The Laser Pointer
The Spectra Precision FOCUS 35 Total Station uses a red laser beam to measure and as a Laser
Pointer. The Laser Pointer is coaxial with the line of sight of the telescope. If the instrument is well
adjusted, the red Laser Pointer coincides with the line of sight. External influences such as shock or
large temperature fluctuations can displace the red Laser Pointer relative to the line of sight.

To avoid faulty measurements using the Laser Pointer, use the supplied adjustment target to check
the laser alignment regularly and before you attempt precise distance measurements:
1. Setup the adjustment target 10-15 meters (30-50 ft) away, facing the instrument.
2. Aim the instrument to the center of the target plate and then inspect the position of the red laser
spot in relation to the telescope cross-hairs.
3. If the red laser spot lies outside the cross-hairs, adjust the direction of the beam until it matches
the cross-hairs, see the Laser adjustment plate, below:
