•Remove the module from the frame and plug it back again. Then perform  “Calibration 
check”  (see the preceding page) to verify the new calibration.
3.4.2 Temperature calibration
NOTE: For the temperature calibration, separate, accurate test plugs (25 °C and 45 °C) are 
needed. A test set of two plugs is available from GE Healthcare, order code 884515-HEL. 
A Dual temperature adapter cable, order code 2016998-001 is also required for the 
temperature calibration. 
Calibrate the temperature, when the measured test values differ for more than ±0.1 °C, and 
always after STP board replacement .
1. Enter the STP service menu. 
(
Monitor Setup - Install/Service  (password 16-4-34) -  Service (password 26-23-8) - 
Parameters ).
2. Enter  Calibrations  menu.
3. Choose  Protection OFF  in protect mode. 
4. Select  Calibrate T1/Calibrate T2 .
5. Insert calibration plug ( 25 °C) into T1/T2 connector.
6. Push the ComWheel.
7. Insert calibration plug ( 45 °C) into T1/T2 connector.
8. Push the ComWheel.
9. Choose  Protection ON  in protect mode. 
3.4.3 Invasive pressure calibration
NOTE: Before starting invasive pressure calibrati on, disconnect all patient cables and discharge 
the patient.
NOTE: For the Invasive pressure calibration a Dual InvBP adapter cable, order code 
2005722-001, is needed.
Calibrate the invasive pressure when the pressure transducer (probe) is replaced with a 
different type of transducer, and when the STP board is replaced.
1. Enter the STP service menu.
(
Monitor Setup - Install/Service  (password 16-4-34) -  Service (password 26-23-8) - 
Parameters ).
2. Enter  Calibrations  menu.
3. Connect a pressure transducer with a pr essure manometer to the P1/P2 connector. 
Choose Calibrate P1  or Calibrate P2 . Leave the transducer to room air pressure.
4. Push the ComWheel to start zeroing.
5. Supply a pressure of 100 mmHg to 300 mmHg to the transducer. The recommended  pressure is 200 mmHg.
6. Set the pressure on the display to match the pressure reading on the manometer and  push the ComWheel. A tolerance of ±1 mmHg is allowed.
7. The message ‘Calibrated’ will be displayed on the display.

4.1 Troubleshooting charts
See also the “User’s Reference Manual” for more troubleshooting procedures.
4.1.1 NIBP
ProblemCause What to do
No NIBP value displayed NIBP not selected on screen. Check monitor setup.
NIBP menu fading No E-PSM(P) module, module not 
properly connected. Plug in the module.
‘Artifacts’ message Unsuccessful measurement due to  patient movement, shivering, 
external artifact or weak signal. Check the patient status.
‘Weak pulsation’ message Weak or unstable oscillation pulses  due to:
•artifacts 
•weak pulse pressure due to 
arrhythmias
•improper cuff position or 
attachment
•too few pulses detected
•weak or unusual blood 
circulation
•obese patient Check patient condition and retry.
Check any leaks and retry.
Use proper size of cuff. Check 
attachment.
Call service
‘Error X’ message NIBP hardware error.
X = error number. See the description of the error message 
code, the causes and the solutions listed 
in the 
“NIBP error code explanation”  
chapter.
‘Cuff loose’ message 1. Hose and/or cuff not  connected. 1. Connect the hose and the cuff.
2. Hose and cuff connected.  Reasons:
- cuff loosely wrapped - Tighten the cuff.
- leakage inside the shield, in the  Patient connector panel or 
tubings connecting to the 
module - Check the tubings inside the shield 
and Patient connector panel, fix if 
necessary.
- leakage in cuff or hose - Replace cuff/hose.
- leakage inside module - Check internal tubing and fix if 
necessary.
- pump does not work - Check pump connector; if OK, 
replace the NIBP Pump Unit.

Document no. M1215098-002
Cuff ID not working 1. Defective cuff ID holes in the 
NIBP cuff hose - Replace NIBP cuff hose.
2. NIBP flex board connector  wrongly connected - Check that the NIBP flex board 
connector is properly connected to 
the STP input board: all pins have to 
be connected.
3. Cuff ID switches defective - To  check the switches, attach a NIBP 
cuff hose without the cuff ID and 
check that the message ‘Select 
inflation limit’ appears. If not, replace 
the Front Panel Unit.
4. NIBP ID switch cable (between  patient connector panel and the 
module) broken or poorly 
connected  - Check the cable, fix if necessary.
‘Air leakage’ message 1. Hose or cuff leaking. Reasons: 1. Replace cuff - cuff damaged - Replace cuff.
- cuff connector damaged - Replace cu ff connector (if the fault is 
in hose connector).
- O-ring damaged or missing - Replace O-ring.
- hose double connector damaged - Replace NIBP cuff hose.
2. Hose and cuff OK. Reasons: 2.   Connect or replace tube
- leakage in the tubes connecting  the patient connector panel and 
the module - Check the tubes.
- leakage inside the module - Replace the whole tubing.
- tube disconnected or damaged - Fix connections.
- manifold leaking - Replace the manifold.
- tubes or valve(s) damaged - Replace tubes/valve(s).
‘Unable to measure Sys’ 
message Systolic blood pressure probably 
higher than the inflation pressure or 
artifacts. Automatic retrial with increased 
pressure.

‘Cuff occlusion’ message 1. Cuff and/or hose occluded. Reason:
- cuff tube kinked - Straighten tube.
- tubes inside the shield kinked - Straighten tubes.
- tubes inside module kinked - Straighten tubes.
- occlusion inside/outside module - Remove occlusion.
2.  Cuff, hose, and tubes OK. Reason:
- fault in pressure transducer - Replace the NIBP board.
- fault in A/D converter - Replace the NIBP board.
- faulty calibration - Check calibration.
‘Calibration switch on’ 
message EEPROM protection has been 
handled by pressing module buttons
 
Auto ON/OFF 
and Start/Cancel 
simultaneously for 3 seconds. Enables setting the protection OFF in the 
Calibration
 menu. Press the buttons 
again if you are not going to calibrate.
