THE USER INTERFACE

Figure: 4 – Display

Display and keyboard layout

The user interface consists of a rectangular display surrounded by push buttons.

The display has two main modes: the measurement display (HOME screen) and the menu dis-

play.

The instrument will start up with the measurement display shown. The display area is divided

into four areas: a large main display in the middle, an icon row at the top, a message or cap-

tion field underneath and an icon row at the bottom.

Measurement display

Here the last measured Rl value is presented with large digits together with other information.

On the graphic above, all possible information is shown in the display. If a function is deac-

tivated, it will not be shown. The actual date and time is always shown.

Upper icon row

The upper row of icons is accessed by pressing the UP button ▲. One of the icons is then

highlighted (inverted) and can then be activated by pressing the OK button. The other icons in

the row can be accessed by using the LEFT ◄ or RIGHT ►buttons. The meanings of the icons

are (from left to right):

 Series ID (name) selection.

 User ID (initials) selection. Can be switched off (see pg. 21).

 Error/warning alarm. Will be shown in case of an error/warning (see pg. 39).

 GPS indication (see pg. 26).

 Battery status (see pg. 43).
