Only entries confirmed with the ENTER key are stored; unconfirmed items
are not accepted.
The "Back" key also allows the operator to clear gas analyzer help text and
messages.
The "Meas" key allows the operator to cancel a function or menu item and to
return to the measured value display in measurement mode.
Only entries confirmed with the ENTER key are stored; unconfirmed items
are not accepted.
NOTE
The gas analyzer automatically reverts to the measurement mode to display
values if the operator has not pressed a key in menu mode in the last five

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 key assigned to the func-
tion; this process is illustrated by the quasi-three-dimensional softkey rep-
resentation on the screen.
Softkeys are also called keys in this operating instruction.
