Unstable zero pressure
Explanation
Faulty RAM circuit on the CPU board.
There is no recorder module.
There is hardly any charge left in one
of the batteries. Also check the symbol
on screen.
Water trap is partially blocked. This
decreases air flow.
The sampling line inside or outside the
monitor is blocked, or the water trap is
occluded.
You are using a hose without an
automatic identification. When you try
to start the measurement, the monitor
goes automatically to the selection
NIBP Setup
- Inflation Limits.
The gas measuring sensor is
inoperative or the temperature in the
module has increased.
Signal amplitude is less than 0.4 ohms.
The finger or ear lobe may be too thin
or sensor halves are not aligned.
Faulty SRAM circuit on the CPU board.
HR is equal to or above the higher
alarm limit.
The self-check has found an error in
the temperature measurement.
Accurate diastolic pressure not
achieved because of artifacts, weak
pulsation etc.
Systolic pressure probably higher than
maximum inflation pressure, or
artifacts interfere in the systolic area.
Pressure is unstable at start of the
measurement.
What to do
•
Contact authorized service
personnel.
•
Reconnect the N-FREC or N-FCREC
module if you need a recorder.
•
Replace the battery as soon as
possible.
•
Replace the water trap.
•
Change the sampling line and
water trap.
•
Select appropriate inflation limits.
NOTE: Auto option is not available
for these hoses.
•
Contact authorized service
personnel.
•
Check connection between sensor
and patient.
•
Replace the sensor.
•
Contact authorized service
personnel.
•
Check the patient status.
