Preparation
Before determining the instrument errors, the instrument has to
be levelled using the electronic level.
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 conditions are early in the morning or with
overcast sky.
Before starting to work, the instrument has to become acclimatised to the
ambient temperature. Approximately two minutes per °C of temperature differ-
ence from storage to working environment, but at least 15 min, should be
taken into account.
