Operation

INITIAL OPERATION

WARNING

against moisture and direct sun light.

Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for longer periods. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. In case of extreme

temperatures or variations in temperature, the accuracy of the measuring tool can be impaired.

Avoid heavy impact to or falling down of the measuring tool. After severe exterior

effects to the measuring tool, it is recommended to carry out an accuracy check (see “Accuracy Check of the Distance Measurement”, page 17) each time before continuing to work.

Switching On and Off

For switching on the measuring tool, the following possibilities are given:

– Pressing the On/Off button 4: The measuring tool is switched on and is in length measurement

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.

DISPLAY ILLUMINATION

The display illumination is automatically activated, depending on the ambient brightness. When no button is pressed after the display illumination switches on, it is switched off to save the batteries.

MEASURING FUNCTIONS Simple Length Measurement

(see figure B)

For length measurements, press button 9 until the “length measurement” indication appears on the display.

To switch the laser on and for measuring, briefly press the

measuring button 2 once each time.

The measured value is displayed in the result line b.

For several subsequent length measurements, the last measured results are displayed in the measured-value lines a.

AREA MEASUREMENT (see figure C)

For area/surface measurements, press button 9 until the indicator for area/surface measurement

appears on the display.

Afterwards, measure the length and the width, one after another, in the

same manner as a length measurement. The laser beam remains switched on between both measurements.

Upon completion of the second measurement, the surface is automatically calculated and displayed in the result line b. The individual measured values are displayed in the measured-value lines a.

VOLUME MEASUREMENT (see figure D)

For volume measurements, press button 9 until the indicator for volume measurement appears on the display.

Afterwards,

measure the

length, width and

the height, one

after another, in the same manner as for a length measurement. The laser beam remains switched on between all three measurements.

Upon completion of the third measurement, the volume is automatically calculated and displayed in the result line b. The individual measured values are displayed in the measured-value lines a.

-13-

Values above 999999m

cannot be indicated; “ERROR”

appears on the display. Divide the volume to be measured into individual measurements; their values can then be calculated separately and then summarized.

CONTINUOUS MEASUREMENT (Tracking) (see figure E)

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 example, you can move a certain distance away from a wall, while the actual distance can always be read.

For continuous measurements, press button 9 until the indicator for continuous measurement appears on the display. To start the continuous measurement, press the measuring button 2.

The current measured value is displayed in the result line b.

Pressing the measuring button

2 ends the

continuous

measurement.

The last

measured value

is displayed

in the result line b. Pressing the measuring button 2 again restarts a continuous measuring run.

Continuous measurement automatically switches off after 5 min. The last measured value remains indicated in the result line b.

DELETING MEASURED VALUES

Briefly pressing button 4 deletes the last individual measuring value determined in all measuring functions. Briefly pressing the button repeatedly deletes the individual measured values in reverse order.

ADDING MEASURED VALUES

To add measuring values, firstly carry out a measurement. Then press the plus button 8. For confirmation, “+” appears on the display. Then carry out a second measurement.

If you add volumes or areas, then the small + sign which is left of the volume/area symbol in the display, appears during the 2nd /

3rd / 4th,....volume measurement

which is added.

To call up the sum of both measurements, press the plus button 8 again.

-14-

The calculation is indicated in the measured-value lines A, and the sum in the b.

After calculation of the sum, further measured values can be added to this result when pressing the plus button 8 prior to each measurement.

Notes on the addition:

– Mixed length, area/surface and volume values cannot be added together. For example, when a length and area value are added, “ERROR” briefly appears on the display after pressing the plus button 8. Afterwards, the measuring tool switches back to the last active measuring mode.

– For each calculation, the result of one measurement is

Working Advice

GENERAL INFORMATION

The reception lens 12 and the laser beam outlet 11 must not be covered when taking a measurement.

The measuring tool must not be moved while taking a measurement (with the exception of the continuous measurement function). Therefore, place the measuring tool, as far as this is possible, against or on a firm stop or supporting surface.

added (e.g. the volume value); for continuous measurements, this would be the displayed measured value in result line b. The addition of individual measured values from the measured-value lines a is not possible.

SUBTRACTING MEASURED VALUES

To subtract measuring values, press minus button 5; For confirmation, “–” is indicated

on the display. The further procedure is analog to “Adding Measured Values”.

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 17 (accessory) and the laser target plate 18 (accessory), or shade off the target surface.

-15-

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).

If required, use the laser target plate 18 (accessory) on these surfaces.

Furthermore, faulty measurements are also possible when sighting inclined target surfaces.

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 permanently unchangeable measuring section with a length of approx. 1 to 30-ft; 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.

The deviation of the individual measurements from the mean value must not exceed ±3/32” (max.). Log the measurements, so that you can compare their accuracy at a later point of time.
