VERDI Laser parameters

During its standard operation in the test cave, the VERDI Laser delivers an output power of  4 W (I=25.35A). When the shutter is closed, the current drops to 20.18 A. Note that before turning the Laser ON, you have to make sure that the chiller operates at a temperature of 19 C.

To acces special parameters, hit the Menu key on the controller and scroll (up/down) to get to the desired screen, then hit Select. When done, press Exit to return to the standard parameters screen.
