View Menu: Auto scale Y-axis 

 

By using this option, the graph will be rescaled on-line. A maximum signal will be shown at about 
75% of the vertical scale. This will be realized for all channels in the current view mode. 

 

View Menu: Goto Preset Scale 

 

By clicking this menu option,  the scale for X- and Y-axis will be set to a range that has been set 
before . The same result can be achieved by clicking the Goto Preset Scale Button in the button bar. 

 

View Menu: Grid Enable 

 

With the Grid Enable option activated, a grid will be displayed in the graph as shown in the figure 
below.  

 

View Menu: Progress Bar Enable 

 

If using long integration times or a high number of averages, it can take a few or more seconds 
before a new scan is received by the application. To get an indication about how much time it will 
take until the next scan arrives, a progress bar can be displayed. After enabling the progress bar by 
clicking the menu option, it will be displayed after the next scan has arrived. The progress bar will 
be shown only if the time between scans is more than one second. The time between scans is 
roughly the integration time, multiplied with the number of averages. However, if the number of 
averages is high, the time between scans can get longer because of the overhead time that is spent 
on transmitting the high number of average spectra to the PC.
