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.

H N

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.




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.

Laser plummet

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.

Depending on brightness and surfacethe size of the laser spot can vary. Ata distance of 1.5 m an average valueof 2.5 mm diameter must beestimated.

The maximum diameter of thecircular movement described by thecentre of the laser point should notexceed 3 mm at a distance of 1.5m.

Laser spot:Ø 2.5 mm / 1.5 m


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.

TC30

0z88

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.


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).

Reflectorless EDM, contd.

Throughout the adjustmentprocedure, keep the

telescope pointing to the target plate.

After each field adjustment,replace the plugs in the

adjustment ports to keep out dampand dirt.

Atmospheric correction

The distance displayed is correct onlyif the scale correction in ppm (mm/km) which has been enteredcorresponds to the atmosphericconditions prevailing at the time ofthe measurement.

The atmospheric correction includesadjustments for air pressure, airtemperature and relative humidity.

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.
