EltaR 3 Safety Notes

Risks in Use

Instruments and original accessories from Carl Zeisshave to be used only for the intended purpose.Read the manual carefully before the first use andkeep it with the instrument so that it will be readyto hand at any time. Be sure to comply with the

safety notes.

GAttention !Don t make any changes or repairs on theinstrument and accessories. This is allowedonly to the manufacturer or to specialist staffauthorised by the same.

Only the service team or authorisedspecialist staff are allowed to open the

instrument and accessories.Do not point the telescope directly at thesun.

Do not use the instrument and accessoriesin rooms with danger of explosion.

Use the instrument only within theoperative ranges and conditions defined inthe chapter of technical data.

Do not operate the battery charger inhumid or wet conditions (risk of electricalshock). Make sure the voltage setting is

identical on the battery charger and voltagesource. Do not use instruments while they arewet.


22/192

2-9


GAttention !Take the necessary precautions at yourmeasuring site in the field, note the relevanttraffic rules.

Check that the instrument has beencorrectly set up and the accessories areproperly secured.

Limit the time of working when it is raining,cover the instrument with the protectivehood during breaks.

After taking the instrument out of the case,fix it immediately to the tripod with theretaining screw. Do never leave it unfastenedon the tripod plate. After loosening theretaining screw again, put the instrumentimmediately back into the case.

Prior to starting operation, allow sufficienttime for the instrument to adjust to theambient temperature.

Tread the tripod legs sufficiently down inthe ground in order to keep the instrument instable position and to avoid its turning over incase of wind pressure.

Check your instrument at regular intervals inorder to avoid faulty measurements,especially after it has been subjected to shockor heavy punishment.

Remove the battery in case of beingdischarged or for a longer stop period of theinstrument. Recharge the batteries with theLG 20.

Properly dispose of the batteries andequipment taking into account the applicablenational regulations.


23/192

Attention

GAttention !The mains cable and plugs of accessories have to be

in perfect condition.When working with the tachymeter rod near toelectrical installations (for example electric railways,aerial lines, transmitting stations and others), there isacute danger to life, independent of the rod material.Inform in these cases the relevant and authorisedsecurity offices and follow their instructions. Keepsufficient distance to the electrical installations.

Avoid surveying during thunderstorms because oflightning danger.

First Steps 1 Before Measurement

Set-Up and Coarse Centring

In order to guarantee the stability of measurementwe recommend the use of aZeiss S27Tripod.

Set-up:Extend the tripod legs (1) to a comfortable heightof observation and fix them using the tripodlocking screws (2). Screw the instrument centrallyto the tripod head plate (3). The tribrach screws (4)should be in mid-position.

Coarse Centring:Set up the tripod roughly above the station point(ground mark), the tripod head plate (3) should beapproximately horizontal.

Centre the circular mark of the optical plummet (5)above the ground mark using the tribrach screws(4).

To focus the circle: Turn the eyepiece.

To focus the ground mark: Draw out or push in theeyepiece of the optical plummet.

Levelling and Fine Centring

Coarse Levelling:

Level the circular bubble (6) by adjusting the lengthof the tripod legs (1).

26/192

3-3


Precision Levelling:

Align the control unit parallel with the imaginaryconnecting line between two tribrach screws. Levelthe instrument by turning the tribrach screws a)and b) in opposite directions. Turn the instrumentby 100 gon in Hz and level instrument withtribrach screw c).For checking, turn the instrumentround the vertical axis. After that, check theresidual inclination by turning the instrument inboth diametral positions of (1) and (2). Take themean of deviation from center point of level andadjust, if necessary.

Precision Centring:Shift the tribrach on the tripod head plate until theimage of the ground mark is in the centre of thecircular mark of the optical plummet; repeat thelevelling various times if necessary.

Telescope Focusing

Focusing the Crosslines:Sight a bright, evenly coloured surface and turn thetelescope eyepiece until the line pattern is sharplydefined.

Focusing the target point:Turn the telescope focusing control until the targetpoint is sharply defined.

