■ The Electrical Digital Theodolite is a precision instrument.

Do not subject it to shocks or excessive vibration.

■ Do not loosen or remove any screws unless specifically required.

■ Do not carry the instrument mounted on the tripod on your shoulder.

■ Avoid prolonged exposure to the sun or the heat of a closed vehicle. Failure to do so may adversely affect the efficiency of the instrument.

■ If the instrument has been used in wet conditions, immediately wipe off any moisture and dry it completely before replacing it in its carrying case. Exposure to moisture or/and dust may cause severe instrument damage.

■ Sudden changes in temperature, such as caused by bringing the instrument into a warm room from the cold outdoors, can cause internal condensation. This may result in reduced measuring accuracy or electrical system failure. Should this occur, leave the instrument in a warm location with the carrying case closed until the temperature of the instrument returns to room temperature.

■ Avoid storing the instrument in hot, humid conditions. The battery pack should be stored in dry conditions and a temperature of less than 30°C. Higher temperatures and excessive humidity may result in growth of mold on the lenses and deterioration of the electronic components, leading to instrument failure.

■ Battery operating hours tends to be reduced by continuous use at extremely low temperatures.

MAINTENANCE

Read This Section Before Use!

■ Operation in extremely low, ambient temperatures can cause delays in LCD operation.

■ Always be sure to check the battery capacity before use.

■ Remove the battery whenever the instrument is not to be used for an extended period of time.

■ When storing the instrument in areas subject to extremely low temperatures, leave the carrying case open.

■ Do not overtighten any of the clamp screws.

■ When adjusting the vertical and horizontal tangent screws or leveling screws, fix them as close as possible to the center position, as indicated by the lines on the screws.

Always be sure to finish the tangential adjustment with a clockwise rotation of the tangent screw.

■ If you do not intend to remove the leveling base from the instrument for an extended period, lock the leveling base clamp knob and tighten its safety screw.

■ Do not use organic solvents (such as ether or paint thinner) to clean the non-metallic parts such as the keyboard, and the painted or printed surfaces. Organic solvents will discolor the surfaces or remove the printed characters.

CAUTION

■ Be careful in handling or carrying the tripod, as the ferrule is very sharp and may cause injury to yourself or others.

■ Before setting up the tripod, check below to make sure no one’s hands or feet are in the way. Failure to do so may result in injury if hands or feet should be pierced by the legs of the tripod.

■ Fasten firmly the thumbscrews of the tripod legs before mounting the instrument. Failure to do so may cause the tripod to collapse, resulting personal injury or instrument damage.

■ Secure the instrument on the tripod by tightly fastening the clamp screw of the tripod. Failure to do so may cause the instrument to fall, resulting in personal injury or instrument damage.

16

(1) Open the tripod legs sufficiently enough for the instrument to be stable.

(2) Assure that the station point is located directly beneath the center hole in the tripod head.

(3) Firmly press the tripod ferrules into the ground.

(4) Level the top surface of the tripod head.

•

A precise leveling is necessary when the plumb bob is used for the next section, “centering”.

II

(5) Fasten firmly the clamp screws on the tripod legs.

(6) Place the instrument on the tripod head. Insert the instrument clamp screw on the tripod into the center hole of the instrument’s base plate and tighten.

NOTE •

Do not carry the instrument mounted on the tripod on your shoulder.

17

4. Centering

“Centering” refers to the precise alignment of the instrument’s central axis over the station point. This can be accomplished in two ways, through the use of a plumb bob, or the optical plummet.

1) Using Plumb Bob

For the models with detachable leveling base

(1) Place the instrument on the tripod head. Insert the instrument clamp screw into the center hole of the instrument’s base plate and tighten.

(2) Hang the plumb line on the hook of the instrument clamp screw.

Adjust the length of the plumb line so that the tip of the plumb bob is approximately level with the station point.

(3) Slightly loosen the instrument clamp screw. Supporting the outer side of the leveling base with both hands, carefully slide the instrument on the tripod head until the tip of the plumb bob coincides with the center of the station point.

•

Confirm precise alignment by viewing from two directions at right angles to each other.

18

For the model with centering leveling base

(1) Hang a hook for plumb bob line on the V-shaped metal bracket inside of the center of the instrument’s base plate.

