.
The measuring tool must not be moved while taking a meas-
urement (with the exception of the continuous measurement
and grade measurement functions). Therefore, place the
measuring tool, as far as this is possible, against or on a firm
stop or supporting surface.
Influence Effects on the Measuring Range
The measuring range depends upon the light conditions and
the reflection properties of the target surface. For improved
visibility of the laser beam when working outdoors and when
the sunlight is intense, use the laser viewing glasses 27 (ac-
cessory) and the laser target plate 28 (accessory), or shade
off the target surface.
Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot be ex-
cluded when measuring on different surfaces. Included here
are:
, and
X
– Transparent surfaces (e.g., glass, water),
– Reflecting surfaces (e.g., polished metal, glass),
– Porous surfaces (e.g. insulation materials),
– Structured surfaces (e.g., roughcast, natural stone).
If required, use the laser target plate 28 (accessory) on these
surfaces.
Furthermore, faulty measurements are also possible when
sighting inclined target surfaces.
Also, air layers with varying temperatures or indirectly re-
ceived reflections can affect the measured value.
Accuracy Check and Calibration of the Grade Measure-
ment (see figure H)
Regularly check the accuracy of the grade measurement. This
is done by carrying out a reversal measurement. For this,
place the measuring tool on a table and measure the grade.
Turn the measuring tool by 180 ° and measure the grade
again. The difference of the indicated reading may not exceed
by more than 0.3 ° (max.).
