SAFETY INSTRUCTION
Prohibited use
Please follow up instructions given in operating manual.
Do not use instrument in explosive environment (filling station, gas equipment, chemical production and so on).
Do not remove warning labels or safety instructions.
Do not open instrument housing, do not change it’s construction or modification.
Do not stare at beam. Laser beam can lead to eye injury (even from greater distances).
Do not aim laser beam at persons or animals.
Opening of the equipment by using tools (screwdrivers, etc.), as far as not specifically permitted for certain cases.
Inadequate safety precautions at the surveying site (e.g. when measuring on the roads, construction sites and so on).
Use the instrument in the places where it could be dangerous: on the air transport, near manufacturers,
production facilities, in the places where the work of laser distance meter can lead to the harmful effects on
people or animals.

MEASUREMENTS
Single distance measurement
Press button (1) to activate the laser. When in continuous laser mode, press this button to trigger the distance measure-
ment directly. The instrument will give acoustical signal.
The result is displayed immediately.
Continuous Measurement
Press and hold the button (1) for about 2 seconds to start continuous measuring.
Minimum/ Maximum measurement
This function allows the user to measure the minimum or maximum distance from a fixed measuring point. It is com-
monly used to measure room diagonals (maximum values) or horizontal distances (minimum values).
Press and hold down the button (1), until you will hear acoustical signal. Then slowly sweep the laser back and forth

and up and down over the desired target point (e.g. into the corner of a room).
Press (1) to stop continuous measurement. The values for maximum and minimum distances are shown on
the display as well as the last measured value in the main line.
FUNCTIONS
Distance measuring
Press button (5): next measurement is added to the previous one. Press button (3): next measurement is substracted
from the previous one.
To complete this function press button (1). Repeat this function to measure distances. The result is des-
played in the main display area. Previous measured value is displayed in the first line, last measured value
is displayed in the second line. To finish working in this mode press button (4).

COSMO 70 11
Area
Press the button (2) once.The symbol “area” is displayed.
Press button (1) to take the first measurement (for example, length). Measured value is displayed in the
second line.
Press button (1) to take the second measurement (for example, width). Measured value is displayed in the
second line. First measurement (e.g. length) is displayed in the first line. The result of measured area is
displayed in the main display area.
Addition / Subtraction of areas
Area measuring – see Area.
Take the first measurement of area. Press button (5) to enter into the Addition mode or button (3) to enter
into the Subtraction mode. Area value is displayed in the second line.
Press button (1) to take the first measurement (for example, length). Press button (1) to take the second
measurement (for example, width).

COSMO 70
12
After the completion of area, press button (1) , the result of addition/substraction of areas is displayed in
the main display area. If the measurements are not finished, press button (5) (addition) or (3) (substraction)
to continue calculations.
Volume
For volume measurements, press button (2) twice until the indicator for volume measurement appears on
the display.
Press button (1) to take the first measurement (for example, length). Measured value is displayed in the
second line.
Press button (1) to take the second measurement (for example, width). Measured value is displayed in the
second line. Area value is displayed in the first line.
Press button (1) to take the third measurement (for example, height). Measured value is displayed in the
second line.
The volume value will be displayed in the main display area and the previous area value is displayed in the first line.

COSMO 70 13
Indirect measurement
Pythagorean measurement is used in the condition when the object is covered or has no effective reflect-
ing surface and can’t be measured directly.
Make sure you adhere to the prescribed sequence of measurement:
All target points must be in a horizontal or vertical plane.
The best results are achieved when the instrument is rotated about a fixed point (e.g. with the positioning
bracket fully folded out and the instrument placed on a wall) or the instrument is mounted on a tripod.
Continious measurements can be used. This function is used for minimum/maximum measurements.
The minimum value must be used for measurements at right angles to the target; the maximum distance
for all other measurements.
Be sure that the first measurement and distance are measured at right angles. Use indirect measurement
function.

Indirect measurement – determing a distance using 2 auxilary measurements
This function is used when height and distance can’t be measured directly.
Press button (2) 3 times. The symbol “triangle” is displayed. The distance to be measured is blinking in the symbol
triangle.
Press button (1) to take distance measuring (hypothenuse of triangle). The result is displayed in the second line. This
measurement can be taken in the indirect measurement function. Press and hold button (1) for 2 sec. After second
pressure of the button (1) maximum value is fixed.
The second distance to be measured is blinking in the symbol triangle.
Press button (1) to take distance measuring. There is a right angle between laser beam and the length you need to
measure.That’s why you should work in continious mode. Press and hold button (1) for 2 sec.After second pressure
of the button (1) maximum distance is fixed. The result of the measurement is displayed in the second line. Previous
measurement is displayed in the first line. The result of the function is displayed in the main display area.

COSMO 70 15
Indirect measurement – determing a distance using 3 measurements
This function is used when it’s necessary to measure diagonals of rectangular areas, and also for calcula-
tion of the length of frameworks, inclined distances and so on.
Press button (2) 4 times. The symbol “triangle” is displayed. The distance to be measured is blinking in
the symbol triangle.
Press button (1) to take distance measuring (side of the triangle) . The result of the function is displayed
in the second line. This measurement can be taken in the mode of continious measurement. Press and hold
button (1) for 2 sec. After second pression of the button (1) maximum value is fixed. The second distance to
be measured is blinking in the symbol triangle. It’s very important to have right angle between laser beam
and the length you need to measure. That’s why you should work in continious mode. Press and hold button
(1) for 2 sec. After second pressure of the button (1) maximum distance is fixed. The result of the function
is displayed in the main display area. Previous measurement is displayed in the first line.

Timer
Use timer for accurate measurements of large distances. Press and hold button (3) to set stoppage in 5 sec.
When you release button you will see time that remains till the beginning of the measurement (in sec).
Time displays on the display. Time reading of last 5 sec. comes with acoustic signal. When you hear last
signal, the instrument takes a measurement.
MESSAGE CODES
All message codes are displayed with either “Info” or symbol telephone receiver (Error). Following mis-
takes can be corrected.

* In favourable conditions (good target surface properties, room temperature).
Maximum deviation occurs under unfavorable conditions such as bright sunlight or when measuring to
poorly reflecting or very rough surfaces. Use target plate for accurate results.
Measuring conditions
Measuring range: the range is limited to 70 m. At night, at dusk and when the target is shadowed the mea-
suring range without target plate is increased. Use a target plate to increase the measurement range during
daylight or if the target has a bad reflection.
Measuring Surfaces
Measuring errors can occur when measuring toward colorless liquids (e.g. water) or dust free glass, styro-
foam or similar semi-permeable surfaces. Aiming at high gloss surfaces deflects the laser beam and mea-
surement errors can occur. Against non-reflective and dark surfaces the measuring time can be increased.
