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.
