Displays and Indicators
The following is an overview of the device's displays and indicators (figure 2). See "Visible Indicators"
on page 23 for more detailed information.
SpO
Display
2
Identified by the %SpO
oxygen saturation percentage.
This display also indicates if a pulse oximeter sensor fault or inadequate signal condition exists. If one
exists, a dash (-) appears in the leftmost position of the SpO
10 seconds, a dash appears in the middle position of the SpO
Pulse Rate Display
Identified by the
symbol, this 3-digit LED display shows the pulse rate in pulses per minute.
During a pulse oximeter sensor fault or inadequate signal condition, the pulse rate display freezes for
10 seconds and then a dash appears in the middle position of the display.
CO
Bar Graph Display

animal inhales and exhales through the airway adapter tube.
Pulse Quality Indicator
Identified by the
symbol, this tri-color LED blinks once for each detected pulse. The LED color
changes with the pulse strength signal:
• Green indicates a good pulse strength signal.
• Yellow indicates a marginal pulse strength signal. To improve signal quality, reposition the sensor,
try a different sensor type, reduce animal movement, or improve the site's circulation.
• Red indicates an inadequate pulse strength signal. While the Pulse Quality display is red, SpO
and pulse rate values are not updated. After about 10 seconds, the values are replaced with
dashes, indicating that readings are not possible.
Low Battery Indicator
Identified by the
symbol, this LED indicator is lit when battery level is low. When the batteries
reach critically low level, the display is blank and the Low Battery indicator blinks.
