•Before every procedure, carefully inspect the equipment to ensure it has been properly maintained and
cleaned, and that it is fully functional. DO NOT use if inspection reveals anything unusual, including case
damage or loose connectors.
•SAFETY PRECAUTIONS MUST ALWAYS BE EXERCISED WHEN USING ELECTRICAL EQUIPMENT TO PREVENT
OPERATOR SHOCK, FIRE HAZARD OR EQUIPMENT DAMAGE.
•Don’t touch any exposed wiring.
•All electrical equipment must be used with approved power cords and power plugs inserted properly into
grounded AC power outlets.
•Don’t plug in the power cord until directed to by the installation instructions.
•Don’t bypass the power cord’s ground lead with two-wire extension cords or plug adaptors.
•Don’t disconnect the green and yellow safety-earth-ground wire that connects the ground lug of the power
receptacle to the chassis ground terminal (marked with or
!
).
•To reduce the risk of fire and electric shock, do not expose electrical equipment to moisture. When

SECTION 1 INTRODUCTION
1.1 General Information
Gamma Scientific’s SpectralLED® Tunable LED Light Source (Model: RS-7) is a multi-channel light source capable
of providing single channel illumination or broadband illumination using multiple channels. It is designed to
simulate broadband illuminants or any arbitrary spectrum by precisely combining the output of its LED channels
closely recreate real-world spectra. Gamma Scientific’s RS-7 features near perfect linearity and uniformity over
the entire intensity range, and comes with NIST-traceable absolute calibrations.
1.1.1 Features
•Multi-Channel LED Light Source covering a wavelength range from 360nm to 1000nm
•Digital Linear DC Drive Current Control
•High Dynamic Intensity Range (16 bit)
•Built-in Photodiode Feedback
•NIST Traceable Irradiance Calibration
•Long Lifetime
1.1.2 Precautions
WARNING:
Maintain ground to avoid electric shock
Disconnect power cord before replacing fuse
Replace fuse with same type and rating only
WARNING:
No user serviceable parts inside
Service by a qualified Gamma Scientific professional only