(2) Pass the hook for plumb bob line through the hole of the instrument clamp screw. Place the instrument on the tripod head.

(3) Insert the instrument clamp screw into the center hole of the instrument’s base plate and tighten.

(4) Hang the plumb line on the hook of the instrument clamp screw.

Adjust the length of the plumb line so that the tip of the plumb bob is approximately level with the station point.

(5) Slightly loosen the instrument clamp screw. Supporting the outer side of the leveling base with both hands, carefully slide the instrument on the tripod head until the tip of the plumb bob approximates the center of station point (±10mm). Tighten the instrument clamp screw.

(6) Loosen the centering clamp and slide the instrument so that the tip of the plumb bob coincides with the center of the station point.

19

2) Using Optical Plummet

•

Carry out the “CHECKING AND ADJUSTMENT of Optical Plummet” (p.41) when the centering operation is performed at a position higher than the station point.

•

For high accuracy, carry out the “CHECKING AND ADJUSTMENT of

Optical Plummet” (p.41) before the centering operation.

For the models with detachable leveling base

(1) Place the instrument on the tripod head. Insert the instrument clamp screw into the center hole of the instrument’s base plate and tighten.

Nikon

Optical plummet

(2) Looking through the optical plummet, align the station point image with the center mark of the reticle by turning the leveling screws.

(3) While supporting the tripod head with one hand, loosen the tripod leg clamps and adjust the length of each leg to center the air bubble in the circular level. Then tighten the tripod leg clamps.

(4) Using the plate level, proceed to the leveling procedures described in the next section, “Leveling”.

(5) Looking through the optical plummet, check if the station point image is still centered in the reticle mark .

(6) If a slight displacement is detected, loosen the instrument clamp screw and adjust the position by moving the instrument laterally (not rotationally) on the tripod head. If the displacement is large, repeat

Steps from (2).

20

For the model with centering leveling base

(1) ~ (5) Follow the procedures (1) through (5) described above.

(6) If a slight displacement is detected, loosen the centering clamp and slide the instrument so that the station point image is centered in the reticle mark . If the displacement is large, repeat the above procedures (2) through (5).

21

5. Leveling

“Leveling” refers to the precise vertical alignment of the instrument’s vertical axis. The procedure for leveling by means of the plate level is described below.

(1) Loosen the upper plate clamp. Rotate the alidade so that the plate level comes to the position parallel with any two of the leveling screws (B and C in Figure [ 1 ]).

(2) Using these two screws, move the bubble to the center of the level.

(3) Rotate the alidade approximately 90° and again move the bubble to the center of the level by turning the leveling screw A, as shown in

Figure [ 2 ].

(4) Repeat Steps (1) through (3) to center the bubble in both Figures [ 1 ] and [ 2 ].

(5) Furthermore, rotate the alidade 180°. If the bubble in the plate level remains centered, leveling is complete.

(6) If the bubble moves off center, refer to p.39 “CHECKING AND

ADJUSTMENT of Plate Level” and adjust the plate level.

6. Sighting

“Sighting” refers to the aiming of the telescope at the target, bringing the target image into focus, and aligning it with the center crosshairs of the reticle.

WARNING

Center crosshairs of the reticle

■ Never look at the sun through the telescope. Doing so may cause the loss of your eyesight.

Notes on sighting are as follows:

• Diopter Adjustment

Direct the telescope towards a blank area, such as the sky or a piece of paper. Looking through the eyepiece, rotate the diopter ring to bring the reticle crosshairs into sharp focus.

• Elimination of Parallax

Rotate the focusing ring to bring the target image into focus on the reticle crosshairs. Move your eye vertically and laterally to see if the target image moves in relation to the reticle crosshairs. If the target image does not move, there is no parallax. If it moves, rotate the telescope focusing ring to eliminate the parallax.

V. CHECKING AND ADJUSTMENT

1. Plate Level

(Making the axis of the level vial at right angle to the vertical axis of the instrument)

1) Checking

(1) Set up the instrument on the tripod and follow the leveling procedures described on p.22, Chapter II-5.

(2) Rotate the alidade 180°.

(3) Check to see if the bubble remains in the center of the vial. If a displacement is detected it should be adjusted. Refer to the following adjustment procedure.

