Indoor & Outdoor Measurements
This model is designed to take measurements indoors and outdoors
under normal settings. The measuring surfaces and ambient light are
critical factors to the quality of measurement (indoors and 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.
