Global functions apply to all spectral windows in OOIBase32.
Store Global Dark
This option stores the current spectra as dark spectra for all spectral windows in OOIBase32.
Take the dark spectrum with the light source off or with the light path blocked. You must save a dark
spectrum before the computer can make the calculations of absorbance, transmission, and relative
irradiance spectra. Additionally, you must use the Save Dark command to permanently save the dark
spectrum to disk.
Click on the Store Global Dark icon (
) or select Spectrum | Global | Store Global Dark.
Store Global Reference
-
This option stores the current spectra as reference spectra for all spectral windows in OOIBase32.
Take a reference spectrum with the light source on and a blank in the sampling region. You must save a
reference spectrum before the computer can make the calculations of absorbance, transmission, and
reflection spectra. Additionally, you must use the Save Reference command to permanently save the
reference spectrum to disk.
Click on the Store Global Reference icon (
) or select Spectrum | Global | Store Global Reference.
Global Snapshot
-
This option freezes the data acquisition for all spectral windows in OOIBase32 and allows you to
continue to view a single set of spectra.
Click on the Global Snapshot icon (
) or select Spectrum | Global | Global Snapshot.
Global Emergency Reset
-
Use this command to reset all acquisition parameters for all spectral windows in OOIBase32.
In some cases, a chosen set of acquisition parameters could take an extremely long time to complete a
spectral acquisition (for example, a 10,000 msec integration time with 1000 averages). Selecting this
