Analog Output Test
1. Disconnect all patient cables and sensors from the Radical. Turn the Radical off
and then on again.
2. Connect the common lead of a digital voltmeter to the pin 2 (Ground) of the analog
output connector on the Radical. Connect the positive lead of the voltmeter to pin 9
(Analog Out - % SpO
2
) of the analog output connector.
3. Enter the menu system and set the "Output", "Analog Output Mode" to "0V Signal".
Verify that the voltmeter measures a voltage of approximately 40mV.
4. Enter the menu system and set the "Output", "Analog Output Mode" to "1V Signal".
Verify that the voltmeter measures a voltage of approximately 980mV.
5. Repeat Steps 2 and 3, with the positive lead of the voltmeter connected to pin 15
(Analog Out - Pulse Rate).
6. Connect a patient cable and sensor and verify that the voltage on pins 9 and 15 are
between 0V and 1V while measuring a saturation and pulse rate..
Battery Test
1. Fully charge the Radical pulse oximeter by placing the Handheld into the Docking
Station and connecting the AC power (the AC mains switch must be on).
2. Verify that the green Handheld Battery Indicator LED is lit up.
3. When the Radical is fully charged the green Handheld Battery Indicator turns off.
4. Turn the Radical on and verify that the Battery indicator shows a full charge.
