Centering and Leveling with Optical Plummet
• Extend the tripod legs to a suitable working height with equal length legs. Spread the
tripod legs and make the tripod head as level as possible while at the same time placing the center of the tripod head directly over the ground point. Press the leg feet firmly into the ground and make sure the tripod legs are locked.
• Set the instrument carefully on the center of the tripod head orientating the leveling
screws centered with each tripod leg. Attach the instrument to the tripod. Make sure the center mark is visible on all three leveling screws (this ensures a complete leveling range).
• Adjust the Optical Plummet Eyepiece to focus the crosshairs. Adjust the Optical
Plummet telescope focus to see the ground clearly. If you can not see the ground point while looking through the optical plummet, carefully lift two of the tripods legs, then pivot on the third leg, carefully moving the tripod until the ground point is within one inch of the reticule. Press the two tripod feet back into the ground and recheck the optical plummet alignment. Repeat if necessary until the ground point can be seen in the optical plummet field. Complete the alignment by turning the leveling screws (you will not be level but you are pointed correctly).

Centering and Leveling with Optical Plummet
• Now center the instruments Circular Vial by carefully extending or shortening the tripod
leg closest to the bubble. Caution: Use only two legs. Repeat until alignment is within 6 mm (¼ inch) or better.
• Next use the Tubular Vial to accurately level the instrument. Unlock and turn the
instrument so that the tubular vial is parallel to BC, any two leveling screws. Note the direction to turn the leveling screws in the graphic. When turning the two screws, adjust them equally. The bubble will move in the direction that your left thumb turns. To move the bubble to the right, turn the B leveling screw in and simultaneously turn the C leveling screw in. To move the bubble left, move both screws out simultaneously. Once centered turn the instrument 90˚ over A leveling screw and turn screw A in or out until bubble is centered. Go back to the first position BC, and repeat until the bubble is centered in both positions. Then from position BC turn 180˚ to check the adjustment. If the bubble stays centered or within ¼ division, you are leveled.
• Now, check the ground point centering. If you are not directly on the point, carefully
loosen the tripod fastener and move the instrument on the tripod head in an x - y direction. Do not rotate the instrument. Recheck leveling and repeat until instruments is level and over the ground point at the same time. With practice, this becomes easier.

Installation and Removal of the Base
Base Removal
• Turn the screw on the Tribrach Locking Lever outward using a flat screw driver to its stop.
• Turn Tribrach Locking Lever 180° counterclockwise. Holding the base with one hand,
take the main body off the base.
Base Installation
• Turn the Tribrach Locking Knob counterclockwise until it reaches the position limit.
Align the positioning block on the main body of the instrument to the notch on the base. Install the main body onto the base .
• Turn the Tribrach Locking Lever clockwise until it reaches the position limit so that the
‘v’ mark points downward. Turn the locking screw inward until it hits its stop.
INSPECTION
Tubular vial
• Attach the instrument to a tripod and rough level. Position the tubular vial parallel to a
line connecting any two of the three leveling screws on the base. Adjust the two leveling screws so that the tubular bubble is centered.
• Turn the instrument 180° and check if the bubble remains at the center.
• If the bubble remains at the center, no adjustment is required. Otherwise, perform
adjustments as follows:
• Using the bubble adjustment screws, move the bubble towards the tube center for half of
the error
• Turn the leveling screw to correct the other half of the error so that the bubble is
centered.
• Rotate the instrument 180 degrees and check if the bubble remains centered. If the
bubble is centered, the adjustment is complete. If not, repeat the steps until the bubble is centered when the instrument is at any position.
Circle vial
After making sure that the tubular vial is correctly adjusted, check the circular level. If the bubble is centered, no adjustment is required. Otherwise, adjust the three adjustment screws with a needle to center the bubble.
Optical Plummet
• Attach the theodolite to a tripod (no leveling is required).
• Place a target under the instrument.
• Focus the image of the target then adjust the leveling screws so that the target is centered
in the reticule.
• Turn the instrument 180°.
• If the target remains at the center of the reticule, no adjustment is required. Otherwise,
adjust as follows.
• Unscrew the optical plummet protective cover ring
• Using the adjustment screws for the reticule, reduce the off—center distance by half.
Note: use the needle (as shown below).
• Repeat the above steps until the target coincides with the center.
Perpendicularity of Vertical Crosshair of Reticule of Telescope
• Attach the instrument on a tripod and precisely level
• Place a target point, A, 50M away from instrument.
• Aim the telescope at point A. Move the telescope using the vertical fine movement. If
point A moves along the vertical hair of the reticule, no adjustment is required.
Perform the following adjustment if the point A strays from the vertical crosshair:
• Remove the protective cover of the reticule and slightly loosen the four adjusting screws.
Turn the assembly so that point A coincides with the vertical hair, retighten the four adjusting screws.
Repeat the above steps until there is no error.

Collimation Error
• Attach the instrument on a tripod and precisely level.
• Aim at point A in the distance with the normal, direct position of telescope. Record the
reading of the horizontal angle - HR-DIRECT. Next using the reverse position of the telescope, take the reading of the horizontal angle - HR-REVERSE, then:
Collimation Error C = (HR-Direct -— HR-Reverse ± 180°)/2
If C <10”, no adjustment is required. If C >10”, the following adjustment is required:
Adjust the horizontal fine motion in the reverse position of the telescope so that the reverse reading HR-Rev = HR-Rev + C.
Remove the protective cover of the reticule of the telescope and adjust both the left and right adjusting screws so that the vertical hair of the reticule coincides with object A.
Repeat the steps until acceptable condition is reached.
Index Error of Vertical Circle
• Attach the instrument on a tripod and precisely level.
• Aim at any object, point P, in the normal position and take the reading of vertical angle -
V-Direct.
• Turn the telescope to the reverse position and aim it at point P again. Take the reading of
other vertical angle - V-Rev.
• If (V-Direct + V-Rev) - 360°= ≤15”, no adjustment is required. Otherwise, perform
adjustment as follows:
Press and hold [R/L] + [HOLD] buttons while pressing [ON/OFF] button. Release [ON/OFF] button when full character display appears and then release [R/L] + [HOLD] buttons when four beeps are heard.
Swing the telescope near horizontal with the instrument in the normal position. Allow the vertical angle to reset after it crosses zero. Aim the telescope in the normal position at object P and press [0SET] to confirm.
Aim the telescope in the reverse position at object P and press [0SET] to confirm. With this, the compensation of index error is completed.
