Operating Instructions
Measuring Range
The measuring range is limited to 328' (100m). If measuring at night or
dusk and the target is in a dark area, the measuring range will increase. To
increase the measurement range during daylight or if the target has poor
reection properties you can use a target plate.
Target Surfaces
Measuring errors can occur when taking measurements of colorless
liquids (e.g. water) or dust free glass, styrofoam or similar semi-permeable
surfaces. Aiming at high gloss surfaces may deect the laser beam and
lead to measurement errors. When measuring against non-reective and
dark surfaces the measuring time may increase.
On and Off
The On/Measure button turns the instrument and laser on. Press the
CLEAR button for a few seconds to turn the instrument and laser off. The
instrument switches off automatically after three minutes of inactivity.
Clear Button
This button cancels the last action and clears the display.
Reference Level Setting
The default reference setting is from
the rear of the instrument. Press the
REFERENCE button to take the
selection from the top of the
instrument. A special beep sounds
whenever the reference setting is
changed. After re-starting the
instrument the reference returns
automatically to the default setting.

Backlight
Press the BACKLIGHT/UNIT button to turn the backlight on and off.
Distance Unit Setting
Hold down the BACKLIGHT/UNIT button for a few seconds to change
the unit of measure. Continue to press the button to toggle between all
units of measure. You can choose between m, ft, in.
Single Distance Measurement
Press the ON/MEASURE button to activate the laser. Press the button
again to trigger the distance measurement. The measured value will be
displayed immediately.
Continuous (Tracking)/Max & Min Measurement
The continuous measurement
function (tracking) is used for the
transferring of measurements.
In continuous measurement mode,
the meter can be moved to the target,
whereby the measured value is
updated approx. every 0.5 seconds.
The corresponding max and min
values are displayed dynamically in
the rst and second line.
For example, the user can move
from a wall to the required distance,
while the actual distance can be
read continuously. For continuous
measurement, press the MAX/MIN
button until the indicator for
continuous measurements appears
on the display. Press it again or press the ON/MEASURE button to stop
the function. The meter resumes normal operation after 100
continuous measurements.

Addition/Subtraction
Press the PLUS button to add the current measurement to the previous
measurement. Press the ON/MEASURE button to add the second
measured value; the result will automatically display.
Press the MINUS button to subtract the current measurement from the
previous measurement. Press the ON/MEASURE button for the result
to be shown in the summary line and the previous measurement will be
shown in the second line. Press the CLEAR button for the last step to
be cancelled. Press the MAX/MIN button to return to single distance
measurement mode.
Area Measurement
Press the AREA/VOLUME button once to enter Area Measurement mode.
The icon will appear on the display to conrm you are in the correct
mode. Press the ON/MEASURE button to take the rst measurement
(ie: length), press the ON/MEASURE button again to take the second
measurement (ie: width). Then the area/surface is automatically
calculated and displayed in the summary line on the display. The previous
measurement will be shown in the second line.
Volume Measurement
Press the AREA/VOLUME button twice to enter Area Measurement
mode. The
the correct mode. Press the ON/MEASURE button to take the rst
measurement (length), press the ON/MEASURE button again to take the
second measurement (width), press the ON/MEASURE button again to
take the third measurement (height). Then the volume is automatically
calculated and displayed in the summary line on the display. The previous
measurement will not be shown.

Indirect Measurement
This is used to determine a distance
using two auxiliary measurements.
Press the INDIRECT MEASUREMENT
button once, the icon will appear
on the display.
Aim at the highest point and press
the ON/MEASURE button to take the
measurement. Holding the instrument
as horizontal as possible press and hold the ON/MEASURE button to
trigger continuous measurement, the horizontal line is measured and
shown in the summary and secondary lines.
Three Point Measurement
Press the INDIRECT MEASUREMENT
button twice, the
on the display. Aim at the highest
point (1) and press the ON/MEASURE
button to trigger the measurement.
Holding the instrument as horizontal
as possible press and hold the
ON/MEASURE button to trigger
continuous measurement and sweep
the laser up and down over the ideal
target point (2), press the
ON/MEASURE button again to
conrm the value. Aim at the lower
point (3) and press the ON/MEASURE
button to trigger the measurement.
The results are shown in the summary
and secondary lines at the same time.
