Testing with the optional Masimo SET Tester
To conduct a test with the optional Masimo SET Tester
1. Turn off and then turn on the Radical-7.
2. Use the Patient Cable connector on the Radical-7 to connect the Masimo SET
Tester to the Radical-7.
3. See the directions for use that were provided with the Masimo SET Tester.
Nurse Call Test
To conduct a Nurse Call test
1. Disconnect any patient cables, sensors, or accessories from the Radical-7. Turn off
the Radical-7 and then turn on again.
2. Ensure that there are no audible alarms and that the Audible Alarm feature is not
set to silenced.
3. Verify the Nurse Call polarity is set to normal (default).
4. Connect the common lead of a digital multi-meter to the pin 12 (Nurse Call
Common) of the Analog Output connector on the Radical-7. 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 MW (open
circuit).
5. Trigger an alarm on the monitor (for example, by disconnecting a sensor after it
was measuring data). Verify that the resistance is less than 35 ohms.
Analog Output Test
To conduct an Analog Output test
1. Disconnect any patient cables, sensors, or accessories from the Radical-7. Turn off
the Radical-7 and then turn on again.
2. Connect the common lead of a digital voltmeter to the pin 2 (Ground) of the
analog output connector on the Radical-7. Connect the positive lead of the
voltmeter to pin 9 (Analog 1) of the analog output connector.
3. On the device output screen, on the analog 1 option, select 0V Output. See
Device Output on page 79.
4. Verify that the voltmeter measures a voltage of approximately 0V.
5. Change the analog 1 option to 1V Output.
6. Verify that the voltmeter measures a voltage of approximately 1.0V.
7. Repeat steps 5 and 6, with the positive lead of the voltmeter connected to pin 15
(analog 2). See Serial Interface Specifications on page 118.
8. Connect a patient cable and sensor and verify that the voltage on pins 9 and 15
are between 0V and 1.0V while measuring a saturation and pulse rate.
