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 (5) once more
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).

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 (5) (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.

Indirect measurement

Pythagorean measurement is used in the condition that the objective needing to be measured is covered or has no effective reflecting 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. The minimum / maximum function can be used. The minimum value must be used for measurements at right angles to the target; the maximum distance for all other measurements. 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 continious 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.
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 calculation 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.

• In favorable 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.

MEASURING CONDITIONS

Measuring range

The range is limited to 50 m. At night, at dusk and when the target is shadowed the measuring 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, styrofoam or similar semi-permeable surfaces. Aiming at high gloss surfaces deflects the laser beam and measurement errors can occur. Against non-reflective and dark surfaces the measuring time can be increased.

PRECAUTIONS

Please, handle the instrument with care. Avoid viabrations, hits, water, effect of heat. During transportation put the instrument into the soft bag.
Note: the instrument should be dry!

Care and cleaning

Do not immerse the instrument in water. Wipe off dirt with a damp, soft cloth. Do not use aggressive cleaning agents or solutions.

Specific reasons for erroneous measuring results

• Measurements through glass or plastic windows;
• Dirty laser emitting window;
• After instrument has been dropped or hit. Please check the accuracy;
• Large fluctuation of temperature: if instrument will be used in cold areas after it has been stored in warm areas (or the other way round) please wait some minutes before carrying out measurements;
• Against non-reflective and dark surfaces, colorless surfaces and so on.

Electromagnetic acceptability (EMC)

It cannot be completely excluded that this instrument will disturb other instruments (e.g. navigation systems); will be disturbed by other instruments (e.g. intensive electromagnetic radiation nearby industrial facilities or radio transmitters).
