10 Adjusting the Light Output
Your S2000 PRO/ELITE system includes an iris adjustment to control the intensity
level of the light output from the unit. The intensity level adjustment is possible from
the RUN screen using the touch panel or the navigation UP and navigation Down
button.
The S2000 PRO/ELITE 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 LCD display.
Absolute Mode: offers a calibrated intensity level output from the unit which is
displayed in irradiance (W/cm2) on the LCD display. This mode is accessible only
when the S2000 PRO/ELITE has been calibrated with an R2000 Radiometer
10.1 Adjusting the Light Output in the Relative Mode (“CAL” LED is OFF)
10.1.1 - Blank -
Note: The Closed-Loop Feedback 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.
Note: The shutter will not open if the light guide is not inserted properly.