GAttention !

Sighting of the sun or strong light sources must byall means be avoided. This may cause irreparabledamage to your eyes.

FTip

Check the telescope parallax: If you move your headslightly whilst looking through the eyepiece, there mustbe no relative movement between the crosslines and thetarget; otherwise, refocus the crosslines as above.

Principles of Input

Additionally to the setting of predefinitions - asdescribed further down in this chapter - you willhave to enter data continually during themeasuring process.

These entries are

the constantly changing instrument, stationand reflector heights and

coordinates of stations or other knownbacksight points.

The manual input of coordinates is described inChapter6 Data Management.

If available, it is useful to transfer the values directlyfrom a PC instead of entering them manually.

Input of Reflector, Trunnion Axis and Station Heights

on display page 1 only:

The input of the values ofreflector height (th),instrument height (ih) andstation height (Zs) allowsyou to measure with

absolute heights already inthe initial menu. If thesevalues have not beenentered, only relative heightdifferences will appear inthe display (memory).

FTip

At this point, it would be convenient to usethe program of chapter 4.4CoordinatesStationing in Elevation. The station height is

determined by measuring to another visiblebacksight point.

Principles of Distance Measurements

The intensity of the receiving signal can be assessedwith the bar graph. The more to the right the starsare presented, the better is the returning signal.

The distance measurement can be cancelled withthe softkey ESC.

The slope distances and derived values arecorrected with regard to the influences of earthcurvature / refraction. Additionally, a correction ofatmospheric influences (temperature and pressure)is applied.

The correction is zero with T = 20C andP = 944 hPa.

The measuring mode can also be changed duringthe tracking measurement. For recording data

during the tracking measurement use key MEAS .

Measurements to inaccessible Points

The prism used for the distance measurementcannot be stationed on the desired point P.

Sight towards the point P and trigger themeasurement. Then, sight the prism stationed onthe auxiliary point H.Pay attention to the condition of equidistanceS-P = S-H.

If data recording is activated, only a data lineindicating the angle to P and the distance to H issaved.Naturally, the angle and distance to H aredisplayed after the measurement, being the anglevalue continuously updated in the EltaR display.

4 Coordinates

The basic requirement for a measurement in a

system of coordinates is a stationing within thissystem. That means, that the position and heightof the instrument are determined by measuring toknown backsight points.In the case of an unknown station, the scale andthe orientation of the Hz circle in azimuth directionare computed additionally to the stationcoordinates. In the case of a known station, onlythe scale and the orientation of the Hz circle inazimuth direction are computed.

After the stationing, the actual measurements -that means setting out and polar points - are

possible within this system of coordinates.

Station Point Memory EltaR

In a non-volatile instrument memory, the followingdata are retained after switching the instrument offand overwritten with every new determination:

Station coordinates Y,X,ZInstrument height ich

Reflector height thScale mOrientation Om

The coordinates of the station point are calculatedor entered by means of the coordinationprograms.During the following operations (setting-out / polarpoints), the user can access this memory at therespective parts of the program and does not haveto enter the values again.After having changed the station, these valueshave to be calculated or again entered in thecourse of the program.

Special Features of EltaR 50

The EltaR 50 (the instrument is not fitted outwith a data memory) has a memory location foranother single point (coor-memory) containing thecoordinates of this point (Y;X;Z) in a non-volatileform.This memory location permits a simpletransmission of coordinates (stationing with

"unknown station") with the EltaR 50 and sparesthe user the trouble to take the coordinates downor to enter them twice.


54/192

Window of the EltaR 50 when callingcoordinates

Method:

The station coordinates S1 are known or have beencalculated by means of a coordinate program. Thecoordinates of point K1 will be calculated with theprogram polar points and saved in the coor-

memory with .

After placing the instrument on S2, thecoordinates of the points S1 (last station) and K1(coor-memory) are called with the stationingprogram "unknown station" and used fordetermining the coordinates of S2.

