# THE EC II D-R

#### Height with Digital Distance Calculation,Form Factor, Basal Area & Volume

• Height, number of stems, basal area calculation and volume estimate
• Distance calculation at ref. height
• Basal area featured in the display
• Eliminates calculation errors
• Beaded chain extending to 60cm/24”
• Volume presentation based on input upper height x form factor x basal area

The EC II D-R is an electronic clinometer with a factor gauge and in-built functions to get estimates for basal area and volume. Use the EC II D-R for height readings from any manually measured and input distance or with a calculated distance.

The distance calculation is performed with trigonometry and a reference height set at 2m/6ft on the object to measure. The EC II D-R model also offers adjustable form factor from 0.10…0.95 (default 0.45). Use the built-in basal area functions to count number of stems in your EC II D-R with one of four basal area factors (0.5,1,2,4 or 5,10,20,40). The EC II D-R will automatically display a calculation of the basal area and give a volume estimate based on the dominant tree height or average height.

## HEIGHT

#### Calculate the distance with EC II D-R

For best possible results, stand as far from the tree as the tree is high when performing the measurement.To calculate the distance, set a reference height mark at 2m / 6ft on the tree.

• Put a mark on the tree at reference height 2m / 6ft. Walk away from the tree long enough to see the root, the reference mark and the top of the tree.
• First aim at the root and press the button until a signal is heard and the value freezes in the display.
• Aim at the reference height mark and press the button until the signal is heard and the value freezes. The calculated distance will show briefly.
• Aim at the tree top (or other height on the tree) and press the button until the signal is heard again and the value freezes. The calculated height value now shows in the instrument display.

# How to use EC II D-R and EC II D

#### Measure the distance manually

For best possible results, stand as far from the tree as the tree is high when performing the measurement.

• Measure the distance from the tree root to your eye. Use a measuring tape or thread meter. Move away from the tree until you can visualize the entire tree – both the root and the top of the tree.
• Enter the measured distance value in the EC II-D instrument.
• Aim at the root and press the button until a signal is heard and the value freezes in the display.
• Aim at the tree top (or other height on the tree) and press the button until the signal is heard and the value freezes.The calculated height now shows in the instrument display.
