(3) Firmly press the tripod ferrules into the ground. (4) Level the top surface of the tripod head. (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.
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.
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.
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.
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).
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.
6. Sighting Center crosshairs of the reticle WARNING ■ Never look at the sun through the telescope. II PREPARATION “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. 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.

(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. 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.
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°.
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.
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...
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.
