3. Power on the monitor and verify that the SpO
2
and heart rate values are
correctly displayed.
4. Press the ALARM SILENCE button on the front panel of the monitor
to temporarily silence the audible alarm.
5. Verify that the heart rate tone source, found in the Heart Rate Menu, is set to
SpO
2
.
6. Press the Heart Rate Tone VOLUME button on the front panel of the
monitor. Within 3 seconds of having pressed the button, rotate the wheel
clockwise and verify that the beeping heart rate tone sound level increases.
7. Rotate the wheel counterclockwise and verify that the beeping heart rate tone
decreases until it is no longer audible. Rotate the wheel clockwise to return the
beep volume to a comfortable level.
3 seconds after the last button-press or rotation of the wheel, function of the
wheel reverts to moving the highlight on the display screen.
Dynamic Operating
Range
The following test sequence verifies proper monitor operation over a range of
input signals.
1. Connect the pulse oximeter tester to the monitor and turn the monitor on.
2. Place the SRC-2 pulse oximeter tester in the RCAL 63/LOCAL mode.
3. Set the SRC-2 as indicated in below. Verify that the monitor readings are within
the indicated tolerances. Allow the monitor several seconds to stabilize the
readings.
Table 4 SRC 2 Settings and Monitor Indications
An * indicates values that produce an alarm. Press the ALARM SILENCE
button to temporarily silence the audible alarm.
For the pulse rate setting of 201 bpm, the pulse rate tolerance of 195 to 207 bpm
is greater than the ±3 bpm accuracy specification of the monitor, due to the
performance characteristics of the SRC-2 tester.
4. Turn the monitor off.
