Welcome
to the JE DEPA V9 Introductory Tutorial! This document is engineered to
get you quickly up and running with DEPA V9 basics.
The core technology behind DEPA V9 is based on the American Society of Testing and Materials (ASTM) approved methodology called the Impulse Excitation Technique (IET). IET has found wide acceptance in industry and research due to its non-destructive nature, extreme accuracy, cost effectiveness and high result repeatability.
The simplicity of testing with the DEPA V9 software is one of its biggest selling points. The test sample is placed over a sonic sensor and excited with a small tap. The sound emanated by the sample is then broken down by the DEPA software into its component frequencies. The fundamental frequency intrinsic to the material is then analyzed to accurately reveal the material's characteristics.
