3.3 Functional check
Turn the monitor on. Wait until the normal monitoring screen appears.
3.3.1 Test setup
Required tools
− P/N: N-ES or Simulator for E-ENTROPY
−
Entropy sensor cable
NOTE: See the supplemental information manual delivered with the manual for compatible
accessories.
Connections
•
Ensure that the module is connected to the monitor.
Monitor configuration
1. Configure the Entropy waveform field to the monitor screen with adequate priority.
2. Press the Entropy module key in the module to open the Entropy Setup menu
and configure:
Scale : 250uV
Display format : RE+SE
Automatic sensor check : ON
3.3.2 Entropy tests
1. Module and sensor recognition
a.
Connect the Entropy sensor cable to the module.
b. Check that the Entropy EEG waveform field and related information appears to the
screen.
c. Check that a 'No sensor' message is shown in the Entropy parameter window.
2. Sensor checking
a.
Connect the Entropy simulator to the Entropy sensor cable.
b. Check that a 'Checking sensor' message appears to the Entropy parameter window
after a while and wait until all 3 electrodes are checked. The sensor check is passed,
if a green circle with a check mark for each tested electrode is shown.
NOTE: The monitor may show messages ‘not an Entropy sensor’ and ‘Demo data’. These
messages are normal for the Entropy simulator.
3. Functional check with a simulator
a.
Check that the EntrEEG waveform and RE & SE values appear on the monitor screen
approximately 30 seconds after the sensor check is completed.
3.3.3 Test completion
Select Discharge patient or Reset case to discard any changes made to the monitor
configuration during checkout.
