reference point can be changed

(see “Selecting the Reference

Point”, page 12).

Place the measuring tool with the

selected reference plane against

the desired starting point of the

measurement (e.g. a wall).

Briefly press the measuring

button 2 to switch on the laser

beam.

Aim the laser beam at the

target surface. Briefly press the

measuring button 2 again to

initate the measurement.

In the continuous measurement

mode, the measurement begins

immediately upon switching on

the function.

Typically, the measured value

appears after 0.5 seconds and

latest after 4 seconds. The

duration of the measurement

depends on the distance, the

light conditions and the reflection

properties of the target surface.

The laser beam is switched off

automatically upon completion of

the measurement.

When no measurement has

taken place approx. 20 seconds

after sighting, the laser beam

is switched off automatically to

save the batteries.

SELECTING A REFERENCE

POINT (see figure A)

For the measurement, you

can select between two

reference planes:

– The rear measuring-tool edge

(e.g. when measuring onward

from a wall),

– The front measuring-tool edge

(e.g. when measuring onward

from a table edge),

To select the reference

point, press button 6 until the

requested reference point is

indicated on the display. Each

time after switching on the

measuring tool, the rear edge of

the measuring tool is preset as

the reference point.

CHANGING THE UNIT OF

MEASURE

The unit of measure can be

changed any time for display of

the measured values, even for

already measured or calculated

values.

For display

of the current

length

measurement

values, the

units of

measure shown opposite are

available.

To change the unit of measure,

push button 3 until a new unit of

measure is displayed.

The unit-of-measure setting is

retained when switching the

measuring tool on or off.
