8 Adjusting the Light Output
Your S2000 system includes an iris adjustment to control the intensity level of the
light output from the unit. The intensity level adjustment is only possible when the
front panel LEVEL LED mode indicator is illuminated.
The S2000 system offers 2 different operating modes:
Relative or Absolute
.
Relative Mode
: offers an un-calibrated intensity level output which is displayed as a
percentage of iris opening on the LED display.
Absolute Mode
: offers a calibrated intensity level output from the unit which is
displayed in irradiance (W/cm2) on the LED display. This mode is only accessible
only when the S2000 has been calibrated with an R2000 Radiometer (front panel
Calibration LED is ON).
8.1
Adjusting the Light Output in the Relative Mode (“CAL” LED is OFF)
8.1.1
Set your OmniCure S2000 to Level Mode by pressing the Mode button until the
“LEVEL” LED on the front panel is illuminated. The “CAL” LED indicator will be
OFF. The display will show CLF and the Closed-Loop Feedback LED will be
illuminated. The only exception is when the unit is set to 100%, for maximum
output power. In this case; the Closed-Loop Feedback option is not activated
(Closed-Loop Feedback LED will be OFF) and the LED display will indicate 100
(% of iris opening).
Note:
The Closed-Loop Feedback LED will be OFF if the exposure alarm is
activated or the iris is at 100%.
Note:
Closed Loop Feedback shut-off @exposure time of .3 sec and lower.
Warning:
UV light will be emitted from the light guide. The light could severely damage the
cornea and retina of the eye if the light is observed directly. UV protective eye
shielding must be used at all times as well as clothing to protect exposed skin.
Note:
Removing the light guide from the front panel optical port while in
Absolute Mode will cancel the unit‟s calibration, and the unit will
automatically return back to the Relative Mode (CAL LED will turn OFF).
Note:
The shutter will not open if the light guide is not inserted properly.
