Boreal Laser Inc. GasFinderFCr Operation Manual –– Operating Instructions

If the light value is below 1,000, the system is in a minimal light situation and may fail to make
a correct measurement. When the light value drops below a factory set value, usually 1000,
the system will give a status message in the display indicating “ low light - no reading”. To
increase the light value, re-align the instrument, adjust the attenuator or increase the number
of retros.
Caution
: Do not look at the refl ector through the scope over short distances when the
red laser is operating.
