Builder, Check & Adjust
The following instrument parts can be adjusted mechanically:
• Circular level on instrument and tribrach
• Laser plummet
• Screws on tripod
• Visible red laser beam for Builder 200 or higher. Only Leica Geosystems author-
ized service workshops are entitled to adjust these products.
• Vertical line of the reticule for Builder 100.
During the manufacturing process, the instrument errors are carefully determined
and set to zero. As mentioned above, these errors can change and it is highly recom-
mended to redetermine them in the following situations:
• Before the first use
• Before every high precision survey
• After rough or long transportations
• After long working periods
• After long storage periods
• If the temperature difference between current environment and the temperature
at the last calibration is more than 20°C
