Free Station
The application "Free Station" is usedto determine the instrument positionfrom measurements to a minimum oftwo known points and a maximum offive known points.It supports measurements to pointsusing either distances and Hz- and V-angles (typical 2 point resection) orangles only (typical 3 point resection)or a combination of angles anddistances to different points.

The following measurementssequences to target points arepossible:1. Hz- and V-angles only2. Distance and Hz- and V-angle3. Hz- and V-angles to some point(s)
and Hz- and V-angle plus distanceto other point(s).
The final computed results areEasting, Northing and Height of thepresent instrument station, includingthe instruments Hz-circle orientation.Standard deviations and residuals foraccuracy assessments are providedadditionally.
The station coordinates andorientation can be finally set active tothe system.
Measurements and results (position,standard deviations and residuals)are always recorded to the internalmemory, provided the internalmemory is set as the Data Storagemedia.
All shown displays areexamples. It is possible that
local software versions are differentto the basic version.

Measuring facilities
Single face I or II or dual face I + IImeasurements are always possible.No specific point sequence orspecific face sequences are required.Any point can be measured with anyface at any time prior of starting thecomputation process, e.g. measurethe last point first - then the first point- and then the second point - etc�
Gross errors checks are made fordual face measurements to ensurethe same point(s) are sighted withthe other face.
Measurement restrictions:
� 2 face measurementsFor measurements in 2 faces, thereflector height and the refractioncoefficient must be kept the samefor both faces for the same targetpoint, although it is permissible tochange them between differenttarget points. An error messagewill be generated if the reflectorheight changes between face I andface II while measuring to thesame target point.
� Target points with 0.000 heightTarget points with 0.000 height arediscarded for height processing. Iftarget points have a valid height of0.000 m, use 0.001 m to enable itfor height processing.
If a target point is measuredseveral times in the same
telescope position the last validmeasurement is used forcomputation.

The computation processautomatically determines theprocessing method, e.g. 2 pointresection, 3 point resection withangles only, etc�)If more than the minimum requiredmeasurements are performed, theprocessing routine uses a leastsquares adjustment to determine theplan position and averagesorientation and heights.
1. The original averaged face I andface II measurements enter thecomputation process. In case ofmultiple measurements to thesame target point, only the lastmeasurement for each face enterthe computation process.
2. All measurements are treated withthe same accuracy, whether theseare measured in single or dualface.
Computation procedure
3. The final plan position (E, H) iscomputed from a least squaresadjustment, including standarddeviations and residuals for Hz-angle and horizontal distances.
4. The final height (H) is computedfrom averaged height differencesbased on the originalmeasurements.

The laser plummet is integrated intothe vertical axis of the instrument.Under normal circumstances settingof the laser plummet is notnecessary. If an adjustment isnecessary due to external influencesthe instrument has to be returned toany Leica service department.
Checking by turning theinstrument by 360°:1. Install the instrument on the tripod
approx. 1.5 m above ground andlevel up.
2. Switch on laser plummet and markthe centre of the red spot.
3. Turn instrument slowly by 360°and observe the red laser spot.
Inspecting the laser plummet shouldbe carried out on a bright, smoothand horizonal surface (e.g. a sheet ofpaper).
If the centre of the laser spot makesa clearly circular movement or if thecentre of the point is moving awaymore than 3 mm from the firstmarked point an adjustment ispossibly necessary. Call your nearestLeica service department.

Reflectorless EDM
The red laser beam used formeasuring without reflector isarranged coaxially with the line ofsight of the telescope, and emergesfrom the objective port. If theinstrument is well adjusted, the redmeasuring beam will coincide withthe visual line of sight. Externalinfluences such as shock or largetemperature fluctuations can displacethe red measuring beam relative tothe line of sight.
The direction of the beamshould be inspected before
precise measurement of distances isattempted, because an excessivedeviation of the laser beam from theline of sight can result in imprecisedistance measurements.

Inspection
A target plate is provided. Set it upbetween five and 20 metres awaywith the grey reflective side facing theinstrument. Move the telescope toface II. Switch on the red laser beamby activating the laser-point function.Use the telescope crosshair to alignthe instrument with the centre of thetarget plate, and then inspect theposition of the red laser spot on thetarget plate. Generally speaking thered spot cannot be seen through thetelescope, so look at the target platefrom just above the telescope or fromjust to the side of it.If the spot illuminates the cross, theachievable adjustment precision hasbeen reached; if it lies outside thelimits of the cross, the direction of thebeam needs to be adjusted.
If the spot on the more reflective sideof the plate is too bright (dazzling),use the white side instead to carryout the inspection.
121TC(R)303/305/307-3.5en Care and Storage
Adjusting the direction of the beam
Pull the two plugs out from theadjustment ports on the top side ofthe telescope housing.To correct the height of the beam,insert the screwdriver into the rearadjustment port and turn it clockwise(spot on target plate moves obliquelyupwards) or anticlockwise (spotmoves obliquely downwards).To correct the beam laterally, insertthe screwdriver into the frontadjustment port and turn it clockwise(spot moves to the right) oranticlockwise (spot moves to theleft).

If, for highest-precision distancemeasurements, the atmosphericcorrection should be determined withan accuracy of 1 ppm, the followingparameters must be redetermined:Air temperature to 1°C; air pressureto 3 millibars; relative humidity to20%.
The air humidity influences thedistance measurement if the climateis extremely hot and damp.
For high-precision measurements,the relative humidity must bemeasured and entered along with theair pressure and the temperature.

Reduction formulae
= displayed slope distance [m]D0 = uncorrected distance [m]ppm = scale correction [mm/km]mm = prism constant [mm]
= D0 · (1 + ppm · 10-6) + mm
= X + B · Y2
= horizontal distance [m]= height difference [m]
Y = · |sin ζ |X = · cos ζζ = vertical-circle reading
A = 1 - k / 2 R = 1.47 · 10-7 [m-1]
k = 0.13R = 6.37 · 106 m
B = 1 - k 2R = 6.83 · 10-8 [m-1]
The instrument calculates slopedistance, horizontal distance andheight difference in accordance withthe following formula. Earth curvatureand mean refraction coefficient (k =0.13) are taken into accountautomatically. The calculated hori-zontal distance relates to the stationheight, not to the reflector height.
