A) The working range increases depending on how well the laser light is reflected from
the surface of the target (scattered, not reflective) and with increased brightness of
the laser point to the ambient light intensity (interior spaces, twilight). In unfavorable
conditions, e.g., with extreme interior illumination or a badly reflecting surface, the
measuring range may be limited.

B) In unfavorable conditions, e.g., with extreme interior illumination, badly reflecting
surface or the room temperature deviating heavily from 77°F (25°C), the maximum
deviation can be up to ±7 mm per 15 m. In favorable conditions, a deviation influence of
±0.05 mm/m must be taken into account.

The measuring tool can be clearly identified with the serial number 5 on the type plate.

Preparation

Inserting/Replacing the Batteries

AAA Alkaline batteries are recommended for the measuring tool.
To open the battery lid 3, press the latch 4 in the direction of

the arrow and remove the battery lid. Insert the batteries. When
inserting, pay attention to the correct polarity according to the
representation on the inside of the battery compartment.

When the battery symbol appears for the first time on the
display, measurements are still possible for approx. 15 minutes.
When the battery symbol flashes, the batteries must be
replaced; measurements are no longer possible.

Always replace all batteries at the same time. Only use
batteries from one brand and with the identical capacity.

Remove the batteries from the tool when not using it for
extended periods. When storing for extended periods, the

batteries can corrode and discharge themselves.

Switching On and Off

Measuring Procedure

-11-

After the measuring tool is switched on, continuous measurement
starts. Aim the laser beam at the target surface.

The current measuring value g is displayed in the bottom line of
the display (see figure A). During continuous measurement, the
measuring tool can be moved relative to the target, whereby the
current measuring value g is updated approx. every 0.5 seconds in
the bottom line of the display (see figure B).

In this manner,as an example, you can move a certain distance
away from a wall, while the actual distance can always be read.
The laser indicator flashes on the display.

The rear edge of the measuring tool is preset as the reference
plane for the measurement.

For a wall to wall measurement, as an example, position the
measuring tool with its rear edge against the initial wall.

No Measurement Being Displayed

All dashes will display when the beam is
moved too fast or if the object is out of range
in continuous mode.

“HOLD” Function (see Figure B)

Press the “On/Off” button 1 to stop the
measuring procedure. The laser beam
is switched off and the HOLD indication
appears on the display.

The current measuring value is still displayed
in the bottom line of the display, but is no
longer continuously updated.

Press the “HOLD” button 1 once more to
switch the laser on again. The laser indicator

flashes on the display. The previous

measuring value is displayed in the top line.
The continuously updated/current measuring
value is displayed in the bottom line.

-12-

Press the “HOLD” button 1 once more to
stop the measuring procedure again. The
laser beam is switched off and the HOLD
indication appears on the display. The
previous measuring value is displayed in
the top line. The current measuring value is
displayed in the bottom line, but is no longer
continuously updated.

When no button on the measuring tool is pressed for approx. 5
minutes, the measuring tool automatically switches off to save the
batteries.

“Err” occurs when trying to hold a measurement
that is out of range or measurement cannot be
read correctly by tool.

Changing the Unit of Measure

The unit of measure can be changed any time for display of the
measured value, even for already measured or calculated values.

Switch off the measuring tool. Press the measuring button 1
and hold it down. The display will alternately show both units
of measure. When the desired setting is displayed, release the
measuring button 1. The setting is saved.

Working Advice

General Information

The reception lens 7 and the laser beam outlet 8 must not be
covered when taking a measurement.

Measurement takes place at the center of the laser beam, even
when target surfaces are at a slope.

Influence Effects on the Measuring Range

The measuring range depends on the light conditions and the
reflection properties of the target surface.

-13-

Influence Effects on the Measuring Result

Due to physical effects, faulty measurements cannot be excluded
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).
Also, air layers with varying temperatures or indirectly received

reflections can affect the measured value.

Accuracy Check of the Distance Measurement

The accuracy of the distance measurement can be checked as
follows:

– Select a permanent measuring section with a length of

approx. 3 ft to 33 ft (1 m to 10 m); its length must be precisely
known (e.g. the width of a room or a door opening). The
measuring distance must be indoors; the target surface for the

measurement must be smooth and reflect well.
– Measure the distance 10 times after another.
The deviation of the individual measurements from the mean value

must not exceed ±1/16” (1.6mm). Log the measurements, so that
you can compare their accuracy at a later point of time.
