Measuring Procedure

After switching on, the measuring tool is always in length

measurement or continuous measurement mode. Other

measuring modes can be switched to by pressing the respec-

tive mode button (see “Measuring Functions”, page 19).

After switching on, the rear edge of the measuring tool is pre-

set as the reference level for the measurement. By pressing

the reference level button 8, the reference level can be

changed (see “Selecting the Reference Level

(see figures A – E)”, page 19).

Upon selection of the measuring function and the reference

level, all further steps are carried out by pushing the measur-

ing button 7.

With the reference level selected, place the measuring tool

against the desired measuring line (e.g. a wall).

Briefly press the measuring button 7 to switch on the laser

beam.

 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.

Aim the laser beam at the target surface. Briefly press the

measuring button 7 again to initate the measurement.

When the laser beam is switched on permanently, the meas-

urement already starts after the first actuation of the measur-

ing button 7. In continuous measurement mode, the measure-

ment starts immediately upon switching on.

The measured value typically appears after 0.5 seconds and

at the latest after 4 seconds. The duration of the measure-

ment depends on the distance, the light conditions and the re-

flection properties of the target surface. The end of the meas-

urement is indicated by a signal tone. The laser beam is

switched off automatically upon completion of the measure-

ment.

When no measurement has taken place approx. 20 seconds

after sighting, the laser beam is switched off automatically to

save the batteries.

Selecting the Reference Level (see figures A – E)

For measuring, you can select between four different refer-

ence planes:

– The rear edge of the measuring tool or the front edge of the

laterally folded-out positioning pin 18 (e.g. when measur-

ing onward from outer corners),

– The tip of the folded-out positioning pin 18 (e.g. when

measuring from a corner),

– The front measuring-tool edge (e.g. when measuring on-

ward from a table edge),

–The thread 21 (e.g. for tripod measurements).

To select the reference level, press button 8 until the request-

ed reference level is indicated on the display. Each time after

switching on the measuring tool, the rear end of the measur-

ing tool is preset as the reference level.

Subsequent changing of the reference level for measure-

ments that have already been carried out (e.g. when indicat-

ing measuring values in the measured-value list) is not possi-

ble.

Continuous Laser Beam

If required, the measuring tool can also be switched to the

continuous laser beam mode. For this, push the button for

continuous laser beam 2. “LASER” lights up continuously in

the display.

 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.

In this setting, the laser beam also remains switched on be-

tween measurements; for measuring, it is only required to

press the measuring button 7 once.

To switch off the continuous laser beam, press button 2 again

or switch the measuring tool off.

Switching off the continuous laser beam during a measure-

ment automatically ends the measurement.

Display Illumination

The display illumination is switched on and off by pressing

button 11. When no button is pressed 10 s after switching on

the display illumination, it is switched off to save the batter-

ies.

Audio Signal

To switch the audio signal on and off,

press the function-mode button 3 un-

til the “audio-signal adjustment” indi-

cation appears on the display. Select

the required setting by pressing the

plus button 6 or the minus button 12.

The selected audio-signal adjustment

is retained when switching the measuring tool off and on.

Changing the Unit of Measure

For indication of the measured values, the unit of measure can

be changed at any time.

The following units of measure are possible:

– Length measurement: m, cm, mm,

– Area/surface measurement: m

– Volume measurement: m

To to change the unit of measure,

press the function-mode button 3 un-

til the “change unit of measure” indi-

cation appears on the display. Select

the required unit of measure by

pressing the plus button 6 or the mi-

nus button 12.

Measuring Functions

Simple Length Measurement

For length measurements, press button 4 until the “length

measurement” indication appears on the display.

Press the measuring button 7 once

for sighting and once more to take the

measurement.

The measured value is displayed in

the result line c.

For several subsequent length measurements, the last meas-

ured results are displayed in the measured-value lines a.

Continuous Measurement (Tracking)

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 ex-

ample, you can move a certain distance away from a wall,

while the actual distance can always be read.

For continuous measurements, firstly select the length meas-

uring mode and then press the measuring button 7 until the

“indicator for continuous measurement” appears on the

display. The laser is switched on and the measurement starts

immediately.

The current measured value is dis-

played in the result line c.

Briefly pressing the measuring button

7 ends the continuous measurement.

The last measured value is displayed

in the result line c. Pressing the meas-

uring button 7 for several seconds re-

starts a continuous measuring run.

Continuous measurement automatically switches off after

5 min. The last measured value remains indicated in the result

line c.

Minimum/Maximum Measurement (see figure F–G)

The minimum measurement is used to determine the shortest

distance from a fixed reference point. It is used, as an exam-

ple, for determining plumb lines or horizontal partitions.

The maximum measurement is used to determine the greatest

distance from a fixed reference point. It is used, as an exam-

ple, for determining diagonals.

For simple minimum/maximum measurement, firstly select

“length measurement mode” and then press button 13. “min”

is displayed in result line c for minimum measurement. For

maximum measurements, press button 13 again, so that

“max” is displayed in the result line. Then press the measur-

ing button 7. The laser is switched on and the measurement

starts.

Move the laser back and forth over the requested target (e.g.,

the room corner for determining the diagonal) in such a man-

ner that the reference point of the measurement (e.g., the tip

of the positioning pin 18) always remains at the same loca-

tion.

Depending on the set mode, the mini-

mum or maximum value is displayed

in the result line c. It is always over-

written, when the current length

measurement value is less than the

present minimal or larger than the

present maximal value. The maximal

(“max”), the minimal (“min”) and

the current measuring value are displayed in the measured-

value lines a.

