The software is split in an unskilled operator mode, an engineer setup mode and an R&D engineer mode. As a return of a test in operator mode an approved / reject or as a full graph will be displayed. At same time measured data for further statistical analyze can be stored.
Tool
s to find the golden unit from stored data.

The systems make use of a unique password control and a unique recovery manager.
