Ultrasonic velocity is a basic parameter for the nondestructive evaluation of trees, seedlings, woods, veneers, wood panel products and concrete. Defect localization and material property determination is possible by measuring ultrasonic velocity. This equipment is designed for veneer and seedling tests.

1. Connect the two pieso-electric transducers' cables     to the "probes" connectors of the timer.

2. Couple the transducer to the sample. Poor coupling     results in poor or incorrect result.

3. Switch on the timer. Transit time in μs appears on     the screen. The first readout after switch on is “0000”. This is normal.

4. Please check 2-3 readouts. If the deviation between     the readouts is not more than 1 μs, accept the data. Record the readout     and change sample.
