Structure of the menu
Each menu (see
Menu Overview
on page 113) from the main
menu contains a maximum of three menu items (‘3-tier menu’).
Each menu item is assigned to one of three buttons
 ,  and  ,
therefore each menu item can be selected directly. The  button
is always used to return to the next higher menu.
The most commonly needed functions are arranged in the menu
in a way that they can be called up by pressing each of the keys
repeatedly:
‘  Operation /  Calibration /  Manual Calibration /
 Zero point / Single point’
‘  Setup /  Calibration Data /  Test gas set points’
‘  Maintenance /  Diagnosis /  Device status /  Status
