Thank you for purchasing the Laser Distance Meter. The MT150 is
a pen-shaped laser distance meter and was specifically designed
for indoor applications. Shortcut and Soft grip keys for addition,
subtraction, area and volume calculation allow for fast and very
reliable measurement.

3.1. Permitted Use
ŸMeasuring distances.
ŸComputing functions, e. g. areas and volumes.
3.2. Prohibited Use
ŸUsing the instrument without instruction.
ŸUsing outside the stated limits.
ŸDeactivation of safety systems and removal of explanatory and
hazard labels.
ŸOpening of the equipment by using tools (screwdrivers, etc.),
as far as not specifically permitted for certain cases.
ŸCarrying out modification or conversion of the product.
ŸUse of accessories from other manufacturers without the
express approval of by us.
ŸDeliberate or irresponsible behavior on scaffolding, when using
ladders, when measuring near machines which are running, or
near parts of machines or installations which are unprotected.
ŸAiming directly into the sun.
ŸInadequate safeguards at the surveying site (e.g. when
measuring on roads, construction sites, etc.).
4. Laser Classification
There is a visible laser beam which emerges from the front of the
instrument.
Laser Class 2 products:
Do not stare into the laser beam or direct it towards other
people unnecessarily. Eye‘s protection is normally
afforded by aversion responses including the blink reflex.

1. Remove battery compartment lid.
2. Insert batteries, observing correct polarity.
3. Close the battery compartment again.
• Replace the batteries when the symbol
“ “ flashes permanently in the display.
• Use alkaline batteries only.
• Remove the batteries before any long
period of non-use to avoid the danger of
corrosion.

The instrument switches off automatically after three minutes of
inactivity.
8.2. Clear Button
The last action is cancelled or the data display is cleared. If
in the mode of History storage, press MEM button and Clear
button simultaneously will clear all storage data in the
memory.

8.3. Reference Level Setting
The default reference setting is from the rear of the instrument.
Hold down this button to take the selection from the front
edge , a special beep sounds whenever the reference setting is
changed. After a re-startup the reference returns automatically to
the default setting (rear reference).

8.5. Measuring
8.5.1. Single Distance Measurement
Press to activate the laser. Press again to trigger the distance
measurement. The measured value is displayed immediately.
8.5.2. Continuous Measurement (Tracking) & Max and Min
Measurement
The continuous measurement function (tracking) is used for the
transferring of measurements, e.g., from construction plans. In
continuous measurement mode, the measuring tool can be moved
to the target, whereby the measured value is updated approx.
every 0.5 seconds in the third line. The corresponding MIN and
MAX values are displayed dynamically in the first and second line.
As an example, the user can move from a wall to the required
distance, while the actual distance can be read continuously. For
continuous measurement, hold down the button to start the
continuous measurement. Press or button again to stop
the function. The function is terminated automatically after
continuous 100 times measurement.

9.1. Area Measurement
9. Functions
Unit
Press button to take the first length measurement (e.g. length).
The result of the area measurement is displayed in the third line,
the individually measured values are displayed in lines 1 and 2.
Whilst the first connection between the Phone/PC and the Laser
distance meter is being established, a prompt for the Pin-code of
the instrument may be displayed. In this case, enter the code
0000 into your Phone/PC.
Press the button once will start the area measurement function.
Press button again to take the second length measurement
(e.g. width).
9.2. Volume Measurement
Unit
Press button to measure the second distance (e.g. width).
Press button to measure the third distance (e.g. height).
Press button to measure the first distance (e.g. length)
Press the button twice will start volume measurement function.
The result of the area measurement from the values already
measured is displayed in the summary line.
The value is displayed in the second line. The result of the volume
measurement is displayed in the summary line, the two previously
measured values in lines 1 and 2.
9.3. Historical Storage
The previous 20 records (measurements or calculated results) are
shown in the reverse order. Use buttons to navigate through
these records. You can clear all records by pressing the Storage
button and Clear button simultaneously in historical storage mode.

9.5. Switching BLUETOOTH Off
Hold down the button until the Bluetooth symbol disappears in
the display. BLUETOOTH is disabled when the instrument is turned
off.

9.4. Switching BLUETOOTH On
Unit
Hold down the button until the Bluetooth symbol disappears in
the display. Then you can use our Meterbox APP installed on your
phone to connect with this instrument.
10. Measuring Conditions
10.1. Measuring Range
10.2. Target Surfaces
10.3. Care
The range is limited to Technical Specifications.
Measuring errors can occur when measuring toward colorless
liquids (e.g. water) or dust free glass, Styrofoam or similar
semi-permeable surfaces. Aiming at high gloss surfaces may
deflect the laser beam and lead to measurement errors. Against
non-reflective and dark surfaces the measuring time may increase.
Do not immerse the instrument in water. Wipe off dirt with a damp,
soft cloth. Do not use aggressive cleaning agents or solutions.
Handle the instrument as you would a telescope or camera.
10.4. Troubleshooting – Causes and Corrective Measures
Code
208
252
253
255
Cause
Received signal too weak,
measurement time too long.
Distance>50m
Temperature too high
Temperature too low
Hardware error
Corrective Measure
Use target plate
Cool down instrument
Warm up instrument
Switch on/off the device several times,
If the symbol still appears, please
contact your dealer for assistance.

11. Specifications
ŸUse a target plate to increase the measurement range during
daylight or if the target has poor reflection properties.
ŸIn favorable conditions (good target surface properties, room
temperature) up to 10m (33ft). In unfavorable conditions, such
as intense sunshine, poorly reflecting target surface or high
temperature variations, the deviation over distances above
10m (33ft) can increase by ±0.15mm/m (±0.0018in/ft).
