edges or are too close to the ground.

Figure 2.3: Unrecommended Mounting

TereScope not at edge of roof.

Beam path passes too close to ground. Heat rising causes scintillation.
Allow 4.5 m (15 ft) between ground and beam path.

Less than 4.5 m (15 ft) between beam
path and heat-emitting surface.

Beam path more than
4.5 m (15 ft) above
surface to avoid traffic
and rising heat.

TereScope at edge of roof so
that heat rising from roof
surface does not affect beam
