GasFinder2 Alignment
General
I
f the retro is not visible in the alignment scope or diffi culty
is experienced getting a reading of light level, the red visible
laser can be used to align the main laser.
With the • GasFinder2 in the Main Menu mode, scroll
down to the Light Value / Distance item.
Using the continuous red beam now being emitted from •
GasFinder2 , the X-Y mount can be adjusted so that the
red beam is refl ected back from the retro.
As soon as the Light Value indicates a reading above 100, the visible laser use can •
be discontinued and the maximisation of the Light Value reading used for precise
alignment.
Note: The refl ected beam of the visible laser is very bright and should not be observed
through the scope.
The range of the light value is between 1000 and 16,368 but the preferred value is between
4000 and 8000. Below 1000 the display will indicate “Low Light”. There is no indication that the
returning light has exceeded 16,368 so care should be taken to ensure that the returning light
does not exceed 14,000. The light value can be adjusted with the use of different retros.
Note: If the guidelines on page 3.3 have not been followed, it is possible to get too much
light returned (>16,368). When this happens the receiver saturates and the displayed
light value will read very low (<200). In this situation the gas concentration readings
will be in error and it is also possible to cause damage to the optical components.
