Testing Each Parameter Calibration/Maintenance
2 - 14 0070-10-0591-01 Trio™ Service Manual
2.5.4 TEMP
2.5.4.1 Test Equipment
• Patient Simulator
2.5.4.2 Test Procedures
1. Connect a 400 series TEMP test cable to the TEMP connector of the Trio Monitor.
2. Connect the 400 series test cable to a calibrated Patient Simulator.
3. Set the simulator to output a temperature of 34ºC.
4. Check that the displayed TEMP value on the Trio Monitor is 34ºC +/- .1ºC.
5. Change the simulator to output a value of 40ºC.
6. Check that the displayed TEMP value on the Trio Monitor is 40ºC +/- .1ºC.
2.5.5 IBP
2.5.5.1 Test Equipment
• Patient Simulator
2.5.5.2 Test Procedures
1. Use a pressure transducer cable to connect a calibrated Patient Simulator to the Trio
Monitor.
2. Set the IBP sensitivity of the simulator to 5uv/v/mmHg, and the static IBP value to
0 mmHg. Set the IBP label to ART.
3. Perform zero calibration for IBP. Select the IBP PARAMETER menu to open the IBP
SELECT menu.
4. From the IBP SELECT menu select IBP ZERO.
5. From the IBP ZERO menu select IBP ZERO.
6. After the zero calibration is successful, return to the normal screen.
7. Set the Patient simulator to an IBP value of 100 mmHg.
8. From the MAINTENANCE menu, select IBP PRESSURE CAL.
9. From the IBP PRESSURE CAL menu, set CAL PRESSURE to 100 mmHg.
10. From the IBP PRESSURE CAL menu, select CALIBRATE.
11. After the calibration is successful, return to the normal screen.
12. Set the Patient Simulator to the following IBP static values: 40 mmHg, 100 mmHg, and
200 mmHg.
13. Check that the unit displays the following values respectively: 40± 1 mmHg, 100±
2 mmHg, and 200± 4 mmHg.
14. Set the Patient Simulator to output an arterial wave with a value of 120/80.
15. Check that the unit displays the following values: Systolic 120 +/- 2%, Diastolic 80
+/- 2%.
16. Confirm that the corresponding waveform is displayed correctly.
17. Unplug the IBP sensor. IBP SENSOR OFF should be displayed in the Message Area in
the top right corner of the display.
