Monitoring in Spectral Aquisition

Monitor mode allows to preview sample spectra prior to actual measurement. Monitor mode is critical for preparing the sample and optical system for subsequent measurement.

Time

There is no definition of time in Monitor mode. Status bar will display time elapsed since monitoring has started.

Monitor mode continues indefinitely until stopped.

Parameters

Monitor mode uses all the same acquisition settings as measuring modes. The only difference is that Monitor mode use static initial values. It will not apply such dynamic factors as increasing in cycle duration, delays etc.

Hardware

Monitor mode does not use any hardware other than probe light Shutter. No exposure, temperature ramping etc. will occur in Monitor mode.

Data flow

In the Monitor mode, spectra are always displayed in the Display plot, while in Acquisition modes displaying data can be suspended to reduce overload. Once data are acquired and displayed they are discarded.

Notes

With very few exceptions, it is highly recommended to observe several spectra in the monitoring mode prior to any acquisition. In most cases it is also necessary to observe unprocessed (raw) data in Monitor mode and perform optical alignment.
