Illumination Angle
Enter the illumination beam angle in [°deg]
7.4 Synchronized Measurement
This option is not available with this version of FluxGage
7.5 Indicators
7.5.1 Integration time
This is the integration time of the spectrometer. It should be adjusted such that ‘over exposure’
and ‘under exposure’ indicators are off.
The photovoltaics and photodiode collect light for 500ms minimum.
7.5.2 Out of range
The out of range warning will turn on in these cases:

Amount of light is too high or too low for the current settings and ‘Autoset’ and
‘Background’ should be repeated.

Flux level exceed 40,000 lumen
7.5.3 Temperature
The FluxGage has an internal temperature sensor and 4 fans which turn on automatically to
keep a stable temperature. If for some reason, such as failure of the fans, the FluxGage is
overheating, the temperature warning indicator will turn on. In this case, the FluxGage should
be turned off and the DUT should be removed to allow the FluxGage to cool down.
7.6 Measured Parameters
7.6.1 Total Flux [lumens]
Total luminous flux in lumens
7.6.2 CCT
Correlated color temperature (CCT) in [°K] is calculated from the measured spectrum.
7.6.3 CRI
CRI is calculated from the measured spectrum.
