Attention

mains cable and plugs of accessories have to be The in perfect condition. When working with the tachymeter rod near to electrical installations (for example electric railways, aerial lines, transmitting stations and others), there is acute danger to life, independent of the rod material. Inform in these cases the relevant and authorised security offices and follow their instructions. Keep sufficient distance to the electrical installations. Avoid surveying during thunderstorms because of lightning danger.

First Steps

The first steps cover up the set-up of the instrument, including the explanation of basic inputs and the necessary presettings. After having set the parameters for saving and entered the point information, you can measure in the start-up menu. 1 Before Measurement 3-2

1 Before Measurement
Set-Up and Coarse Centring
In order to guarantee the stability of measurement we recommend the use of a Zeiss S27 Tripod.
Set-up: Extend the tripod legs (1) to a comfortable height of observation and fix them using the tripod locking screws (2). Screw the instrument centrally to 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 be approximately 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 the eyepiece of the optical plummet.
Levelling and Fine Centring Coarse Levelling: Level the circular bubble (6) by adjusting the length of the tripod legs (1).

Precision Levelling:

Align the control unit parallel with the imaginary connecting line between two tribrach screws. Level the instrument by turning the tribrach screws a) and b) in opposite directions. Turn the instrument by 100 gon in Hz and level instrument with tribrach screw c).For checking, turn the instrument round the vertical axis. After that, check the residual inclination by turning the instrument in both diametral positions of (1) and (2). Take the mean of deviation from center point of level and adjust, if necessary. Precision Centring: Shift the tribrach on the tripod head plate until the image of the ground mark is in the centre of the circular mark of the optical plummet; repeat the levelling various times if necessary.

Station

Sight towards the point P and trigger the measurement. Then, sight the prism stationed on the auxiliary point H. Pay attention to the condition of equidistance S-P = S-H. If data recording is activated, only a data line indicating the angle to P and the distance to H is saved. Naturally, the angle and distance to H are displayed after the measurement, being the angle value continuously updated in the Elta R display.
The required presettings are to be subdivided into three groups: Settings in the Start-up Menu Specify measuring units for angle and distance Short-time setting of V angle in percent Activating and deactivating the compensator Orientation of Hz circle Frequently used Settings Input of pressure and temperature Input of scale and addition constant Rarely used Set Instructions Display mode for angle and distance Vertical reference system System of coordinates Display of coordinates Measuring units of temperature, pressure Switching the instrument automatically off Switching the acoustic signal on and off Regulation of display contrast and brightness of crossline illumination

F Tip Prior to each measurement with MEAS it is possible to enter a point number and a code for the point to be measured. In the stationing programs, the codes (A, B, S) have been invariably set. Point numbers can be entered. The point number is incremented automatically by 1. The code that has been set is saved with every measurement until being modified by the user.

to trigger measurement

In the setting-out program, the possibility to measure is indicated additionally by the symbol in the display
Station Point Memory Elta R In a non-volatile instrument memory, the following data are retained after switching the instrument off and overwritten with every new determination: Station coordinates Instrument height Reflector height Scale Orientation Y,X,Z ich th m Om
The coordinates of the station point are calculated or entered by means of the coordination programs. During the following operations (setting-out / polar points), the user can access this memory at the respective parts of the program and does not have to enter the values again. After having changed the station, these values have to be calculated or again entered in the course of the program. Special Features of Elta R 50 The Elta R 50 (the instrument is not fitted out with a data memory) has a memory location for another single point (coor-memory) containing the coordinates of this point (Y;X;Z) in a non-volatile form. This memory location permits a simple transmission of coordinates (stationing with "unknown station") with the Elta R 50 and spares the user the trouble to take the coordinates down or to enter them twice.
Elta R Principle of transmission of coordinates unknown station"

After having entered the coordinates of the point to be set out and measured the approximate point, the Elta R displays the result in the form of the longitudinal deviation dl, the transverse deviation dq, the angle Hz between the approximate point and the nominal point, the radial deviation dr and the deviations of the coordinates dx, dy and dz.

Reduction Formulae Slope distance SD
Distance between the instruments trunnion axis and the prism. It is computed from the measured slope distance and the entered scale: SD= Dk M SD= displayed slope distance Dk= basic distance M = scale

Horizontal distance HD

HD= ( E1 + E2 ) M HD= displayed horizontal distance E1= Dk sin ( Z + R ) R = influence of refraction = 6.5 10-7 Dk sin ( Z ) E2= influence of earth curvature

Distance reduction to MSL
Distances measured at elevation Z can be red uced to MSL by computing the following scale outside the instrument (computation formula applies to all earth radii): m = R / R+Z S2 = S1 R Z S1 S2
= earth radius ( 6370 Km ) = elevation above MSL ( Km ) = measured distance at elevation Z = reduced distance at MS L
If this scale is entered into the Elta R, the computed distances are reduced directly in the instrument.
Verifying on Calibration Distances Basically, all measured distances are corrected with reference to: the entered scale, the entered addition constant, the influence of pressure and temperature, internal influencing variables.
G Attention! Prior to the practical realisation of the calibration measurement, the current values of the parameters scale, addition constant, pressure and temperature are to be e ntered. The scale is to be set to default: 1.000000. This is to secure that all corre ctions are made completely and perfectly. Furthermore, this allows a direct compar ison of nominal and actual values in the case of given distances.
If a weather correction is to be carried out externally, the temperature must be set to 20C and the air pressure to 944 hPa. Then, the internal correction goes to zero.

Prism and Addition Constants All total stations manufactured by Carl Zeiss, in combination with their reflectors are adjusted with the addition constant 0.000. In case of measurements to reflectors of other manufacturers, a possibly existing addition constant can be determined by measurement and entered. Another possibility consists in calculating an addition constant by means of the known prism constant of the reflector used and entering it. This prism constant is calculated as function of the geometric value of the prism, the type of glass and the place of the mechanical reference point. The prism constant for Carl Zeiss reflectors determined that way is -35 mm. Relation between the addition constant Acz for Zeiss instruments, the prism constant Pcz for Zeiss reflectors and the prism constant P f for other manufacturers: Acz = P - P F CZ Example: Zeiss reflector Pcz Foreign reflector P
prism constant = -35 mm prism constant = -30 mm
Addition constant for Zeiss instruments in connection with this foreign reflector Acz = + 5 mm
In this case, in the Elta R the addition constant + 0.005 m is set.

Eccentric Inlet Flow

Eccentric air distribution at fan inlet diminishes fan performance by up to 45% because the main flow is accelerated through an effectively smaller duct area on one side while turbulence and high intensity pressure fluctuations occur on the other. Noise level is also increased.
Rated fan performance is only achieved when air flows evenly into the fan impeller.

Hideaway SH - In-Line

The Hideaway SH is a range of duct mounted in-line centrifugal fans designed specifically for installations where space is at a premium and noise levels are an important design criteria.
6 standard sizes from 100mm to 315mm. Air volume flow rates of up to 0.33 m3/sec. Static pressures of up to 500 Pa. Motors are external rotor, protected to IP44 with Class B Insulation.
