a) Indirect height measurement (see figure C)

Press the function-mode button 4 until the indication 

for indirect height measurement 

 appears on the 

display.

Pay attention that the measuring tool is positioned at 

the same height as the bottom measuring point. Now, 

tilt the measuring tool around the reference plane and 

measure distance “1” as for a length measurement.

Upon completion of the measure-

ment, the result for the sought dis-

tance “X” is displayed in the result 

line c. The measuring values for the 

distance “1” and the angle “α” are 

displayed in the measured-value 

lines a.

b) Double indirect height measurement 

(see figure D)

Press the function-mode button 4 until the indication 

for double indirect height measurement 

 appears 

on the display.

Measure distances “1” and “2” in this sequence as 

for a length measurement.

Upon completion of the measure-

ment, the result for the sought dis-

tance “X” is displayed in the result 

line c. The measuring values for the 

distances “1”, “2” and the angle “α” 

are displayed in the measured-value 

lines a.

Pay attention that the reference plane of the measure-

ment (e.g. the rear edge of the measuring tool) re-

mains exactly at the same location for all individual 

measurements within a measuring sequence.

c) Indirect length measurement (see figure E)

Press the function-mode button 4 until the indication 

for indirect length measurement 

 appears on the 

display.

Pay attention that the measuring tool is positioned at 

the same height as the sought measuring point. Now, 

tilt the measuring tool around the reference plane and 

measure distance “1” as for a length measurement.

Upon completion of the measure-

ment, the result for the sought dis-

tance “X” is displayed in the result 

line c. The measuring values for the 

distance “1” and the angle “α” are 

displayed in the measured-value 

lines a.

Wall Surface Measurement (see figure F)

The wall surface measurement is used to determine 

the sum of several individual surfaces with a common 

height.

In the example shown, the total surface of several 

walls that have the same room height A, but different 

lengths B, are to be determined.

For wall surface measurements, press the function-

mode button 4 until the indicator for wall surface 

measurement 

 appears on the display.

Measure the room height A as for a length measure-

ment. The measured value (“cst”) is displayed in the 

top measured-value line a. The laser remains switched 

on.

Afterwards, measure length B

1

 of the 

first wall. The surface is automatically 

calculated and displayed in the result 

line c. The length measurement value 

is displayed in the centre measured-

value line a. The laser remains 

switched on.

Now, measure length B

2

 of the sec-

ond wall. The individually measured 

value displayed in the centre meas-

ured-value line a is added to the 

length B

1

. The sum of both lengths 

(“sum”, displayed in the bottom 

measured-value line a) is multiplied 

with the stored height A. The total surface value is dis-

played in the result line c.

In this manner, you can measure any number of further 

lengths B

X

, which are automatically added and multi-

plied with height A.

The condition for a correct area/surface calculation is 

that the first measured length (in the example the room 

height A) is identical for all partial surfaces.

Grade measurement (see figure G)

After pressing the grade measurement button 3, the 

indication for grade measurement appears on the 

display

. The backside of the measuring tool is 

used as the reference plane. By pressing the grade 

measurement button 3 again, the side surfaces of the 

measuring tool are used as reference plane and the 

display view is shown turned by 90°.

Press the measuring button 2 to lock the measuring 

value and accept it in the measured values memory. 

Pressing the measuring button 2 again continues the 

measurement.

When the indication flashes during the measuring 

procedure, then the measuring tool was tilted too 

much in lateral direction.

If the “digital vial” function is activated in the basic set-

tings, the grade value is also displayed in the other 

measuring functions in line d of display 1.

Timer function

The timer function is helpful, when, for example, move-

ments of the measuring tool during measuring are to 

be prevented.
