A sensor failure.
Excessive motion at sensor site may
be prohibiting device from detecting a
consistent pulse signal.
Animal may have an arrhythmia
resulting in some heart beats that do
not detect a pulse quality signal at the
sensor site.
Non-compatible sensor is being
used.
ECG monitor may not be functioning
properly.
ESU may be interfering with pulse

Quality of pulse signal
at sensor site is inadequate.
Replace all six batteries.
