1.The structure of the instrument is compact and ingenious. It affords easy portability and direct, rapid reading. The newest
form of construction at present is adopted in its designing, and it is stable and reliable.
2.This theodolite is equipped with automatic compensator of vertical circle index with V-shape long pendulum, which gives a
good performance in resisting high-frequency vibrations. This not only promotes surveying precision, but also, makes the
operation easy. It simplifies manipulation procedures, and raises working efficiency.

5. HOW TO USE THE INSTRUMENT
1. Positioning the tripod.
Place the tripod over the measuring point and set the three legs almost equidistant to it. The place of mounting should be as
level as possible. Turn the wing clamps on the legs clockwise. It will enable them to be properly extended. The pointed shoes on
the tips of the legs should pierce the surface of the ground somewhat so that the tripod is surely erected and reliable as
surveying work is being performed on it.
2. Mounting the instrument on the tripod.
Place the instrument carefully on the tripod and tighten the central screw properly.
3. Adjusting the level of the instrument.
Use the circular level and foot screws of tribrach to roughly adjust the level of the instrument and then use the tubular one to do
precision levelling.
Levelling with circular level: Turn the screws 1 and 2, as shown in figure 4A, so that the bubble moves to the central line of
the circular level, and then turn the screw 3, as shown in figure 4B, so that the bubble is exactly in the center of the level.

Levelling with the tubular level: Turn the alidade of theodolite first in order to make the tubular level parallel to the line
connecting the centers of any two foot screws (Fig. 5A), and at the same time, turn the two foot screws to enable the bubble to
position itself in the middle of the tubular level. Then turn the alidade 90° (Fig. 5B) and also turn the third foot screw to make the
bubble move to the middle of the level. Repeat the above described procedure several times so that the offset of the bubble
doesn't exceed the allowance for whatever position the alidade is turned.
4. Mounting the instrument properly over the measuring point.
Use an optical plummet to enable the center of the vertical axis of the theodolite to be directly over the plummet line of measuring
point. When the optical plummet is used, pull out its visual lens and turn it so that the measuring point is distinctly imaged on the
graduated plate. If the center of the measuring point is not in the center of the graduated plate, loosen the central screw of the
tripod. Then tighten the central screw of the tripod, and check the levelling of the instrument. Turn the alidade 180° and repeat
the above described procedure.
5. Illumination
Turning the position of the light reflection mirror (11) properly will result in a bright illumination of the graduated circle.

6. Angle measurement
1. Turn the telescope to the given point. Use the rough optical sighting device to aim at the
object.
Then rotate the eyepiece in the counter-clockwise direction until the clear image of reticule.
Turn the focussing sleeve of the telescope so that the object will be clearly imaged on the
graduated plate.
2. Fix the position of telescope with the help of horizontal and vertical (21) clamps.
Turn both horizontal and vertical micrometer screws (17 and 18) so that the telescope is
precisely aimed at the target to be measured. At this moment, move the eye left and right,
and then up and down. In doing so, no relative displacement should be detected between
the target image and the graduation marks on the graduated plate. This means that no
parallax exist.

7. Graduated circle reading.
After illuminating the graduated circle, adjust the reading eyepiece (4) so that the reading visual
field, as shown in Fig.6, can be seen distinctly. The symbols H and V indicate the readings of the
horizontal and the vertical circles respectively. There are 60 graduations to every division (1') on
the tape and so estimation readings up to 0,1. And the reading error 0,05-0,1 of the graduated
circle corresponds to 3"-6" angular sec. The system of readings of vertical angles starts from
the horizon 90°. Before making the reading on the vertical circle, it is necessary to turn the locking
knob (10) of the automatic compensator to enable the compensator index mechanism to be in a
free state. At this moment very distinct sound is audible. And only then you can take the readings
of the vertical circle.

6. ADJUSTING THE THEODOLITE
8. Stadia measurement.
There are two pairs of short hairs on the graduated plate of the telescope, i.e. stadia hairs. They are used to measure the
distance between the target to be measured and the measurement point of the instrument.
Assume the distance between the staff and the measuring point is D. The length cut by a pairs of the stadia hairs on the scale
is L and constants of the stadia are K and C which are 100 and 0 respectively. The distance measurement formula is following:
D=KL+C-100L
Formula of horizontal distance, taking into account a slope:
D=KLC*OS a, where a- a vertical angle of slope
Formula for calculation the exceeding between points:
H=0,5 kL siin2a +1-v, where l- height of theodolite, v- height of aiming at the staff.
9. Using the rotary circle mechanism.
Theodolites Prof X2 are equipped with a rotary circle knob (5). It enables the reading value of the horizontal graduated
circle to be placed in the direction of the target to be measured. To avoid errors, it is necessary to aim at the target, to press the
locking catch of the rotary knob (5) and press the knob (5) simultaneously. Then, rotating the knob (5) in the counter-clockwise
direction, set the necessary reading. After this procedure press the locking catch again to unlock the limb.
All instruments are adjusted and checked and then transported to users after careful packing. But nevertheless before usage it is
necessary to repeat the adjustment as the transportation and storing conditions may tend to engender the possibility of deviation
from correct positions adjusted originally.
Such adjustment should be done as follows:
1. Adjusting the tubular level of the alidade
Turn the alidade so as to enable the tubular level to be parallel with the line connecting the centers of any two of foot screws.

MEASUREMENT FOUNDATION
Turn the two screws in opposite directions equally so that the bubble will be in the middle of the level. Turn the alidade 90° and
with the third screw make the bubble in the middle of the level. Turn the alidade 90° again. If it's necessary, make the bubble in
the center again. Turn the alidade 180°. If the bubble is not in the middle, you should do further adjustment.
The foot screw on the half to which the bubble deviates should be turned so as to eliminate the offset value.
The other half can be corrected by turning the screw on the tubular level. For convenience, use the special pin.
2. Adjusting the circular level.
After adjusting the tubular level you should adjust the circular level. If the bubble of the circular level deviates from the center,
adjust it with three adjusting screws, which are under the level.
3. Adjusting the reticule of the telescope.
Focus the telescope at a plummet about 50 metres away. With micrometer screw, overlay the image of the top of the vertical
hair of telescope with the image of plummet of the hair. If they differ in more than 3 strokes, it's necessary to do the adjustment.
1. Screw the protective cap of the graduated plate of the telescope in the counter-clockwise direction and take it off. You see the
four adjusting screws on the frame.
2. Loosen the four adjusting screws with the help of screwdriver. Turn the frame of the graduated plate to enable the hair to be
vertical. Fix carefully new position of the frame tightening the screws. Repeat the adjustment.
4. Correcting the collimation axis error 2c
Place the theodolite at distance 100 metres from the target. Level the instrument and then check it.
1. Focus the telescope at the target in the position of the instrument “circle left” and take horizontal circle reading Л1.
2. Repeat the same focusing but in the position of the instrument “circle right” Take reading П1.
3. Loosen clamp finger of the support, turn theodolite 180° and then fix the clamp finger again.
4. Calculate the value of collimation axis error:
c=0,25[(Л1-П1±180°)=(Л2-П2±180°)]
