4Setting Up The FGC100
Place the FluxGage box on a flat surface.
Place the lid over the FluxGage. Make sure the lid is placed such that the round cover is
over the spectrometer diffuser.
Remove the round cover from the lid
Remove the protective cover from the FGC100 lamp unit
Insert the FGC100 lamp unit into the hole in the lid and secure it using the two thumb
screws
Connect the D-type cable between the FGC100 control unit and the FGC100 lamp unit
Connect the output cable of the 12VDC adapter to the FGC100 control unit
Connect the mains cable to the 12VDC adapter and plug it into a mains socket

4.1 Operating the FGC100
Figure 6. FGC100 Control Unit - Front
Turn the control unit on using the on/off switch (on the left)
Press the LED on/off push button to turn on the lamp unit
The temperature indicator will be red initially and will turn to green after a few minutes when
the temperature of the lamp unit will be stabilized. However, wait at least 30 minutes before
using the FGC100.
The hour meter display the total time in which the LED in the lamp unit was on. After 75 hours,
the FGC100 (lamp unit and control unit) should be sent to Ophir for recalibration.

FGC100 User Manual 11
5.1 Calibration of the spectrum measurement and the total flux
measurement
Follow these steps:
To calibrate the FluxGage click ‘Calibration’ on the top banner of the FluxGage software.
In the setting area, enter the total luminous flux of the FGC100. The value is provided
with the Disk-On-Key included in the FGC100.
Click ‘Open Light File’ and select the spectral calibration file provided with the Disk-On-
Key included in the FGC100.
If the file is loaded correctly, the ‘calibration file valid’ indicator will turn green.
Turn on the FGC100 lamp unit.
Press ‘Autoset’ and wait for the operation to complete.
In the setting area, select 30 averages.
Turn the FGC100 lamp unit off.
Press ‘Background’and wait for the operation to complete.
Turn the FGC100 lamp unit on, and allow enough time to reach thermal stabilization
(~30minutes).
Press ‘Calibrate’ and wait for the operation to complete.
At the top of the screen, the measured flux of the calibration source will appear. It
should match the value entered in the settings area.
Click on the top right corner to exit the window.
5.2 Calibration of the total flux measurement only
Follow these steps:
To calibrate the FluxGage click ‘Calibration’ on the top banner of the FluxGage software.
In the setting area, enter the total luminous flux of the FGC100. The value is provided
with the Disk-On-Key included in the FGC100.
Press the push button to turn the FGC100 lamp unit on.
Press ‘Autoset’ and wait for the operation to complete.
In the setting area, select 30 averages.
Press the push button again to turn the FGC100 lamp unit off.
Press ‘Background’ and wait for the operation to complete.
Press the push button to turn the FGC100 lamp unit on, and allow enough time to reach
thermal stabilization (~30minutes).
Press ‘Calibrate’ and wait for the operation to complete.
At the top of the screen, the measured flux of the calibration source will appear. It
should match the value entered in the settings area.
Click on the top right corner to exit the window.

5.3 Calibration of the spectrometer only
Follow these steps:
To calibrate the FluxGage click ‘Calibration’ on the top banner of the FluxGage software.
In the setting area, enter the total luminous flux value zero
Click ‘Open Light File’ and select the spectral calibration file provided with the Disk-On-
Key included in the FGC100.
If the file is loaded correctly, the ‘calibration file valid’ indicator will turn green.
Press the push button to turn the FGC100 lamp unit on.
Press ‘Autoset’ and wait for the operation to complete.
In the setting area, select 30 averages.
Press the push button again to turn the FGC100 lamp unit off.
Press ‘Background’ and wait for the operation to complete.
Press the push button to turn the FGC100 lamp unit on, and allow enough time to reach
thermal stabilization (~30minutes).
Press ‘Calibrate’ and wait for the operation to complete.
At the top of the screen, the measured flux of the calibration source will appear. It
should match the value entered in the settings area.
Click on the top right corner to exit the window.
5.4 Back up calibration
In addition to the working calibration there is a backup calibration.
The backup calibration can be retrieved by pressing ‘restore back up calibration’. This will copy
the backup calibration into the working calibration. The backup calibration can be overwritten
by pressing ‘over write back up calibration’. This should be done when the calibration is done
with an Ophir certified calibration unit.
