6 POWER AND CURRENT OPERATION MODES
6.1 POWER OPERATION MODE
1. Press the horizontal menu button under the Lamp Mode icon on the LCD display until the text under
Lamp Mode reads power as shown in the figure above. Upon reaching the Constant Power mode
option, the vertical menu for setting the lamp operating power (Pset) and maximum power to be supplied
to the lamp (Pmax) will appear as shown above.
2. To adjust the Pset and Pmax, press the vertical menu button next to each parameter. A red bullet in
the box indicating that particular parameter can be changed will appear. That parameter can now be
changed by rotating the knob to the right of the vertical menu buttons. Be aware that Pmax cannot be
changed when the lamp is ignited.
Note. If using a lamp purchased from Newport Corporation, set Pset to the desired operating
power. Pmax is typically set at 10% higher than the lamp rating. If not using a lamp purchased
from Newport Corporation, it is best to follow operation power and maximum power supply
guidelines determined by the lamp manufacturer.
