7. Record the Intercept, as well as the First, Second, and Third Coefficients. Additionally,
look at the value for R squared. It should be very close to 1. If not, you have most likely
assigned one of your wavelengths incorrectly.
Keep these values at hand.
Saving the New Calibration Coefficients: USB Mode
Ocean Optics programs wavelength calibration coefficients unique to each Flame onto an
EEPROM memory chip in the Flame.
You can overwrite old calibration coefficients on the EEPROM
if you are using the Flame via the
USB port.
►
Procedure
To save wavelength calibration coefficients using the USB mode, perform the following
steps:
1. Ensure that the Flame is connected to the computer and that you have closed all other
applications.
2. Point your browser to

and scroll down to
Microcode
. Select
USB EEPROM Programmer
.
3. Save the setup file to your computer.
4. Run the
Setup.exe
file to install the software. The
Welcome
screen appears.
5. Click the
Next
button. The
Destination Location
screen appears.
6. Accept the default installation location, or click the
Browse
button to specify a
directory. Then, click the
Next
button. The
Program Manager Group

screen appears.
9. Click the
Finish
button and reboot the computer when prompted.
10. Navigate to the
USB EEPROM Programmer
from the Start menu and run the
software.
11. Click on the desired Flame device displayed in the left pane of the
USB Programmer
screen.
12. Double-click on each of the calibration coefficients displayed in the right pane of the USB
Programmer screen and enter the new values acquired in Steps 5 and 6 of the
Calibrating the Wavelength of the Spectrometer
13. Repeat Step 12 for all of the new values.
