Troubleshooting
10-3
Check NIBP NIBP measurement affected by low
blood pressure and pulsation, or a
change in patient's condition.
• Check the patient status.
• Check the measurement setup.
• Check the cuff.
Check sample gas out Sample gas outlet is blocked.
• Remove blockage from the sample
gas outlet.
Check SpO2 probe SpO
2
: There is no detectable SpO
2
signal, the sensor is faulty or it is
detached from the patient.
• Check the sensor and connections.
Cuff loose Cuff is not attached to the patient or it
is too loose. The hose is not connected
to the module.
• Check cuff and hose.
Cuff occlusion Tubes or hose are kinked.
• Check tubes and hose.
Cuff overpressure Cuff is squeezed during measurement
and pressure safety limits are
exceeded.
• Check cuff, hose and tubes.
• Restart measurement.
measurement off Leads have been disconnected for 15
minutes for impedance respiration
check or have just been connected
(<15 seconds ago).
• Reconnect the leads or wait to
continue the measurement.
EEPROM error or EPROM error Faulty EEPROM circuit on the CPU
board, or failure in CPU software
memory.
• Call service to replace CPU.
Faulty ECG cable The ECG cable is defective.
The ECG cable may be electrically
damaged or the connectors are wet.
• Change the ECG cable and the lead
set.
• Change the ECG module if the
module connector is wet. Keep the
connectors dry.
• Avoid excessive use of liquids when
cleaning cables and connectors.
Gas measurements removed
• Reconnect the N-FREC or N-FCREC
module if you want to restart the
CO
2
measurement.
Identical modules There are two identical modules
measuring the same parameter.
• You are trying to use two or more
E-PSM(P)W modules or two or more
N-Fx modules at the same time.
You can only use one E-PSM(P)W
and/or one N-Fx module at a time.
Remove extra modules.
Infl. limits! Check setup Adult or child cuff is used but infant
inflation mode is selected.
• Check cuff and inflation limits.
InvBP’s not zeroed One or both InvBP channels have not
been zeroed.
• Zero the channel indicated or zero
both channels.
