calculation make measuring fast and very reliable.

1. Safety Instruction
Permitted Use
 Measuring distances
 Computing functions, e.g. areas and volumes
Prohibited Use
 Using the instrument without instruction
 Using outside the stated limits
 Deactivation of safety systems and removal of
explanatory and hazard labels
 Opening of the equipment by using tools
(screwdrivers, etc.), as far as not specifically
permitted for certain cases
 Carrying out modification or conversion of the
product
 Use of accessories from other manufacturers without
the express approval of Marmonix Technology
 Deliberate 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
 Aiming directly into the sun
 Inadequate safeguards at the surviving site (e.g.
when measuring on roads, construction sites, etc.)

 Laser Classification
 The Marmonix produced 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 a version responses including the blink
reflex.
 WARNING:
 Looking directly into the beam with optical aids
 (e.g. binoculars, telescopes) can be hazardous.
 Precautions:
 Do not look directly into the beam with optical aids.
 CAUTION:
 Looking into the laser beam may be hazardous to the
eyes.
 Precautions:
 Do not look into the laser beam. Make sure the laser is
aimed above or below eye level.

2. Start-Up
Inserting/replacing
batteries (see
“Figure A”)
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.

3. Initial Operating and Setting
Switching On and Off
Switches on the instrument and laser
Press this button longer to switch of the instrument
The instrument switches off automatically after three
minutes of inactivity.
Clear Button
The last action is cancelled or the data display is
cleared. If in the mode of History storage, press
Storage button and Clear button simultaneously will
clear all storage data in the memory.
Reference Level Setting (See “Figure D”)

The default reference setting is from the rear of the
instrument.
Press this button to take 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).

Display Illumination
Click illumination/ UNITS button of the display can
be switched on or off, user can trigger the function
when he/she is in darkness situation. The value is clear
visible o the LCD.
Distance Unit Setting For Instrument
Click the button longer to change the next type of
unit, m, ft.in, ft+in then continue to click the button for
the next unit selection
4. Measuring
Single Distance Measurement
Press to activate the laser
Press again to trigger the distance
measurement. The measured value is displayed
immediately.
Continuous Measurement (Tracking) & Max and Min
Measurement (see “Figure E”)

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
minimum and maximum 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, push button until the
indicator for continuous measurement appears in the
display. And press MEAS or Clear button again to stop

the function. The function is terminated automatically
after continuous 100 times measurement.
5. Functions
Addition/ Subtraction
Distance measuring.
The next measurement is added to the previous
one.
The next measurement is subtracted from the
previous one.
The last step is cancelled.
Return to the single distance measurement
Area Measurement
Press the Area/Volume button. The symbol
appears in the display.
Press button to take the first length
measurement (e.g. length).
Press again to take the second length
measurement (e.g. width).
The result of the area measurement is displayed in the
third line, the individually measured values are
displayed in line 1 and 2.

Volume Measurement
For volume measurements, push Area/Volume button,
twice until the indicator for volume measurement
appears in the display. Afterwards,
press to takes first distance measurement (e.g.
length)
press to takes second distance measurement (e.g.
width)
the result of the area measurement from the values
already measured is displayed in the summary line.
Press to takes the third distance measurement
(e.g. height). The value is displayed in the second line.
The result of the area measurement is displayed in the
third line, the two previously measured values in line 1
and 2.
Indirect Measurement
Indirect measurement – determining a distance using 2
auxiliary measurements ( See ‘FigureG”).
e.g. when measuring heights that require the
measurement of two or three measurements as
following step:

Press this button once, the display shows.
The distance to be measured flashes in the symbol.
Aim at the upper point (1) and trigger the
measurement.
After the first measurement the value is adopted. Keep
the instrument as horizontal as possible.
Press to measurement the distance result of the
horizontal point (2).
The result of the function is displayed in the summary
line.

Indirect Measurement – Determining a Distance Using 3
measurements ( See “ Figure H”)
Press this button twice; the display shows the
symbol. The distance to be measured flashes in the
symbol.
Aim at the lower point (1) and trigger the
measurement. After the first measurement the value is
adopted. Keep the instrument as horizontal as
possible.
Press to measurement the distance result of the
horizontal point (2).
Press to measurement the distance result of the
upper point (3).
The result of the function is displayed in the summary
line.
Historical Storage
the previous 20 records (measurement or
calculated results) are shown in the reverse order. Use

the or buttons to navigate through these
records.
You can clear all records by press Storage button and
Clear button simultaneously in historical storage mode.

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

8. Measuring Conditions

Measuring Range
The range is limited to 50m.
At night or dusk and if the target is in shadow the
measuring range without target plate is increased. Use
a target plate to increase the measurement range
during daylight or if the target has poor reflection
properties.
Target Surfaces
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.
Care
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.