Now, the coordinates of the point K2 can becalculated with the program "polar points" andstored in the "coor-memory". After changing theposition of the instrument to S3, the coordinatesof this point will be calculated in analogy to stationS2.

Data Management 3 Data Formats

Introduction

Zeiss Geodetic Systems are used for measurementfunctions with different data processing require-ments.

Elta instruments allow densely packed internalmeasurement and result data lines to be output invarious formats.

Four data formats which have grown historicallyare subject to on-site revision service for compati-bility with customer instruments. Currently, M5 isthe format

to provide most comprehensiveness in definitions.It should be used preferentially for any other tasks.

This chapter describes the structure of data formatand the type identifier of measured and calculatedvalues.

&User interfaceData management

CTechnical

All instruments have a serial interface whichensures the data exchange.

GAttention!

Instead of the usual marks within the 27 digitpoint identification, the M5 data format ofElta * R is limited to a 12 digit point numberand a 5 digit code.

Description of M5 data format

The Zeiss M5 data format is the common standardfor all current Carl Zeiss surveying systems.

All 5 data blocks are preceded by a type identifier.The 3 numerical data blocks have a standard layoutcomprising 14 digits. In addition to the decimalpoint and sign, they accept numeric values withthe specified number of decimal places.The information block is defined by 27 characters.It is used for point identification (PI) and text in-formation (TI e.g.).The address block is comprised of 5 digits (fromaddress 1 to 99999).

The M5 data line

The data line of the M5 format consists of 121

characters (bytes). The multiplication of this figureby the number of addresses (lines) stored showsthe size of the project file in bytes.

Blanks are significant characters in the M5 file andmust not be deleted.

The example describes an M5 data line at address176 with coordinates (YXZ) recorded in unit m.The point identification of marking 1 is DDKSS402 4201. Column 119 includes a blank (noerror code).

The end of the line has CR, LF (columns 120 and

121, shown here as 5 Measuring datablocksper data line:

Description of Rec 500 data format

With the electronic field bookRec500 a data for-mat was developed which was created for CZ in-struments years ago and is today the base for theM5 format..

The Rec500 format is divided in 5 marking blocks(analogous the M5 format). These blocks differ intheir block length from the M5 format, 80 charac-ters (Bytes) are available on a data line.

The Rec500 Data line

The data line in the Rec500 format is comprised of80 characters (Bytes).

Digits Characters Meaning (w. example)

4 numeric Memory address

27 num / alpha Point identification (14-digits) and additionalinformation (13 digits)

2 num / alpha D = slope distance12 numeric E = horizontal distance

Y = coordinate, etc.

2 num / alpha Hz=horizontal direction13 numeric X = coordinate, etc.

2 num / alpha V1=zenith angle9 numeric Z = coordinate, etc.

EltaR Markings in R4/ R5 format

In instruments of the EltaR Serie one markingcan be used.

In both the R4 and R5 format 7 characters areavailable for point identification and marking.

The PI is controlled by two type identifiers TR andKR, which mark the kind of the PI.

TR Type identifier for one text informationblock

KR Type identifier for a PI with code andpoint number.

Point number: 0...9, right-aligned,4-digit

Point code: 0...9, Blank, #3-digit

The 3 digits in the code can be combinedwith any applicable character. It is suggested, to use the character # to markincorrect measurements.

Examples:

TI 1234567

TR IIIIIII

KR CCCPPPP

Meaning:

7-digit Text information block

3-digit Code block

4-digit Point number block

In the M5 / Rec500 Format a 5-digit code and a12-digit point number are used. In the R4 / R5Format the established digits (3 and 4, respectively)remain right-aligned.

Definit ion of type identification

Type identifiers are assigned to the 5 measuringdata blocks of pre-set codes, which show thenumber or character value of the block.

Type identifiers are (except forAdr) defined withtwo characters. If only one character is necessary,the second character is blank. The code is casesensitive.

The following table lists all Type identifiers in al-phabetical order according to the CZ Data Formatsand the possible position of characters after thecomma (,????) as well as signs ():
