Application
DigiTeo electronic theodolite adopts incremental digit angle measurement system. The resolution of horizontal angle reading and verti-
cal angle reading is 1″, 5″(0.2mgon, 1mgon ). The angle precision is 2″, 5″(0.5mgon, 1mgon ).
Meanwhile microcomputer techniques adopted in the instrument realizes automatic calculation, storage, and display. The instrument
can display the readings of horizontal angle and vertical angle simultaneously. It can use with the PDA and EDM . Then you can get the
electric speed measurement instrument. It can display, put down the angle, distance and coordinate data. It can correct the instrument
error. Many measuring modes as angle, slope etc can be fullled. DigiTeo electronic theodolite is used for the control surveying, mine,
railway, and irrigation etc projects surveys. Still capable of topographic surveys and general projects surveys.

Check and adjustment
a. Adjust the eyepiece of the telescope properly prior
to any checking operation which involves sighting
through the telescope. Remember to focus properly,
with parallax completely eliminated.
b. Carry out the adjustment in the order listed, as
the adjustments are dependent one upon another.
Adjustments carried out in the wrong sequence may
even nullify previous adjustments
c. Conclude adjustments by tightening the adjustment
screws securely ( but do not tightening them more than
necessary, as you may strip the threads, twist off the
screw necessary, as you may strip the threads, twist off
the screw or place undue stress on the parts.)
d. The attachment screws must also be tightened suf-
ciently upon completion of adjustments.
e. Always repeat checking operations after adjustments
are made in order to verify results.
1. Check and adjust the plate level.
Check:
a. Place the plate level parallel to aline running through
the centers of two leveling screws(e.g. A, B). Use these
two screws to place the bubble in the center of the plate
level vial.
b. Next, revolve the instrument 180° or 200gon
around the vertical axis and check bubble movement
of the plate level. If the bubble has been displaced,
then proceed with the following adjustment.
Adjustment:
a. Adjust the level adjustment capstan screw with the
accessory adjusting pin and return the bubble towards
thecenter oftheplatelevelvial.However, correctonly
one-half of the displacement by this method.
b. Correct the remaining 1/2 amount of the bubble
displacement with the leveling screws.
c. Revolve the instrument 180°or 200gon around the vertical axis once more and
check bubble movement if the bubble is still displaced, then repeat the adjustment.
2. Check and adjust vertical cross-hair.
Check: Carefully level the instrument with the plate level. If the bubble of
the circular level is centered properly at this time, adjustment is not required.
Otherwise, proceed with the following adjustment.
Adjustment: Shift the bubble to the center of the level by adjusting three
capstan adjustment screws on the bottom surface of the circular level, with
the accessory adjusting pin.(see diagram)

Adjustment:
Unscrew the cross-hair adjustment section cover by
revolving it in the counter-clockwise direction. This
will expose four eyepiece section attachment screws.
a. Loosen all four attachment screws slightly with
the accessory screw-driver. (while taking note of the
number of the revolutions.) Make vertical cross-hair
coincide with A by turning eyepiece and tighten the
four attachment screws.
b. Check if there is displacement in horizontal direction while point A travel-
ling along vertical cross-hair. If not, check is concluded.
4. Collimation of the instrument
Collimation is required to make the line of sight of the telescope per-
pendicular to the horizontal axis of the instrument.
Check:
a. Set the instrument up with clear sights of abort 50 to 60 meters of both
sides of the instrument.
b. Sight pointA at approximately 50 meter distance.
c. Loosen the vertical tangent screw only and plunge the telescope 180 °
around the horizontal axis so that the telescope is pointed in the opposite
direction.
d. Sight point B, at equal distance as point A.
e. Loosen the horizontal motion clamp and tangent screw and revolve the
instrument 180°or 200gon. Fix a sight on point A once more and tighten
the motion clamp and screw.
3. Check and adjust vertical cross-hair
Adjustment is required if the vertical cross-hair is not
in a plane perpendicular to the horizontal axis of the
telescope.
Check:
a. Set the instrument on the tripod and carefully level it.
b. Sight the cross-hair on a well-dened point A on the
wall at a distance of at least 50 meters. (160ft )
c. Next swing the telescope and check whether the
point travels along the length of the vertical cross
hair.
d. If the point appears to move continuously on the
vertical hair (see g.1), the vertical cross-hair lies in
a plane perpendicular to the horizontal axis.(adjustment
is not required.)
e. However if the point appears to be displayed from
the vertical cross-hair (see g.2) , adjustment is
required in the reticule plate.

f. Loosen the vertical motion clamp and tangent screw and plunge the instrument 180 ° or 200gon and x a sight on point C, which
should coincide with the previous point B.
g. If point B and C do not coincide, adjust in the
following order:
Adjustment:
a. Unscrew the cross-hair adjustment section cover.
b. Find point D at a point between points C. B, which should be equal to 1/4 the distance between points B and C, and measured from
point C. This is because the parent error of BC is four times of the real error since the lescope has been reversed twice during checking
operation.
c. Shift the vertical cross-hair line and coincide it with point D, by revolving the left and right capstan adjustment rews. Upon complet-
ing the adjustment, repeat the checking operation once more. If point B and C coincide, further adjustment is not required. Otherwise,
repeat the adjustment.
