Using the 9847V Pulse Oximeter
Critically Low Battery Alarm
The audible critically low battery alarm is a medium priority equipment alarm indicating the batteries
have reached a critically low level and must be replaced immediately. The 9847V will not monitor
animals after the batteries reach a critical power level. Also during this medium priority alarm, the
visible Low Battery indicator blinks.
If a high priority animal alarm condition exists before reaching critically low battery level, the audible
and visible alarms “latch.” A “latched” animal alarm condition sounds a high priority animal audible
alarm. A high priority animal visible alarm indicator that is “latched” for a critically low battery will either
blink (for no breath or pulse quality) or display 3 blinking dashes (for SpO
2
or pulse rate).
The audible critically low battery alarm cannot be disabled by the alarm disable switch.
SpO
2
High or Low Alarm
The audible SpO
2
alarm is a high priority animal alarm that sounds (if the audible alarms are not
disabled) when the SpO
2
high or low alarm limits are reached or exceeded. (Also during this high
priority alarm, a visible alarm occurs. See “SpO
and Pulse Rate Displays” on page 24 for more
information.) The audible and visible indicators stop when the condition is cleared.
Pulse Rate High or Low Alarm
The audible pulse rate alarm is a high priority animal alarm that sounds (if the audible alarms are not
disabled) when the pulse rate high or low alarm limits are matched or exceeded. (Also during this high
priority alarm, a visible alarm occurs. See “SpO
and Pulse Rate Displays” on page 24 for more
information.) The audible and visible indicators stop when the condition is cleared.
Pulse Quality Alarm
The audible pulse quality alarm is a high priority animal alarm that sounds (if the audible alarms are
not disabled) when the detected pulse signals are of inadequate pulse quality. During this high priority
alarm, the Pulse Quality indicator blinks red as it normally does in inadequate pulse quality situations,
and can be latched (will continue) for the critical battery state. (See “Pulse Quality Indicator” on page
25 for additional information.) The audible and visible indicators stop when the condition is cleared.
CAUTION:
The critically low battery state overrides the audible alarm disable switch.
If a critically low battery condition occurs and the audible alarms are either
temporarily or permanently disabled, the audible alarms will become re-enabled. A
medium priority alarm will sound unless there is a high priority alarm condition in
effect. The Audible Alarm Disabled indicator will not be lit.
