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
Ocean Optics programs wavelength calibration coefficients unique to each Apex onto an EEPROM
memory chip in the Apex.
You can overwrite old calibration coefficients on the EEPROM if you are using SpectraSuite software.
►
Procedure
To save wavelength calibration coefficients using the USB mode, perform the following steps:
1. Ensure that the Apex is connected to the PC.
2. Open SpectraSuite software.
3. Select Spectrometer | Spectrometer Features from the menu, or right-click on the Apex in the
Data Sources pane and select Spectrometer Features.
4. Select the Wavelength tab.
5. Enter the new values acquired in Steps 5 and 6 of the
Calibrating the Wavelength of the
6. Click Save to Spectrometer.
The new wavelength calibration coefficients are now loaded onto the EEPROM memory chip on the
Apex.
