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 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
minutes ("time out").
