5  User Interface 

The KSR-V uses a graphical LC display  with automatic backlight for showing the measurement values and 

the device settings.  

The  device  provides  4  keys  to  the  user  to  accept  any  inputs.  The  action,  a  key  performs,  depends  on  the 

actual context and  is given by small icons in the bottom line of the display. This means a much more easy 

and intuitive usage of the device, even in complicated situations and settings. 

5.1  Main menu 

The  main  menu  is  the  central  point  of  menu  navigation.  Here  you  can  directly  enter  all  submenus  or  the 

measurement display. 

The main menu shows the following menu items for configuration or measurement display: 

 

measurement

 = display measured values

 

 

auto-roll = 

display measured values with automatic value rotation

 

 

harmonics 

- This submenu shows the single harmonics for all input channels 

 

 

setup 

- The device settings can be found inside this submenu

 

 

device info 

-

 

This submenu shows some information about the device

 

 

reset min/max = 

reset minimum/maximum values

 

 

KEYS: 

The  user  can  navigate  through  the  menu  entries  by  use  of  the  "

"  and  "

"  keys.  On  the  left  side  of  the 

topmost item, a tiny arrow ( ">" ) shows which item is actually selected. By pressing "

", one can enter into 

the selected submenu. The left key is not used in the main menu. 

 

After  connecting  the  supply  voltage  the  device  automatically  starts  with  the  submenu 

"measurement"! 

Whenever  a  capital  "M"  is  used  as  key  symbol  in  any  sub-menu,  pressing  the  key  will 

switch straight to the main menu.
