By using the cursor keys 

  

 the x-axis (bubble lifetime) can be zoomed 

in and out. 

 

The following measuring parameters and display options can be set (saving 

in case of starting a new measurement): 

control:

 

Either  the  bubble  "lifetime"  or  the  "frequency"  can  be 

controlled.  (For  setting  the  control  to  "frequency"  assume 

"bubble  frequency"  instead  of  "bubble  lifetime"  in  the 

following explanation.) 

bubble lifetime

 

 

/ bubble frequency

 

start:

 

Start value of bubble lifetime / frequency. 

stop: 

End value of bubble lifetime / frequency. 

factor: 

Determines the step by which the start value will be changed 

until  the  end  value    was  reached. For each step the current 

lifetime / frequency will be multiplied by this factor. 

auto clr data: 

Clear  the 

shown  data  (diagram  or  table) 

by  starting  a  new 

measurement („on“ / “off“) 

autosave:

 

Save  the 

shown  data  (diagram  or  table) 

into  the  device 

memory after the measurement is finished ("on" / "off"). It is 

useful to set “

auto clr data

” on.
