4 OPERATING INSTRUCTIONS SOFTWARE
4.1 Requirements
•
PC with Windows 7 (or higher) operating system
•
one free USB port
4.2 Software installation
Install the iQ-LED control software before connecting the hardware. Follow the setup instruction
from the iQ-LED control software manual.
4.3 Starting the system
Start the iQ-
LED software by clicking the ‘iQ-LED.exe’ or the iQ-LED icon on your desktop.
Follow the iQ-LED software manual to control the CAL3.
NOTE
The iQ-LED devices can only operate with high precision, when setup and calibration
are performed correctly.
Consult the iQ-LED software manual for a comprehensive description and read it
carefully.
4.3.1 Spectrometer settings
The iQ-LED software (see iQ-LED software manual) automatically generates the best
spectrometer settings for you lighting conditions after pressing the
“auto detect” button. For
special applications, it is also possible to set the spectrometer settings manually. If you have
further question, please contact the Image Engineering support.
4.3.2 iQ-LED calibration
The individual LED lights of the iQ-LED inside the CAL3 depends on many different types and
wavelengths. Some LEDs will change their intensity level and peak wavelength slightly in the
first 500-600 working hours because of a burn-in effect.
The LEDs will also degrade in intensity during their lifetime. To make sure that all
measurements including the auto-generated illuminants and the standard illuminants, are
correct, you have to perform a spectral calibration regularly.
You must also consider the degradation of the LED when saving self-defined presets. If you
save a preset with LED channels that uses its maximum intensity, the possibility exists that this
intensity cannot be reached after the burn-in time or the long-time degradation of the LED. In
this case, you will get a warning message from the iQ-LED control software.
