Line-of-sight error
Before starting to work, the instrument has to become acclimatised to the ambient
temperature. Approximately two minutes per °C of temperature difference from
storage to working environment, but at least 15 min, should be taken into account.

Adjusting Line-of-Sight and Vertical Index Error

The line-of-sight error, or horizontal collimation error is the deviation from the
perpendicular between the tilting axis and the line of sight. The effect of the line-of-
sight error to the horizontal direction increases with the vertical angle.
