Adjusting the Light Output
Your S2000 Elite system includes an iris adjustment to control the intensity level of the light
output from the unit. When on the RUN screen, the touch panel or navigation keypad can be
used to quickly adjust the intensity level of the light output.
UP/DOWN - Exposure Intensity Adjustment
LEFT/RIGHT - Exposure Duration Adjustment
The S2000 Elite system offers two different operating modes for intensity control: Relative or
Absolute.
Relative Mode (Default): This mode offers an un-calibrated intensity level, in which the
outputted light intensity is proportional to the percentage of the iris opening. The value is
shown on the RUN screen as a percentage.
Absolute Mode: This mode offers a calibrated intensity level output and is only accessible
when the S2000 Elite has been calibrated with an R2000 radiometer. The value is shown on
the RUN screen in irradiance (W/cm
2
) or in units of power (W).
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 to the Relative
Mode.
