1. Application

The electronic theodolite adopts incrrmental digit angle measurement system. The resolution of horizontal angle reading and vertical angle reading is I" , 5" (0.2mgon, lmgon ). The angle precision is 2" , 5" (0.5mgon, lmgon ).

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 DCH range finder made in MATO, PDA and

EDM made in the other factory international. 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 fulfilled.

The electronic theodolite can be used for the control surveying, mine, railway, and irrigation etc projects surveys

Still capable of topographic surveys and general projects surveys.

Adjustment is required to make the line of sight of optical plummet telescope coincide with the vertical axis ( as otherwise the vertical axis will not be in the true vertical when the instrument is optically plumbed.)

Check a. Coincide the center point with the center mark of optical plummet telescope by adjusting optical plummet. b. Revolve the instrument 180

Adjustment a. Unscrew the adjustment section cover of the optical plummet telescope eyepiece, by revolving it in the counter clock-wise direction and take it off. This will expose four capstan adjustment screws which should be adjusted with the accessory adjusting pin to shift the center mark to the point. However, correct only 112 of the displacement in this manner.

5.1 Level the instrument

Level and center the instrument correctly to insure the best perfonnance.

C!) Place the tripod

First, put the tripod leg in the proper position and tighten the locking screws.

@ Attaching the instrument to the tripod head

Place the instrument carefully on the tripod head, and move the instrument slowly by loosening adjusting screw. Align the plumb bob with the point on the ground

When aligned, tighten the adjusting screw.

® Initial rough leveling the instrument with circular level

( 1 )

Use leveling screws 1,2 to move the bubble of the circular level until the bubble of the circular level until the bubble is now located on a line perpendicular to a line running through the centers of the two leveling screws being adjusted.

Adjustment reticle retaining screws eyepiece a. Unscrew the cross-hair adjustment section cover by revolving it in the counter-clockwise direction. This will expose four eyepiece section attachment screws. b. 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. c. Check if there is displacement in horizontal direction while point A travelling along vertical cross-hair. If not, check is concluded.

12.3 Check and adjust vertical cross-hair

Adjustment is required if the vertical cross-hair is not in a phine perpendicUlar to the horizontal axis of the telescope.(Since it must be possible to use any point on the hair for measuring horizontal angles.)

Check a. Set the instrument on the tripod and carefully level it. b. Sight the cross-hair on a well-defined 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 fig.l), 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 fig.2) , adjustment is required in the reticule plate.

@Further leveling the instrument with plate level

(1) Loosen horizontal motion clamp and revolve the instrument. By adjusting leveling screws l,2 , the plate level vial is parallel to a line running through the centers of two leveling screws, and place the bubble in the center of the level vial.

(2) Next, revolve the instrument 90° (lOOg) around its vertical axis and use the remaining screw 3 to center the level bubble once more.

(3)

Repeat the above procedure for each 90 revolution of the .instrument and check whether the level bubble is correctly centered for all points.

@Centering the instrument with optical plummet

Adjust the eyepiece of the optical plummet telescope to the user's eyesight. Move the instrument by loosening

12.2 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)

However, correct only one-half of the displacement by this method. b. Correct the remaining 112 amount of the bubble displacement with the leveling screws. c. Revolve the instrument 180 0 or 200g around the vertical axis once more and check bubble movement if the bubble is still displaced, then repeat the adjustment. adjustment screws

Pointers on 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 sufficiently upon completion of adjustments. e. Always repeat checking operations after adjustments are made in order to verify results.
