Indoor & Outdoor Measurements
This model is designed to take measurements indoors under normal
settings. The measuring surfaces and ambient light are critical factors
to the quality of measurement (indoors an outdoors). Outdoor
measurement capability may be limited due to sunlight/UV ray
interference. Please note that in some situations the unit may have
difficulty reading the surface you try to measure if lighting or sunlight
is intense and/or the surface being measured does not reflect the
laser beam appropriately.
