The built-in user interface is Megger’s second generation of automatic / semi-automatic manual user interface running the FREJA Local software. The large, easy to read Full Color high resolution, high definition, TFT LCD touch-screen display allows the user to perform manual, steady-state and dynamic testing quickly and easily.

FREJA Local includes built-in preset test routines for automatic testing. Menu screens and touch screen function buttons are provided to quickly and easily select the desired test function. Tests and results can be saved in FREJA Local memory and downloaded to a USB memory stick for transfer or print test reports. For full automatic testing the FREJA Win software will be used with a PC.
