ASC uses high-tech equipment to maximize accuracy and ensure consistent results for all tests. Velocity testing is performed with the 3DDAS™, a computerized data acquisition system that guides the user through the Method 2 test procedures to ensure success. The 3DDAS™ takes 1000 readings per second and calculates averages instantly. There are no fluctuating gauges that can result in human averaging; all data is collected electronically.
