VERTICAL

ADA VERTICAL presents the instrument of vertical projection with laser emitter, class 2. Do not look into the laser beam and do not aim at other persons.

1. Description and application

1) Transmission of planned position with the help of optical method or laser beam;

2) Bright visible red laser beam (635nm);

3) Brightness adjustment of laser beam;

4) Adjustment of diameter of laser spot to increase measurement accuracy;

5) Laser target with reticular division;

6) Bubble levels with LED backlight;

Laser beam is combined with axis of sight of telescope. Such alignment is very convenient when measuring. Because it’s possible to make optical and laser measurements simultaneously. With the help of telescope it’s possible to control the position of laser spot and transmit planned position of the dot in vertical direction. Instrument of vertical projection is widely used by professionals for control when building elevator well, setting supports for high-tension lines, building bridges and tunnels, skyscrapers, water towers, chimneys and for other works where it’s necessary to have constant control.

4. Preparation before operation

Insert the batteries

Remove battery compartment cover (3) and insert 2 batteries type AA observing the polarity.

Mounting the instrument on the tripod

Place the tripod on the construction site. Place the instrument on the tripod and tighten the central screw properly. Adjust the height of the tripod for convenient operation with instrument. Adjust legs of the tripod, so that the bubble of circular level (7) is exactly in the center of the level.

Leveling of the instrument

Coarse leveling with circle bubble:

1) Turn the foot screws A and B to enable the bubble of circular level (7) to position itself on the line that is parallel to the line that goes through the foot screws A and B (pic.2).

2) Turn the foot screw C to enable bubble to position itself in the center of circular level (7) (pic.3). Note: Circular bubble level is only used for leveling the instrument when mounting on the tripod. Leveling before measurements is made with tubular level.

Fine adjustment with tubular level:

1) Turn the instrument in order to make the tubular level (13) parallel to the

line that goes through the foot screws A and B (pic.4);

2) Turn the foot screws A and B to make the bubble move into the middle of tubular level (13);

3) Turn the instrument so that the tubular level (13) will be perpendicular the line that goes through the foot screws A and B. Turn the foot screw C to make the bubble move into the middle of tubular level (pic.5);

4) Repeat above described procedure only after turning the instrument, so

that the bubble will be in the center of tubular level.

Switch-on

1) Turn laser screw (5) to turn on laser dot of the marker of plumb down. Bright laser spot is projected on the target. Continue to turn screw (5) to adjust the brightness of the laser spot;

2) Loosen central screw of the tripod. Move the instrument carefully on the tripod until the laser dot is on the reference point;

3) Repeat steps 4.3.2 for ne leveling of the instrument. Be sure, laser dot must be on the reference point.

Preparation before vertical measurements

Place laser target onto the place of the reference point. Turn screw (4) to switch on laser dot of the marker of plumb up. Rotate

focusing screw (2) to get accurate image of laser dot and marking on the laser target. If you need to increase the accuracy you can use the method of the measurement of diameter:

1) Turn the graduated limb so that zero on the scale coincide with hairline on the housing of the instrument;

2) Mark up the position of laser dot;

3) Turn the instrument by 180° and mark up new position of laser dot; Middle point between these two points is the reference point.

5. Measurements

Vertical measurements

1) Watch laser target and laser marker in the eyepiece of the instrument. If necessary, adjust sharpness of manual focusing;

2) Laser target can be moved vertically for transmission of reference point on desired height;

3) As a result you will get reference point. Line that connects these two points will be vertical.

Vertical measurements in wells

Such measurements can be used in mine survey and engineering surveying. E.g. transfer of line (of given direction). As it is shown in the picture 6, lines A and B are known reference mark. Part of this line goes under well. There are two additional dots C and D on this line. Transmission is made following way:

1) Place the instrument in the bottom of the well. Be sure, laser plumb (zenith) must coincide with dot C;

2) Laser plumb down marks dot E, which will be the projection of dot C;

3) Do the same transmission of the dot D. Dot F is the projection of dot D;

4) If you connect dots E and F you will get line that is parallel AB.

6. Adjustment of the instrument

Adjustment of the tubular level

Axis of the level must be perpendicular to the rotation axis of the theodolite. Turn the alidade of the instrument, so that the axis of tubular level will be parallel to the imaginary line, that connects centers of any 2 foot screws of the tribrach. Rotate these 2 screws in opposite directions, so that the bubble will be in the center of level. Rotate alidade of the instrument by 90° and with the help of third screw place the bubble in the center. Rotate alidade of the instrument by 90° once more. If necessary, place the bubble in the center of the level. Rotate alidade

of the instrument by 180°. It’s necessary to make further adjustment, if the offset of the bubble is more than 1 graduation. Half of the value of bubble deviation is necessary to improve with the help of foot screws. Another half – with the help of adjustment screw of tubular level.

Adjustment of circle level

After adjustment of tubular level, it’s necessary to adjust circular level. If the bubble deviate from the center, adjust its position with the help of three adjusting screws, which are located under the level (pic.7).

Adjustment of collimation error

Rotate the alidade by 180°, observing the center of croosshair of the target in the lens. If you see the offset of the crosshair of reticule relatively the crosshair of the target, it’s necessary to make adjustment:

1) Place the instrument on the tripod or special stand;

2) Aim at the target at range 40 m outside and focus the image;

3) Turn the alidade of the instrument by 180°, observing the offset of reticule;

4) Adjust the position of reticule with the help of 4 adjusting screws, as shown in

the picture 8. Remove the offset by half;

5) Turn the alidade of the instrument by 180°. Repeat the adjustment by removing the offset completely.

Adjustment of the offset of laser beam

Collimation error between optical and laser axis occurs, If laser spot and the center of reticule don’t coincide. For adjustment :

1) Place the instrument on the tripod or special stand;

2) Aim at the target at range 40 m outside and focus the image;

3) Rotate the adjusting screw, as shown in the picture 9 with the help of pin. Laser spot must coincide with the center of reticule.

Adjustment of the focus of laser beam

Aim at the target and watch in the eyepiece. Rotate laser screw (4) until you get minimum size of the laser spot on the target.

Otherwise adjust the size of the laser spot up to the minimum size with the help of adjusting screws, as shown in the picture 10.

7. Maintenance

1) Use handle for transportation (11) to take the instrument from the box. Never touch the lens to take it from the case;

2) Rotation of the alidade must be easy;

3) Avoid direct sunlight during operation;

4) To clean the lens rst use special soft brush. Then wipe it with cotton wool or cleaning napkin. After usage remove all dust and

dirt from the surface of the instrument and place it into the clean dry case;

5) Keep the instrument clean;

6) Put the instrument into the case to avoid damages during transportation; Keep case in the dry clean place;

7) Insert out the batteries if you are not going to use instrument for a long time;

8) Don’t leave the instrument without usage for a long time on the construction site. Vibration, dust, humidity can have negative

inuence upon instrument.
