Timer mikrodetik TreeSonic dirancang untuk prediksi kekakuan pohon. Ini mengukur waktu gelombang stres antara start dan stop transduser. Struktur alat TreeSonic dirancang oleh Weyerhaeuser Co. Peralatannya sedang menunggu paten, pemegang patennya adalah Weyerhaeuser Co.
usage instruction
- Connect the start and stop sensors to the START and STOP connectors of the timer. Make sure not to turn the plastic part of the connectors. The longer and flat shaped transducer is the start and the shorter, cube shaped one is the stop transducer.
- Drive the spike of the transducers into the tree you want to test using the sliding hammer.The spike need to penetrate through the bark and stabilize the transducer in the wood material. Please apply 45 degree as the angle between the spike and the fiber.
- The first time you hit the start transducer, the reading “9999” appears which means that the unit was switched on successfully. From that point on, all upcoming hits will show the actual transit times in microseconds.
- The unit switches of automatically after 30 seconds of inactivity.
