Perform one of the following three SpO
2
tests.
Testing the monitor only (Nellcor SpO
2
)
Use this procedure to test only the monitor SpO
2
function.
1. Power the monitor off.
2. Connect the Nellcor SRC-MAX SpO
2
functional tester to the SpO

through a Nellcor DEC-8 extension cable.
3. Power the monitor on.
4. Verify the following on the SRC-MAX:
• All of the monitor LEDs flash: left panel, center panel, right panel.
• SRC-MAX initializes to a default condition where the four test parameter LEDs are
lit closest to their selector buttons
• The default pulse rate is 60 bpm and the default SpO
2
is 75%
5. Give the monitor up to 30 seconds to stabilize, and verify a displayed pulse rate of
60 ± 3 bpm and a displayed SpO
2
of 75 ± 3%.
6. Set the SRC-MAX pulse rate to 200 bpm.
7. Give the monitor up to 30 seconds to stabilize, and verify a displayed pulse rate of
200 ± 3 bpm.
8. Switch the SRC-MAX SpO
2
saturation percentage to 90.
9. Give the monitor up to 30 seconds to stabilize, and verify a displayed SpO
2
saturation
level of 90 ± 3%.
10. Disconnect the SRC-MAX.

The tests described in this section are to be performed only as part of a complete
functional verification procedure.
Note
In the following tests, if the SRC-MAX defaults are outside the monitor alarm
limits, readjust the limits or silence the alarms.
