AMA 310/UMS V21.0 

Chapter 5 

 

Menu Structure 

The instrument works in a clearly arranged menu structure. The individual menu items are to be 

selected  by  so-called  soft  keys  (

F1

...

F5

).  A  menu  page  may  include  up  to  five  menu  items.  In 

addition, the menu includes further menu pages. By the menu items 

>>>

 and/or 

<<<

 it is possible 

to scroll forwards or backwards in the menu. By 

BACK

 you get back to the previous menu. 

 

Every measuring range has its own menu, which is adapted to the relevant operating mode. For 
easier operation, the composition of the range menus adapts to the current operating condition of 

the measuring receiver. This means that different menus appear in the basic state and when the 

instrument is tuned. 

 

Apart  from  that  after  pressing  the  keys 

ANALYZ 

(for  Analyzer), 

PRINT

  and 

MODE

,  further 

independent  main  menus  appear  which  additionally  structure  the  scope  of  functions  of  the 
instrument. 

 

The keys 

RANGE

, 

ANA/DIG

, 

LNB

, 

RECALL

 and/or 

SAVE

 have no function in AMA 310/UMS. 

 

Via the key 

HOME

 the measuring receiver is reset to the basic state.  

 

The functions of the 

MODE

 key are only available in the basic state of the instrument. 

 

For the subsequent chapters the following notation is used for describing the menu navigation: 

 

KEY

 

→

 

Menu Item Main Menu

Menu Item Submenu

 

…. 

 

 

Example: The change of the menu language from English to German in the basic state is done via: 

 

MODE

 

→

 

LANGUAGE

 

→ 

GERMAN

 

 
The following figures illustrate the process:
