Using the M4 TORNADO Software

M4 TORNADO

Preset for measurement time

It can be set to automatic or manual,

in real or live time.

In case of stop of measurement by number

of counts, the energy region has to be set

separately.

Settings for cyclic acquisition

For cyclic measurements the number of

cycles and the pause between them can

be set. An automatical saving of spectra to the

project is possible.

Fig. 20 Settings for spectrum acquisition

To start a spectrum acquisition, click the button. A second click will terminate the

measurement independent of the timing mode chosen. If a preset timing condition is reached, the

acquisition will stop automatically.

During the acquisition a progress bar is displayed. The scaling of the bar depends on the chosen

timing option. With fixed and automatic timing a linear scale is provided. With manual timing the

estimated precision according to the count statistics is used as an indicator. The green range

spans a statistical error of about 5 % to 0.1 % absolute deviation. This allows flexible timing

according to the purpose of the analysis.

6.3.2 Spectrum display and manipulation

Spectrum name. As soon as the acquisition is started the settling spectrum is displayed in the

spectrum window and a new entry is added to the spectrum list below. The default spectrum

name is “Acquisition” or a name referring to the associated object. If a spectrum with this name is

already contained in the spectrum list, it is automatically overwritten (automatic numbering can be

selected, multiple objects in Objects mode and standard samples are always numbered

consecutively).

Change the default spectrum name into a unique name to prevent the spectrum from being

overwritten.

Multitasking. During spectrum acquisition other tasks such as loading stored spectra, creating

and processing a report, setting up methods and spectra quantification can be executed within the

current workspace.
