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.

Now, measure length B

of the sec-

ond wall. The individually measured

value displayed in the centre meas-

ured-value line a is added to the

length B

. The sum of both lengths

(“sum”, displayed in the bottom

measured-value line a) is multiplied

with the stored height A. The total

surface value is displayed in the result line c.

In this manner, you can measure any number of further

lengths B

, which are automatically added and multiplied with

height A.

The condition for a correct area/surface calculation is that the

first measured length (in the example the room height A) is

identical for all partial surfaces.

For a new wall surface measurement with new room height A,

press button 16 three times.

Mark-out Mode (see figure M)

Mark-out mode is used for marking off a fixed length (mark-

out value), which can either be measured or entered. It is

helpful for, e.g., marking partition spaces for drywalls.

To activate the mark-out mode, press the function-mode but-

ton 3 until the mark-out mode indication appears on the

display.

The mark-out value can be adjusted as follows:

– To enter a known value, press the plus button 6 or the mi-

nus button 12 until the desired value is displayed in the up-

per measured-value line a. When pressing and holding the

plus button 6 or minus button 12, the values will continu-

ously skip through. The laser is not activated yet.

– For measuring the mark-out value, briefly press the meas-

uring button 7 once for sighting and once more for measur-

ing. Afterwards, the laser beam remains switched on.

– The measured or entered mark-out value can be corrected

by pressing the plus button 6 or the minus button 12.

After determining the mark-out value, press and hold the

measuring button 7 to begin the measurement.

Now, move the measuring tool in the desired direction for

marking out. The current measuring value of the complete

measured distance is continuously displayed in the result line

c. The selected mark-out value continues to be displayed in

the upper measured-value line a.

The factor (“x”) how often the mark-out value is contained in

the total measuring distance is displayed in the centre meas-

ured-value line, and the difference (“dif”) between an inte-

gral multiple of the mark-out value and the total distance is

displayed in the bottom measured-value line a.

When the total measuring distance is somewhat less than an

integral multiple, then a negative difference and the next high-

er multiple of the mark-out value are displayed.

Move the measuring tool until the desired multiple of the

mark-out value is displayed in the centre measured-value line

a and the difference in the bottom measured-value line is a

“0.0 m”. Then mark off the reference point of the measure-

ment.

Examples:

a) Positive difference:

7.4m=(12x0.6m)+0.2m

The mark-out value 0.6 m is con-

tained 12x in a total distance of

7.4 m. Additionally, the total distance

contains a rest of 0.2 m. Reduce the

distance between the measuring tool

and the starting point by 0.2 m differ-

ence, and then mark off the length.

b) Negative difference:

7.0 m = (12 x 0.6 m) – 0.2 m

For a total distance of 7.0 m, 0.2 m

are missing for the mark-out value

0.6 m to be contained 12x. Increase

the distance between the measuring

tool and the starting point by 0.2 m

difference, and then mark off the

length.

Briefly pressing measuring button 7 ends the mark-out mode.

Pressing and holding the measuring button 7 restarts the

mark-out mode anew (with the same mark-out value).

The mark-out mode automatically switches off after 5 min.

For prior exiting of the function, press one of the measuring-

mode buttons.

List of the last Measuring Values

The measuring tool stores the last 30 measuring values and

their calculations, and displays them in reverse order (last

measured value first).

To recall the stored measurements,

press button 15. The result of the last

measurement is indicated on the dis-

play, along with the indicator for the

measured-value list d as well as a

counter for the numbering of the dis-

played measurements.

When no further measurements are stored after pressing but-

ton 15 again, the measuring tool switches back to the last

measuring function. To exit the measured-value list, press

one of the measuring-mode buttons.

To delete the currently displayed measured-value list entry,

briefly press button 16. To delete the complete measured-

value list, press and hold the button for the measured-value

list 15 and at the same time briefly press button 16.

Deleting Measured Values

Briefly pressing button 16 deletes the last individual measur-

ing value determined in all measuring functions. Briefly press-

ing the button repeatedly deletes the individual measured val-

ues in reverse order.

In wall surface measurement mode, briefly pressing button

16 the first time deletes the last individually measured value;

pressing the button a second time deletes all lengths B

, and

pressing the button a third time deletes all room heights A.
