The Impact Testing software of the m+p Analyzer real time analyzer includes useful tools like the selection of a roving hammer or transducer, selection of data points/nodes, double impact detection and rejection, definition of force and exponential window and a user-definable display configuration as a visual measurement feedback.
The combination of automatic DOF/node scheduling, automatic rejection of invalid measurements and automatic saving of data after a user-defined interval virtually eliminates all keyboard interaction. This is helpful for impact testing on large structures or at locations that are difficult to access.
- Key Features
