Appendix A
Saving the New Calibration Coefficients: USB Mode
Ocean Optics programs wavelength calibration coefficients unique to each HR2000 onto an EEPROM memory
chip in the HR2000.
You can overwrite old calibration coefficients on the EEPROM if you are using the HR2000 via the USB port. If
you are using the HR2000 via the serial port, consult the Saving the New Calibration Coefficients: Serial Mode
section later in this Appendix.
To Save Wavelength Calibration Coefficients Using the USB Mode
1. Ensure that the HR2000 is connected to the PC and that you have closed all other applications.
2. Point your browser to
Microcode. Click on the USB EEPROM Programmer selection.
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.
7. Click
the
Next button. The Start Installation screen appears.
8. Click
the
Next button to begin the installation. Once the installation finishes, the Installation Complete
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 appropriate HR2000 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 section in this Appendix.
13. Repeat Step 12 for all of the new values.
14. Click on the Save All Values button to save the information, and then Exit the USB Programmer
software.
