28 4. Prepar ation for Surve ying 4.1 Setting up the instrument A djust the tripod legs so that a height suitable for surveying is obtained when the instrument is set on the tripod. A Set the tripod and fix the metal shoe firmly into the ground so that the tripod head is as level as possible and centered abo ve the station point.
29 4.2 Lev eling with the Circular level Aft er [4.1 Setting up the instrument] is completed, instrument must be leveled using the circular vial. By rotating any two lev eling screws, position the bubble in the center of the vial (See A.) ( T o adjust the screws at the same time, turn them in opposite directions.
30 4.3 Lev eling with the Plate level Aft er [4.2 Leveling with the circular vial] is completed , instrument must be leveled with plate vial. Place the plate vial in parallel with a line joining any tw o of the leveling screws.
31 4.4 Cent ering with the optical plummet Aft er [4.3 Leveling with the plate vials] is completed , the instrument must be centered abov e the station point. Fo cus the optical plummet reticule by rotating the optical plummet eyepiece knob. Fo cus the station point by rotating the optical plummet focusing knob.
32 4.5 Ey epiece adjustment Aft er [4.4 Centering with the optical plummet] completed , focus the t elescope eyepiece on the t elescope reticule. Remove the telesc ope lens cap. P oint the telesc ope at a bright object. Rotate the eyepiece complet ely counterclockwise.
33 4.6 Object sighting Aft er [4.5 Eyepiece adjustment] is completed , sight the object. Lo osen the telescope clamp screw and horizontal clamp screw . P oint the telesc ope at the object using the collimator sight. Tighten the telescope clamp screw and horizontal clamp scr ew .
34 5. Measurement 5.1 Horizontal angle measurement (righ t) Lev el the instrument, and after power on set the vertical angle 0 point. Sight the first object using the horizontal clamp and tangent screw as w ell as the telescope clamp and tangent screw .
35 5.2 Horizontal angle measurement (left) Lev el the instrument, and after the power on set the vertical angle 0 point. Sight the first object using the horizontal clamp and tangent screw as w ell as screw as well as the telesc ope clamp and tangent screw .
36 5.3 Ve rtical angle measurement Lev el the instrument, turn the power on and set the vertical angle 0 point. Sight the object A using the horizontal clamp and tangent screws as well as the telescope clamp and tangent screws. Read the displayed v alue ( ).
37 6. Inspection and Adjustment 6.1 Instructions on inspec tion and adjustment • Inspection and adjustment should be done after setting the instrument on a tripod or on an adjustment stand. • Inspection should be done sequentially from [6.2 Plate vial] to [6.
38 A djustment Ce nter the plate vial bubble. Rotate the instrument 180°, move the bubble half way back to the center by operating a lev eling screw which is located parallel with the plate vial. Rotate the vial adjusting screw with the adjusting pin and position the bubble in the center .
39 6.3 Perpendicularity of circular vial to v er tical axis Inspection C onfirm if the bubble of the circular vial is in the center after the inspection and adjustment of [6.2 Plate vial]. No adjustment is necessary if the bubble of the circular vial is in the center but if not, the following adjustment is required.
40 6.4 Inclination of reticule gradua tions Inspection S et an object point A on the line of sight through the telescope. Move point A to the edge of the field of view b y adjusting the t elescope tangent screw (point A ’). No adjustment is necessary if point A moves along the vertical line of the reticule.
41 6.5 Perpendicularity of line of sight to horiz ontal axis Inspection S et an object (point A) at a distance of 30 to 50m away from the instrument and sight it through the telescope. Lo osen the telescope clamp screw and reverse the telesc ope around the horizontal axis.
42 6.6 Difference of the v er tical angle Inspection S et the vertical angle in Zenith 0° mode Sight an object (Point P) with the telescope and read the v ertical angle ( V correct). Reverse the telescope and rotat e the alidade. Sight point P again in the reverse position and r ead the vertical angle ( V reverse).
43 6.7 Optical plummet Inspection Place a piece of white paper , with a cross drawn on it, directly under the instrument. Lo ok through the optical plummet, and move the paper so that the intersecting point of the cross comes to the center of the field of view .
44 7. Optional Acc essories 7.1 Diagonal Ey epiece (SB14) T he Diagonal eyepiece can be attached to the t elescope for con venience in observing the zenith or when in confined spaces. <Installation> Tu rn the telescope eyepiece ring c ounterclockwise to remove the eyepiece.
