SpO
and Pulse Rate Displays
2
A pulse oximeter sensor fault occurs if the 9847V pulse oximeter detects a sensor disconnect,
dislodgement, or failure.
If a pulse oximeter sensor fault occurs or a sensor signal is no longer detected, a medium
priority (equipment) alarm starts. A dash ( - ) appears in the left digit of the SpO
and the displayed readings freeze for 10 seconds if the sensor fault or inadequate signal
continues. During this medium priority alarm, an audible indicator occurs.
If the sensor fault or inadequate signal is not corrected, dashes display in the middle digit
of both the SpO
and pulse rate displays 10 seconds after the first dash appeared. The
2
corresponding dash(es) blink if there was a prior high priority animal alarm. When the
sensor fault or inadequate signal is corrected, the SpO
normal operation.
When the SpO
or pulse rate alarm limits are met or exceeded, a high priority animal alarm
2
condition exists. The numerical values of the corresponding parameter blink and an
audible alarm occurs. If either the SpO
latched (continue) and the oximeter enters the critical battery state, the parameter will
show 3 blinking dashes in the corresponding displays.
If latched for a pulse oximeter medium priority equipment alarm (a sensor fault or inadequate signal),
a single blinking dash displays in the corresponding middle digit of the SpO
The visible and audible indicators stop when the condition is cleared.
Alarm Limit Review
When the Alarm Limit Review button is pressed and held, the animal alarm limits in effect
for no breath delay time (in seconds), SpO
pitch setting, display in sequence for approximately 2 seconds in the order and format
shown in Table 3. If the button is released, the review mode is exited and normal operation
resumes.

During the alarm limit review only the SpO
and pulse rate measurements display after completing the limit review. If a critical battery state exists,
the alarm limit review sequence does not appear.
NOTE: Pressing and holding the Alarm Limit Review button can be used to review alarm limits
and to activate an event marker.
