When “Not enough reflection” is displayed
•
Shorten the distance to the detection point.
•
Perform measurement from a perpendicular angle
rather than a slanting angle against a reflecting
object at the detection point.
CAUSE
Insufficient received light
When “Too much reflection” is displayed
•
Change the detection direction or the angle of the
product so that external light such as sunlight does
not get in the unit.
•
Change the detection point so that strong light
does not get in the unit.
CAUSE
Strong light such as sunlight is getting
inside the light receiver.
This may be caused by an object with
extremely high reflection such as a mirror.
When “High density gas” is displayed
•
The detectable range of this product is between 1
~
50,000
ppm·m.
•
The full scale is 50,000 ppm·m
.
CAUSE
When detecting methane thicker than
50,000 ppm·m, this product cannot
measure correctly.