2) Adjustment

(1) Using the adjusting pin supplied, rotate the plate level's adjustment screw to move the bubble to eliminate half of the displacement detected.

(2) Take up the remaining displacement with leveling screw

A (refer to Figure on p.22), centering the bubble.

(3) Recheck, and repeat if necessary.

Nikon

V

39

2. Circular Level

After confirming the plate level is in adjustment, check for any displacement of the bubble's centering in the circular level. If it is out of adjustment, use the adjusting pin to manipulate the three adjustment screws, centering the bubble.

40

3. Optical Plummet

(Aligning the optical axis of the plummet with the instrument’s vertical axis.)

1) Checking

(1) Place the instrument on the tripod (no leveling necessary).

(2) Place a thick sheet of paper marked with an “

×

” on the ground directly underneath the instrument.

(3) Looking through the optical plummet, adjust the leveling screws to move the image of the “

×

” mark to the center of the reticle’s marking. (Refer to the Fig. [ 1 ] below.)

(4) Rotate the upper plate 180°.

(5) If the “

×

” mark remains centered in the reticle, no adjustment will be necessary. If any displacement is detected (Refer to the Fig. [ 2 ] below.), proceed to the following adjustment procedure.

Nikon

[ 1 ]

41

2) Adjustment

(1) Using the supplied hexagonal wrench, turn the adjustment screws to move the “

×

” mark exactly halfway to the center of the reticle mark, as indicated by Point P in the Fig. [ 2 ] above.

(2) Repeat Steps (3) ~ (5) of the checking procedure.

42

4. Vertical Circle Zero Point Error

1) Checking

(1) Set-up the instrument on the tripod and perform leveling.

(2) With the telescope in the face-1 position, aim at an arbitrary Target P positioned within ±10°/±11G from the horizontal plane, and take a reading of the vertical angle...VR

(3) Reverse the telescope to the face-2 position and take another reading of target P’s vertical angle...VL

(4) If VR + VL = 360°/400G when the zenith angle is set to 0°, or if VR +

VL = 180°/200G (or 540°/600G) when the horizontal angle is set to 0°, no adjustment will be necessary. Otherwise, refer to the following adjustment procedure.

Vertical error (2·e) corresponds to the above angles (360°, 180°, &

540° or 400G, 200G, & 600G), and is referred to as the vertical constant. The vertical constant is compensated for by doubling the zero point error (e) in the following procedure. Note that compass scale error (2·e) is not related to the vertical constant. Therefore, take a reading using either the zenith 0° or horizontal 0°, and check for error.

V

43

2) Adjustment

Before measurement, confirm the orientation of the vertical angle 0° in the initial setting mode.

(1) While depressing the [

] key, turn ON the power switch.

The entire display lights up and the current vertical constant value is displayed.

(2) Tilt the telescope across horizontal position on face-1 to reset the vertical angle.

Vertical angle “VR” appears on the upper line of the LCD.

(3) While in the face-1 position, sight an arbitrary Target P, located within ±10° of the horizontal plane.

VR becomes the vertical angle of

Target P.

(4) Depress the [HOLD] key to save reading VR in memory.

The saved VR reading is displayed on the upper line of the LCD, while VL is displayed on the lower line.

(5) Rotate the telescope to the face-2 position and sight the Target P again.

The target P’s vertical angle is displayed as on the lower line.

(6) Depress the [HOLD] key to save reading VL in memory.

The vertical constant is displayed one second after both face-1 and face-2 vertical angles are input.

AC: 0°01´20"

(7) Depress the [HOLD] key.

The vertical angle compensation is

TILT TELESCOPE

HA: 0°00´00" calculated as half the vertical constant and saved in the memory.

The LCD reverts to the start-up display.

■■■

Other key entries besides the [HOLD] key are ignored during this operation.

To cancel the vertical angle compensation input while in progress, turn

OFF the power.

During adjustment, if the

AC: OVER automatic vertical constant (AC) exceeds ±6', a buzzer sounds for 1 second, the “OVER” warning will appear on the display, and operation returns to Step (2).

The newly corrected constant will remain stored in memory even after the power is switched OFF. All subsequent vertical angle measurements will be corrected by the new AC.
