Optical alignment
Once the Remote Head is fastened, adjust the two alignment screws on the X-Y mount so
that the Retro appears in the centre of the cross hairs in the alignment scope.
Verify that the entire Retro is clearly visible and there are no obstructions in the path.
Ensure that the GasFinderMC is enabled and locked to the
channel being adjusted. Connect the Remote Light Meter
(RLM) to the coaxial fi tting on the rear of the head. Adjust the
X-Y mount with the horizontal and vertical adjustment screws
so that the reading on the RLM is as high as possible. Gently
tighten the 4 red locking screws on the mount, ensuring that
the reading on the RLM does not decrease. Note that the RLM
will read about 1/10 the value shown at the
GasFinderMC.
A reading below 200 is an indication that more refl ectors are
required on that path.
A reading greater than 2000 is an indication that the laser
signal may have to be attenuated.
If the retrorefl ector is not visible in the alignment scope or
diffi culty is experienced getting a reading on the RLM, connect
the visible laser to the fi bre connector located above the coaxial
connector. Switch on the visible laser. Using the continuous
red beam now being emitted from the Remote Head, the mount
can be adjusted so that the red beam is refl ected back from
the retrorefl ector. As soon as the RLM registers a reading, the
visible laser use can be discontinued and the RLM used for
precise alignment.
Note: the refl ected beam of the visible laser is very bright
and should not be observed through the aiming scope.
The iaiming laser output from the Visible Laser has very low power (conforms to Class
1 as per IEC 60825-1) and will not damage eye tissue.
