4) Do either of the following as appropriate:
a If using variable simulator, change oxygen saturation value and
verify that pulse tone frequency (pitch) increases as SpO
increases, and decreases as SpO
b If using pocket tester or equivalent, replace tester with adult finger
sensor and place sensor on your finger. Your SpO2 reading should
be > reading obtained from tester, and frequency (pitch) of pulse
tone should increase.
1) In Alarm Limits Table, set SpO
80%, and assure that alarm is ON.
2) Set simulator to an SpO
3) Verify that monitor responds with serious Alarm indication.
4) Reset simulator to value within alarm range. Verify that alarm ceases
Using the Temperature Y Cable input to the MultiMed Pod, set up the
patient simulator to supply a temperature input to Temp A.
Set the simulator for a standard 37°C.
1) Verify that monitor indicates temperature of 37±0.1°C.
2) Change simulator to temperature above and then below 37°C.
3) Verify that monitor readout agrees with simulator settings ±0.1°C.
4) Repeat procedure for Temp B input to Temperature Y Cable.
Use the following procedure to check temperature calibration. Record and
retain results in a copy of Table 4-2. Also record results in Appendix D.
Monitor must be returned to Siemens for repair if calibration check fails.

1) Connect MultiMed cable to input of patient monitor.
2) Connect temp "Y" cable to temp input of MultiMed Pod.
3) Connect decade resistor to Temp A temperature input.
4) For each resistance value in Table 4-2, verify that monitor reports "Set
Temperature" value ±0.1°C.
5) Repeat procedure for Temp B input to Temperature Y Cable.
