Alarms 45, 46, 63, 64, 66 are only meaningful when the auto-calibration option is being used.
The value of the four oxygen level alarms, 40 to 43 can be set by the user.
3.8.2 Display of Alarms
When an alarm occurs it is shown on the display. This can take two forms. As the analyser is
supplied the decimal point will flash. This indicates that there is an alarm condition. The analyser
can be set to display the parameter numbers of the relevant alarms. To do this parameter 44 is
set to zero.
