SvO
2
measurement
4. Check that the SvO
2
values Meas. state, OM fail and OM temp. in the COP module service
menu all show NO OM.
5. Checks with the SvO
2
simulator:
Turn the SvO
2
simulator pulsation switch to Medium and the range switch to Normal
pulse. Connect the simulator to the module and check that the following messages
appear in the digit field for SvO
2
:
Initializing, please wait > Warming up > Not calibrated
Check that ‘Meas. state’ has changed to NORMAL and ‘OM fail’ and ‘OM temp.’ show OK.
NOTE: The ‘OM temp.’ may show UNSTABLE at first, but the message should change to OK
within a half a minute.
6. Perform an In Vitro calibration with the SvO
2
simulator.
Check that the calibration date for In Vitro calibration was updated correctly and the SvO
2
reading on the screen is 81% (±2%).

Cardiac Output measurement
7. Enter the COP module service menu.
Check the front panel
Start C.O. membrane key.
8. Enter the C.O. menu:
Others - C.O.
Connect a catheter connecting cable to the module connector C.O.
If the module contains a C.O. Test connector, attach the catheter connector of the
connecting cable to the C.O. Test connector. Check that the message ‘Cable OK’ appears
in the menu after the self-test.

2.2.15 NeuroMuscular Module, E-NMT
1. Enter the NMT module service menu:
Check that the Time-outs, Bad checksums and Bad c-s by mod values are not increasing
faster than by 5 per second. Check that the module’s memories have passed the internal
memory test, i.e. RAM, ROM and EEPROM all state OK.
2. Check the function of the front panel membrane keys
