This app functions as the user interface for all of the GCTS SCON-S based devices (ePVC, ePCP, eFRM, eRCT, etc) and the GCTS DataCube. It allows the user to perform tests using either a curated selection of test modes based on different material standards, or personalize every detail of their test using Universal test mode. Our state-of-the-art controller allows fine-tuning of several parameters that makes it very versatile for testing.
