Section 1 - Introducing the Criterion RD 1000
Congratulations on the purchase of your Criterion RD 1000, the first electronic
BAF-scope/dendrometer. Laser Technology, Inc. (LTI) designed the RD 1000
specifically to address the real world needs of forestry professionals. The RD 1000
is primarily an optical device that provides real-time results for calculations that
have to do with the BAF principle, tree height and diameter.
Features
• In-scope LED offers adjustable brightness levels and projects a
measurement bar scale that represents a subtended horizontal angle.
The RD 1000 uses this angular measurement and the horizontal distance
to the target tree to calculate the diameter of the tree stem. The
horizontal distance is the level distance between the eyepiece and the
point of measurement on the face of the tree. To enter the horizontal
distance to the target tree, you may:
¶ automatically download measurement data from an LTI laser
range finder.
¶ measure the distance to the tree using a tape measure and
then manually enter the value.
• Tilt sensor measures vertical angles, which the RD 1000 uses to
determine the slope-reduced measured distance and to calculate height.
The tilt sensor is capable of taking +/- 90º measurements (360º full
circle).
• Attachable Magnifier can be used when measuring diameters in
situations that require maximum measurement resolution.
• Ergonomically designed for handheld use, rugged, water and dust
resistant, and is small enough to carry in your vest pocket.
• Can be mounted on a tripod or monopod for increased precision.
• Works seamlessly with an LTI laser range finder and an external data
collector.
Measurement Types
The RD 1000 offers five different measurements. Of these five, three produce
results that may be downloaded to an external data collector.
• BAF: Visually estimate if trees fall “In” or “Out” of a given plot as related
to the specified Basal Area Factor.
• In / Out: Use the internally stored plot radius factors to determine the
status of a “borderline” tree.
• Diameter: Determine the diameter of a tree at any given height. Result
may be downloaded to an external data collector.
• Height / Diameter: Verify the height at which a specified diameter is
reached. Result may be downloaded to an external data collector.
• Raw Inclination: Displayed as Percent Slope. Result may be
downloaded to an external data collector.
