Displayed Internal Event Log Description
Device Code
E11 > 10mm residual pressure > minutes.
E11 >15mm residual pressure >3 mins.
C02 Couldn't bleed pressure < 9 mmHg
Termistor pulled away from the tip or
heater broken.
Probe not responsive. Probe not
characterized/calibrated.
Probe not characterized/calibrated.
C06 Low inflation; first step had largest value,
first step's value > systolic value.
C06 Dump too soon; last step had largest
value, next to last step's value > diastolic
value; will not normally occur in auto-
dump mode.
C05 Step too big systolic; difference in
pressure between step above and step
below systolic is too great.
C05 Step too big diastolic; difference in
pressure between step above and step
below diastolic is too great.
C05 Range error: calcualted BP is outside of
measurement range.
C05 Pressure reverse systolic; pressure of step
above systolic is lower than pressure of
step below systolic.
C05 Pressure reverse diastolic; pressure of
step above systolic is lower than pressure
of step below diastolic.
C05 Step too big MAP; difference in pressure
between adjacent steps near MAP is too
great.
C05 Too few steps; less than 5 steps
C05 Bad value diastolic; value of step below
diastolic and step below that step are not
consistent.
C05 Value reverse systolic; value of step above
systolic is greater than value of step
below systolic.
C05 Value reverse diastolic; value of step
above systolic is greater than value of step
below diastolic.
Troubleshooting
Corrective Action
Verify that the supply voltage is within
specification.
Verify that the supply voltage is within
specification.
Auto zero failure, check tubing for kinks
and connection integrity, limit patient
movement.
Try another predict cycle. If the problem
persists, replace probe.
Replace probe.
Replace probe.
Measurement was outside of Spot Vital
Signs LXi measurement range.
Check connections; restrict patient
movement.
Excessive noise; check cuff placement and
limit movement.
