Softkeys
The six buttons under the screen and the softkey line at the
lower edge of the screen are known as softkeys.
A softkey is the combination of the button and its designation in
the softkey line.
A softkey does not have any set function, but is assigned a
function for a given situation as shown in the softkey line of the
screen.
Pressing a softkey is the equivalent of pressing the button
assigned to the function; this process is illustrated by the quasi-
three-dimensional softkey representation on the screen.
Softkeys are also called buttons in this operating instruction.
Softkeys in Measurement Mode
In measurement mode, the softkey line contains the ‘
MENU

‘
>>
’ softkeys.
The ‘
STATUS MESSAGE
’ softkey also appears if an error occurs.
