continuous spectrum analysis

Well... I accidentally hit the continuous spectrum analysis button instead of timed spectrum.  How long does this last? Say a max of 24 hours but can't find info on how long it runs.

From the guide: "When choosing Start Continuous Spectrum Analysis, the scan is run continuously for 24 hours, or until stopped manually (using the Stop Spectrum Analysis button)."

The classical example of a continuous spectrum, from which the name is derived, is the part of the spectrum of the light emitted byexcited atoms of hydrogen that is due to free electrons becoming bound to a hydrogen ion and emitting photons, which are smoothly spread over a wide range of wavelengths; in contrast to the discrete lines due to electrons falling from some bound quantum state to a state of lower energy.
