3000 Oxygen Monitor
Section 1, Introduction
The operator can silence the audible alarm for
three 30-second intervals for a total of 90 seconds;

the end of the silence period, the audible alarm
reactivates if the alarm conditions is not corrected.

Low Battery Alarms
The MiniOX
®
3000 Oxygen Monitor features a two-
stage battery alarm that warns of depleted and
expired battery voltage:
•
7KH¿UVWDODUPDOHUWVWKHRSHUDWRUWKDWWKH
monitor has approximately six hours of
operating time remaining:
• a warning message appears in the display
• an audible alarm sounds at 30-second
intervals
• If the operator does not replace the battery
after this alarm, a second low battery alarm
activates when the battery is no longer able to
support monitoring. The monitor:
• displays a warning message
• activates an audible and visual alarm (
See
Section 3, Low Battery Alarms
)
Sensor Indicator
During monitor, the MiniOX
®
3000 Oxygen Monitor
displays a warning message; audible and visual
alarms activate if:
• the oxygen sensor becomes disconnected
• the cable fails or disconnects from the sensor
or instrument
• the sensor membrane is perforated
• the thermistor circuit opens

• following sensor disconnection/reconnection.
If a calibration is performed using a calibration
gas other than room air or 100% oxygen, or if the
microprocessor detects a calibration error during
normal operation:

connected is turned ON, the monitor performs a self-
test and a calibration requirement occurs.

operator to carry out the calibration procedure.
The calibration procedure is initiated by exposing the

oxygen concentration of 20.8%) or 100% oxygen] and
pressing the corresponding key on the keypad. The
following appears on the display:
•
• the selected calibration gas concentration.
When the key is pressed the monitor displays:
• “CAL”
• a 10-segment bar graph which “counts down”
two seconds per bar for 20 seconds.
The monitor automatically calibrates to the selected
concentration. At the end of the 20 seconds, the
monitor:
• emits a beep indicating that calibration is
complete
• enters the operating mode
See Section 3, Calibration
Low/High Oxygen Concentration Alarms
The MiniOX
®
3000 Oxygen Monitor has audible
and visual alarms that activate when oxygen
concentrations exceed preset low or high alarm
settings. Default settings are 18% and 50%,
respectively.
When the MiniOX
®
3000 Oxygen Monitor detects an
oxygen concentration that exceeds the preset alarm
limit:
•

• an audible alarm activates
• the measured concentration appears in the
display
