Bosch Power Tools

After taking the third measure-

ment, the volume is automatically 

calculated and displayed. The last 

individual measured value is indi-

cated at the bottom in the display, 

while the final result is shown at 

the top.

Continuous Measurement (Tracking) (see figure D)

For continuous measurements, the measuring tool can be 

moved relative to the target, whereby the measuring value is 

updated approx. every 0.5 seconds. In this manner, as an ex-

ample, you can move a certain distance away from a wall, 

while the actual distance can always be read.
For continuous measurements, first select the length measur-

ing function and then press button 

9

 until the indicator for 

continuous measurement

 appears on the display. The la-

ser is switched on and the measurement starts immediately.

Move the measuring tool until the 

required distance value is indicat-

ed in the bottom of the display.
Briefly pressing button 

9

 ends the 

continuous measurement. The last 

measured value is indicated at the 

bottom in the display. Pressing button 

9

 for several seconds 

restarts a continuous measuring run.
Continuous measurement automatically switches off after 

5 min. The last measured value remains indicated at the bot-

tom on the display.

Deleting Measured Values

Briefly pressing button 

13

 deletes the last individual measur-

ing value determined in all measuring functions. Briefly press-

ing the button repeatedly deletes the individual measured val-

ues in reverse order.

Memory Functions

When switching off the measuring tool, the value in the mem-

ory is retained.

Storing/Adding Measured Values

Push the memory add button 

3

 in 

order to store the current meas-

ured value – a length, area or vol-

ume value, depending on the cur-

rent measuring function. As soon 

as a value has been stored, 

“M”

 is 

indicated 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 volume value, the addition cannot 

take place. 

“Error”

 briefly flashes in the display.

Subtracting Measured Values

Push the memory subtraction button 

11

 in order to subtract 

the current measured value from the memory value. As soon 

as a value has been subtracted, 

“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 corre-

spond (see “Storing/Adding Measured Values”).

Displaying the Stored Value

Push the memory retrieve button 

2

in order to display the value stored 

in the memory. 

“M=”

 is indicated 

in the display. When the memory 

contents 

“M=”

 is indicated in the 

display, it can be doubled by push-

ing the memory add button 

3

 or set 

to zero by pushing the memory 

subtract button 

11

.

Deleting the Memory

To delete the memory contents, first push the memory re-

trieve button 

2

, so that 

“M =”

 is indicated in the display. Then 

briefly press button 

13

; 

“M”

 is no longer indicated in the dis-

play.

Working Advice

General Information

The reception lens 

19

 and the laser beam outlet 

18

 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 

function). Therefore, place the measuring tool, as far as this is 

possible, against or on the measuring points.
Measurement takes place at the centre of the laser beam, 

even when target surfaces are sighted at an incline.

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 

21

 (ac-

cessory) and the laser target plate 

22

 (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:
– 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 

22

 (accessory) on these 

surfaces.
Also, air layers with varying temperatures or indirectly re-

ceived reflections can affect the measured value.
