Introduction
The LASER METER 50 PS 7550 laser distance measurement device is intended
for precision measurement of distances and clearances and for calculation
of surface areas and volumes. In addition, also inaccessible lengths can be
measured by means of indirect distance measurement. Thanks to these and
other functions, it is an ideal measurement device for interior designers,
building companies, real estate agents, craftsmen, etc.

Safety instructions
Injuries can occur if the following instructions are not observed:
1. Please read these Operating Instructions attentively before using the device.
Keep the Instructions for future use.
2. The warning labels on the device shall never be made unrecognizable or
removed from the device.
The device is shipped with warning notices in the German language. Please
paste the attached warning labels in your language over the original ones before
the initial commissioning.
3. Never point the laser beam at the eyes of other persons or animals.
Do not look into the laser beam and do not handle the laser light using
optical equipment. This can damage the eyes.
4. Never let children use the laser meter without surveillance. They can
inadvertently injure themselves or other persons.
5. Do not use the device in flammable or explosive environment. Sparks can
be generated in the device, which may cause fire in the environment.
6. Have the measurement device repaired by qualified professionals only and
using original replacement parts. In such a way, the safety of the device can
be preserved.
Attention: The measurement device may loose its precision by a strong impact
and when falling. Whenever in doubt, perform an accuracy check using a
well known measured distance for the sake of certainty. The measurement
device shall be protected from humidity and strong effects of heat caused e.g.
by direct sunshine. Please provide enough time for the device to adjust to the
ambient temperature.

Operation
Insert/replace the batteries
Open the battery compartment cover at the back of the device by first
loosening the safety screw and then pulling the battery compartment cover
up. Then insert the batteries as indicated in the battery compartment. Then
replace and fix the battery compartment cover.
Attention: Remove the batteries when not using the device for a longer
period of time.
Switch the device on
Press the button “A” and, before measurement, check the activated
reference plane.
Reference plane
Three different reference planes can be selected in the measurement device:

accessible places
To change the reference plane, press the button “L”. The active plane is
indicated in the display under “2–4“. Whenever the measurement device is
switched on, the reference plane is set to the device rear edge.

Measurement functions
Length measurement
Length measurement is preset when the device is switched on. The display
indicates the length measurement symbol. Aim at the end of the measured
distance and press the button “A” again. The reading is indicated below in
the “12” display.
Surface area measurement
Press the button “C” once in order to select surface area measurement. The
display indicates the symbol for surface area measurement, the first surface
length flashes. Aim at the desired target and press the button “A” once to
take the measurement. The reading is indicated above in the “10” display,
while the second surface length flashes. Use the laser to aim at the next target
and press the button “A” to take the measurement. The reading is indicated
in the “11” display, while the resulting surface area has been calculated and
indicated in “12”.
Volume measurement
Press the button “C” twice in order to select volume measurement. The
display indicates the symbol for volume measurement, the first volume length
flashes. Aim at the desired target and press the button “A” to take the first
measurement. The reading is indicated above in the “10”display, while the
second volume length flashes. Use the laser to aim at the next target and press
the button “A” to take the measurement. Proceed in a similar way for the third
length. The reading is indicated in the “11” display, while the resulting volume
has been calculated and indicated in “12”. Indirect length measurement Using
this function you can measure directly inaccessible distances (e.g. exterior wall
heights), as two or three measurable lengths are mutually related based on
trigonometric functions.
Measurement based on two lengths
Press the button “D” once in order to select indirect length measurement.
The display indicates the indirect measurement symbol, the first length flashes.
Aim at the desired target and press the button “A” once to take the first
measurement. The reading is indicated above in the “10” display, while the
second length in the display flashes. Use the laser to aim at the next target and
press the button “A” to take the measurement. The reading is indicated in the
display, while the resulting length has been calculated and indicated in “12”.
Measurement based on three lengths
Press the button “D” twice in order to select indirect length measurement based
on three lengths. The display indicates the indirect measurement symbol, the
first length flashes. Aim at the desired target and press the button “A” once to
take the first measurement. The reading is indicated above in the “10” display,
while the second length in the display flashes. Use the laser to aim at the next
target and press the button “A” to take the measurement. The reading is
indicated in the display. Proceed in a similar way for the third length. The reading
is indicated in the display, while the resulting length has been calculated and
indicated in “12”.
Continuous measurement
The continuous measurement function is intended for deriving dimensions
for instance from construction plans. The minimum and maximum
values can also be determined in this way. When this function is used,
the measurement device moves relative to the target, while the reading is
updated approx. every 0.5 sec. During this, the minimum distance is indicated
in the “10” display and the maximum distance in the “11” display. The
currently measured value is always indicated in the “12” display. Press the
button “5“ for approx. 3 sec until you receive an indication and move the
measurement device. The distances are indicated in the display. To deactivate
the function, press the button “A”. The function switches off automatically
after 100 measurements.
Computing operations
Addition
This is intended to add two or more lengths. When you have measured
the first length, press the add symbol “K”. The reading is indicated above
in the “10” display, while the “+” symbol in the display flashes. Press the
button “A” again, and the total is indicated in the bottom line. You can
add more values in this way.
Subtraction
When you have measured the first length, press the subtract symbol “J”.
The reading is indicated above in the “10” display, while the “–“ symbol in
the display flashes. Press the button “A” again, and the total is indicated in
the bottom line. In this way, you can subtract more values from each other.
Memory function
The memory function contains the 10 last readings. For this purpose, press
the button “G”. The memory values can be scrolled using the Add and
Subtract buttons (buttons “J” and “K”) and thus shown in the display.
Individual readings can be deleted from the list using the Delete button “H”.
Lighting and unit selection button
The display lighting can be switched on and off by pressing the lighting or
unit selection button briefly. When the button is pressed for a longer time,
the unit of measure of the readings changes (m, ft, in, ft+in).
Causes and removal of errors
The device will help you in case of measurement troubles, as various codes
are indicated in the display.
