Introduction TreeSonic microsecond timer is designed for tree stiffness prediction, measures the stress wave time between start and stop transducer. The structure of TreeSonic tool is designed by Weyerhaeuser Co. The equipment is patent pending. Patent holder is Weyerhaeuser Co. Preparation for the work Connect the start sensor to the start connector of the timer. Please see the male and female connector first and use proper orientation while pushing the connector. Finally lock the connector by turning the metal part of the connector clockwise. At this step never touch the black plastic...

Drive in the spike of the transducers into the tree you want to test using the sliding hammer. Spike need to penetrate through the bark and stabilize the transducer in the wood material. Please apply 45 degree as spike and fiber angle. See figure 2. Please do not bend the tip while inserting (straight in and avoid the knots) and extracting (straight and completely out) the probes. Figure 2. Driving the start (left) and stop (right) transducers into the tree using sliding hammer Instead of on/off switch There is no on/off switch on the unit. For switching on please hit the start transducer,...

switches of automatically if no hit on start sensor arrives within 30 seconds. This function saves the battery. The standard setup is shown on figure 3. The recommended distance between transducer is 1 meter. There is a 1 m mark on the start transducer cable. Figure 3. The recommended setup. Record the readout. Using the average of 3 readouts is recommended. The standard deviation of the readout is less than +/1.5 microseconds. 4

Safety The transducer has sharp spike. Pleas take care of the spike of the sensor, may injure yourself or person nearby you. When out of use please apply protector tube. Wearing safety shoes, safety glass and gloves is recommended. Fix upper (starter) probe properly, if probe would fall down, never catch while falling. In this case step back, and let it fall down. Maintenance After 10-12 hours operation time, batter goes down. A “BAT LOW” message appears on the screen. Your battery is rechargeable, capacity is 100 mAh. Figure 4. shows how to open the battery compartment. Figure 4. The door...
