In the measuring mode the display shows the preselected measured values and all 4 pushbuttons have the
function printed on them. The switch over between the different measuring displays and the error display can be
made at any time without interrupting the measurements.
In the control mode the 3 pushbuttons below the display have varying functions. The actual function is indicated in
the display, just above the pushbutton.
In the control menu all necessary settings can be made.
The control menu contains the 5 submenus “ZERO OFFSET”, “DISPLAY”, “SETUP”, “I/O-TEST” and “SERVICE”.
For protecting the unit against unintentional changes by unauthorized personnel, the menus “ZERO OFFSET”,
“SETUP” and “I/O-TEST” are protected by a user password and the menu “SERVICE” by a service password.
For the description of the control menu see chapter 4.5.
