Ocean Optics with Xplorer GLX Spectrometer Analysis Configuration Screen

E. Configure the Spectrometer

In the Spectrometer Analysis Configuration screen, follow these general

steps. (For a detailed explanation of the parameters in the configuration

screen and how to change them, see pages 3–6.)

1. Set the parameters in the Data Acquisition tab as desired.

2. (This step is not always necessary.) Go to the Lamp tab and change

the parameters there if necessary.

3. (Do this step if you plan to use Time Acquisition or Beer’s Law

mode or the Minus Dark, Absorbance, Transmittance, or Relative

Irradiance measurements.)

a. Turn off the light source or block light from entering the spec-

trometer. Press to save the dark scan.

b. Allow “reference light” to enter the spectrometer. Press

to save a reference scan.

4. (Do this step only if you plan to use Time Acquisition or Beer’s Law

mode.) Go to the Time Acquisition tab. Set the scan mode and other

parameters as desired. (See page 6 for more information.)

5. After you have finished setting spectrometer parameters and

options, press to close the configuration screen.

See page 6 for instructions on recording and viewing data.

Spectrometer Analysis Configuration Screen

The Spectrometer Analysis Configuration screen is where you set the

parameters that control how the spectrometer and GLX collect and pro-

cess data.

To Open the Configuration Screen

• If the spectrometer is not yet connected:

Connect the spectrometer to the GLX's USB port and wait for the

configuration screen to open automatically.

• If the spectrometer is already connected:

1. Press + to open the Graph screen (if it is not already

open).

2. Press to open the Tools menu.

3. Use the arrow keys to highlight Spectrum Analysis Config.

4. Press .

What you use as the “reference light”

depends on what you plan to measure.

See see “F2 Save Ref” on page 4 for
