4.2 Preparation



Before starting to work, the instrument has to become acclimatised to the ambient temperature. Approx-
imately two minutes per °C of temperature difference from storage to working environment, but at least
15 min, should be taken into account.

Even after adjustment of the Aim360, the crosshairs may not be positioned exactly on the centre of the
prism after an Aim360 measurement has been completed. This outcome is a normal effect. The telescope
is not normally positioned exactly on the centre of the prism, to speed up the Aim360 measurement. These
small deviations/Aim360 offsets, are calculated individually for each measurement and corrected electron-
ically. This means that the horizontal and vertical angles are corrected twice: first by the determined
Aim360 errors for Hz and V, and then by the individual small deviations of the current aiming.

4.3 Combined Adjustment (l, t, i, c and Aim360)
Description The combined adjustment procedure determines the following instrument errors in one process:
Before determining the instrument errors, the instrument has to be levelled using the elec-
tronic level. SHIFT (F12) to access STATUS Level & Laser Plummet, Level page.
The tribrach, the tripod and the underground should be stable and secure from vibrations or
other disturbances.
The instrument should be protected from direct sunlight to avoid thermal warming.
It is also recommended to avoid strong heat shimmer and air turbulence. The best condi-
tions are early in the morning or with overcast sky.
IF the task is to THEN
adjust a combination of instrument
errors Refer to "4.3 Combined Adjustment (l, t, i, c and Aim360)".
adjust the tilting axis Refer to "4.4 Tilting Axis Adjustment (a)".
adjust the circular level Refer to "4.5 Adjusting the Circular Level of the Instrument and
Tribrach".
adjust the laser/optical plummet Refer to "4.7 Inspecting the Laser Plummet of the Instrument".
adjust the tripod Refer to "4.8 Servicing the Tripod".
l, t Compensator longitudinal and transversal index errors
i Vertical index error, related to the standing axis
c Horizontal collimation error, also called line of sight error
Aim360 Hz Aim360 zero point error for horizontal angle option
Aim360 V Aim360 zero point error for vertical angle option
