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.
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 126.
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.
