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 refer-
ence 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 remov-
ing 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;
