Operation 87
ment may be made to the side of the vehicle. The result is the distance to the vehicle,
not to the road surface.
If using the red laser EDM for long range measurements to a prism, and an object
passes within 30 m of the EDM as
DIST (F2) or ALL (F1) is pressed, the distance
measurement may be similarly effected due to the strength of the laser signal.

Due to laser safety regulations and measuring accuracy, using the Long Range
Reflectorless EDM is only allowed to prisms that are more than 1000 m (3300 ft)
away.
Accurate measurements to prisms should be made in IR mode.
When a distance measurement is triggered, the EDM measures to the object which
is in the beam path at that moment. If a temporary obstruction, for example a passing
vehicle, heavy rain, fog or snow is between the instrument and the point to be meas-
ured, the EDM may measure to the obstruction.
Do not measure with two instruments to the same target simultaneously to avoid
getting mixed return signals.
ATR/lock Instruments equipped with an ATR sensor permit automatic angle and distance
measurements to prisms. The prism is sighted with the optical sight. After initiating
a distance measurement, the instrument sights the prism centre automatically.
