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.

	Initial Operation
	Protect the tool against moisture and
! WARNING
	direct sun irradiation.

Do not subject the 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 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 tool can be impaired.

Avoid heavy impact or falling of the tool. After heavy exterior impact on the tool, an accuracy check should always be carried out before continuing to work (see “Accuracy Check of the Distance Measurement”, page 14) each time before continuing to work.

Do not point the laser beam at persons or animals and do not look into the laser

beam yourself, not even from a large distance.

Do not leave the switched on measuring tool unattended and switch the tool off after use. Other persons could be blinded by the laser beam.

Switching On and Off

To switch on the measuring tool, push down the On/Off button 1. When switching on the measuring tool, the laser beam is switched on. The laser indicator flashes on the display.

To switch off the measuring tool, push down the On/Off button 1 and hold for 3 seconds.

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

Measuring Procedure

Measurements are taken from the rear edge of the tool as indicated by icon located on the tool’s rubber overmold.

-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.
