Introduction MX300-I

The oxygen level is calculated and then displayed on the liquid crystal display (LCD) on the front panel.

In the MX300-I monitor, user-programmed high and low alarm set points are stored in random access memory (RAM), which resides within the microprocessor. The oxygen level calculated by the microprocessor is compared to these set points, and an alarm activated, if necessary.

The audio alarm is used for both the concentration alarms and the sensor disconnects alarm. The user can manually bypass the concentration alarm for a set amount of time. Pressing the ALARM SILENCE key () will provide an audible alarm override for 115 seconds. After that, if the alarm condition still prevails, the audible alarm will resume. The ALARM SILENCE key () can also be used to interrupt the sensor disconnects audible alarm.
