Although factory set (see below) the calibration gas value can be user
adjusted. When in this mode, the display scrolls the message "CAL GAS

alter the setting, or until a 3 minute timer expires, at which time the setup
modes are aborted and the unit returns to normal gas readings. If the
or
buttons are pressed during this time, the display reverts to XXXX which
indicates the newly selected value. Five seconds after the last
or
keystroke the scrolling message commences with the newly selected setting.