To end the minimum/maximum measurement, briefly press

the measuring button 7. Pressing the measuring button again

starts a new measurement.

The minimum/maximum measurement can also be used for

length measurements within other measuring modes (e.g. ar-

ea/surface measurement). For this, press button 13 once for

minimal measurement and twice for maximal measurement

each time when determining individual measured values.

Then press the measuring button 7 to switch the laser beam

on. Move the measuring tool in such a manner that the desired

minimum or maximum value is measured, and press the

measuring button 7 to take over the minimum or maximum

value into the current calculation.

For time-delayed length measurements and when in mark-out

mode, minimum/maximum measurements are not possible.

The minimum/maximum measurement automatically switch-

es off after 5 min.

Area Measurement

For area/surface measurements, press button 4 until the indi-

cator for area measurement appears on the display.

Afterwards, measure the length and the width, one after an-

other, in the same manner as a length measurement. The laser

beam remains switched on between both measurements.

Upon completion of the second meas-

urement, the surface is automatically

calculated and displayed in the result

line c. The individual measured values

are displayed in the measured-value

lines a.

Volume Measurement

For volume measurements, press button 4 until the indicator

for volume measurement appears on the display.

Afterwards, measure the length, width and the height, one af-

ter another, in the same manner as for a length measurement.

The laser beam remains switched on between all three meas-

urements.

Upon completion of the third meas-

urement, the volume is automatically

calculated and displayed in the result

line c. The individual measured values

are displayed in the measured-value

lines a.

Values above 999999 m

cannot be indicated; “ERROR” and

“––––” appear on the display. Divide the volume to be

measured into individual measurements; their values can

then be calculated separately and then summarized.

Indirect Length Measurement (see figures H–K)

The indirect length measurement is used to measure distanc-

es that cannot be measured directly because an obstacle

would obstruct the laser beam or no target surface is available

as a reflector. Correct results are achieved only when the right

angles required for the respective measurement are exactly

adhered to (Pythagorean Theorem).

Pay attention that the reference point of the measurement

(e.g. the rear edge of the measuring tool) remains exactly at

the same location for all individual measurements within a

measuring sequence (exception: trapezium measurements).

The laser beam remains switched on between the individual

measurements.

For indirect length measurements, four measuring modes are

available. Each measuring mode can be used for determining

different distances. To select the measuring mode, press the

function-mode button 3 until the symbol of the desired meas-

uring mode is indicated on the display.

a) Simple Pythagoras Measurement (see figure H)

Press the function-mode button 3 until the indication for sim-

ple Pythagoras measurement appears on the display.

Measure distances “1” and “2” in this sequence with a length

measurement. Pay attention that a right angle exists between

distance “1” and the sought distance “E”.

Upon completion of the last measure-

ment, the result for the sought dis-

tance “E” is displayed in the result

line c. The individual measured values

are displayed in the measured-value

lines a.

b) Double Pythagoras Measurement (see figure I)

Press the function-mode button 3 until the indication for dou-

ble Pythagoras measurement appears on the display.

Measure distances “1”, “2” and “3” in this sequence with a

length measurement. Pay attention that a right angle exists

between distance “1” and the sought distance “E”.

Upon completion of the last measure-

ment, the result for the sought dis-

tance “E” is displayed in the result

line c. The individual measured values

are displayed in the measured-value

lines a.

c) Combined Pythagoras Measurement (see figure J)

Press the function-mode button 3 until the indication for com-

bined Pythagoras measurement appears on the display.

Measure distances “1”, “2” and “3” in this sequence with a

length measurement. Pay attention that a right angle exists

between distance “1” and the sought distance “E”.

Upon completion of the last measure-

ment, the result for the sought dis-

tance “E” is displayed in the result

line c. The individual measured values

are displayed in the measured-value

lines a.

d) Trapezium Measurement (see figure K)

Press the function-mode button

3 until the indication for tra-

pezium measurement appears on the display.

Measure distances “1”, “2” and “3” in this sequence with a

length measurement. Pay attention that the measurement of

distance “3” starts exactly at the end point of distance “1”

and that a right angle exists between distances “1” and “2” as

well as between “1” and “3”.

Upon completion of the last measure-

ment, the result for the sought dis-

tance “E” is displayed in the result

line c. The individual measured values

are displayed in the measured-value

lines a.

Time-delayed Length Measurement

Time-delayed length measurement is helpful e.g. when meas-

uring at hard to reach locations or when movements of the

measuring tool during measuring are to be prevented.

For a time-delayed length measurement, press function-

mode button 3 until the indicator for time-delayed length

measurement appears on the display.

The time period from the actuation until the measurement

takes place is displayed in the measured-value line a. The time

period can be adjusted between 1 s and 60 s by pressing the

plus button 6 or the minus button 12.

Then press the measuring button 7 to

switch the laser beam on and aim at

the target point. Press the measuring

button 7 again to actuate the meas-

urement. The measurement takes

place after the set time period. The

measured value is displayed in the re-

sult line c.

The addition and subtraction of measuring results as well as

minimum/maximum measurements are not possible for time-

delayed length measurements.

Wall Surface Measurement (see figure L)

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 but-

ton 3 until the indicator for wall surface measurement ap-

pears on the display.

Measure the room height A as for a length measurement. The

measured value (“cst”) is displayed in the top measured-val-

ue line a. The laser remains switched on.

Afterwards, measure length B

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.
