service/maintenance

Testing with Masimo SET Tester (Optional):

1. Turn the Radical off and then on again.

2. Set the alarm limits to:

3. Connect the Masimo SET Tester to the Patient Cable Connecter.

4. Verify that within 20 seconds a plethysmographic and a Signal IQ waveform displays.

(may require the Radical to be set to the Pleth and Signal IQ display setting).

5. Verify that the SpO

measurement is between 79% and 84%.

6. Verify that the pulse rate measurement is between 55 bpm and 65 bpm.

7. Verify that an audible alarm occurs and that the SpO

measurement and the low

SpO

alarm are flashing

8. Press the Alarm Silence button once and verify that the alarm is silenced.

9. Wait 120 seconds and verify that the alarm silence times out and the audible alarm

is activated again.

10. Press the Increase Loudness button several times and verify that the loudness of

the pulse beep tone increases.

11. Press the Decrease Loudness button and verify that the loudness of the pulse

beep tone decreases. Press the Decrease Loudness button and verify that the

Nurse Call Test:

1. Disconnect the patient cable or the Masimo SET Tester from the Radical and turn

the instrument on. Ensure that there are no audible alarms and that the audible

alarms are not silenced.

2. Connect the common lead of a digital multi-meter to the pin 12 (Nurse Call -

Common) of the analog output connector on the Radical. Connect the positive lead

of the multi-meter to pin 6 (Nurse Call - Normally Open) of the analog output

connector and measure that the resistance is greater than 1 M

Ω

(open circuit).

3. Trigger an alarm on the monitor (e.g. by disconnecting a sensor after it was

measuring data) and verify that the resistance is less than 35 ohms.
