The "Back" and "Meas" keys located under the numeric keypad are designat-
ed as cancel keys.
The "Back" key allows the operator to cancel a function or menu item and
return to the previous menu level.
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

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
minutes ("time out").
