Spectrum view when

measuring

The Main Spectrum graph on the display (the one with bars) is selected using the parameter

selector on the second line of the two shown above the graph (LZF in Fig.14.8). The smileys

below the spectra (if there are any) belong to the Main Spectrum. The parameter selector for

the Main Spectrum is linked to the selector on the Overview tab and the parameter selector for

the main decay on the Decay tab.

The reference spectrum on the display (the one displayed as small lines above the bars in

Fig.14.7) is selected using the parameter selector on the first line of the two shown above the

graph (T30 in Fig.14.7). The parameter selector for the reference spectrum is linked to the

parameter selector for the reference decay curve in the Decay view.

The cursor is linked to the Frequency selectors on the Overview and Decay tabs.

Tap the Y-axis to select:

• Auto Zoom to adjust the range of the Y-axis for best fit of the measured spectrum

• Zoom In/Zoom Out to adjust the zoom

• Spectrum Table to display the spectrum in a table, see an example in Fig.14.9
