Set Energy Range

The spectrometer can be set to give a variable energy range depending on the experimental requirements. To change the energy range:

  1. Set the energy range using the Dispersion setting that you can access via the (...) option in the control region of the Microscope System palette.

    1. Use a small eV/ch setting (large dispersion) for detailed spectra around an edge or the ZLP.

    2. Use a large eV/ch setting (small dispersion) microanalysis or mapping.

  2. Set energy rangeIf the exposure is set to Auto, the exposure time will automatically adjust as the energy loss is changed. This is very useful when going from a high to low energy offset. The auto feature will predict the large increase in intensity and adjust accordingly.
