WARNING
WARNING
Laser beam
Eye damage or risk of accident due to glare are possible in case of eye contact with the laser beam.
•
Never look directly into a laser beam or its reflections!
•
If the laser beam hits your eye, close your eyes and immediately turn your face away from the laser beam.
Normally, eyes close automatically due to the blink reflex and aversion responses take place.
•
Do not point the laser beam at persons or animals.
•
Do not leave the unit switched on unnecessarily.
Opening the device
Eye damage or risk of accident due to glare are possible in
case of eye contact with the laser beam when opening the
device.
•
Do not open the device (except for the battery
compartment).
•
Please contact your specialty retailer or the returns
management for any repairs.
Operation
- Switching the device ON:
/
, Switching the device OFF:
>2 seconds
- Opening the menu:
- Menu navigation:
Left
/ Right
/ Confirm
/ Back
- Starting measurement:
- Please note that for many of the measuring functions, the respective function of the keys is
shown on the digital display.
- Changing the reference plane:
(the set reference plane is shown in the respective
symbol on the digital display)
- Offset of protective rubber holster:
>2 seconds
(A green frame at the respective symbol on the digital display shows that the protective
rubber holster has been factored.)
- Please note that for many of the measuring functions, the length to be measured or the
measured value determined and displayed is indicated on the digital display by the
respective part of the measuring function symbol flashing.
Measurements and functions
Requirements for measuring
- Please consider the brightness of the surrounding light conditions:
•
The ambient light must not be too bright.
•
Avoid measuring in direct sunlight.
- Avoid measuring towards reflective, transparent or very porous surfaces.
- Make sure that the laser beam outlet and the receiving lens are not covered.
- Make sure that the device does not move during the measurement (exception: continuous
measurement).
- Select the reference plane according to the application.
- Select the desired measurement or calculation from the menu.
Length measurement (single measurement)
The length measurement (single measurement) is intended for
measuring a distance between the device and an opposite
surface. After being switched on, the device is automatically in
this measuring function.
1. Point the laser beam at the measuring point (A).
2. Press the “Measurement” key.
The measurement is started and the measured value will be
shown on the digital display.
Length measurement (continuous measurement)
Length measurement (continuous measurement) is intended for
continuously measuring a changing distance. In addition to the
currently measured distance, the shortest and the longest
measured distance of the measurement series are shown on the
digital display.
1. Point the laser beam at the measuring point.
The measured value will be shown on the digital display and
updated when the distance changes.
Area calculation
The area calculation function is intended for determining the area
of a rectangular surface by measuring two measured lengths that
are perpendicular to each other.
1. Point the laser beam at the first measuring point (A).
2. Press the “Measurement” key.
The measurement is started and the measured value (L) will
be shown on the digital display.
3. Point the laser beam at the second measuring point (B).
4. Press the “Measurement” key.
The measurement is started and the measured value (W) will
be shown on the digital display.
The device calculates the area from the two measurements and the determined value will
be shown on the digital display.
Volume calculation
The volume calculation function is intended for determining the
volume of a rectangular space by measuring three measured
lengths that are perpendicular to each other.
1. Point the laser beam at the first measuring point (A).
2. Press the “Measurement” key.
The measurement is started and the measured value (L) will
be shown on the digital display.
3. Point the laser beam at the second measuring point (B).
4. Press the “Measurement” key.
The measurement is started and the measured value (W) will
be shown on the digital display.
5. Point the laser beam at the third measuring point (C).
6. Press the “Measurement” key.
The measurement is started and the measured value (H) will be shown on the digital
display. The device calculates the volume from the three measurements and the
determined value will be shown on the digital display.
