Clegg Control
Utilities
Free
The Lafayette Instrument Clegg Control app takes the place of a physical Clegg Control handheld device. Using this app, an operator can easily set up a test site and perform a test with limited manual input. An updated Quick Testing mode now allows testing multiple locations with the convenience of GPS location mapping while Advanced Testing Mode allows operators to enter preset sites and specific test locations in order to provide a consistent and more streamlined testing experience. Acquired data can be stored and viewed by test site, date, and test session. A simple data export process allows scoring data to be exported to other programs for further interpretation and comparison.
more Improved advanced test editing to ensure they update consistently.
No longer hiding the filter panel when filtering quick tests.
