Hardware and Software Tests
Performance Verification 25
7. Hold the
NiBP
button until the monitor displays a pressure of
approximately 250 mmHg.
8. Start 1 minute timer, and simultaneously press and hold the
ALARM SILENCE
button on the monitor.
This causes the pneumatic system to deflate at a rate of 3 mmHg/s ±1.5 mmHg/
s.
9. After 1 minute, record the pressure displayed on the monitor. The test has been
successfully completed if the monitor displays a pressure reading of 10 mmHg
to 190 mmHg.
10. Press and hold Heart Rate Tone VOLUME button until monitor displays
a pressure of 0 mmHg.
Additional NIBP tests can be performed at this time. If no further NiBP tests
are to be conducted, turn the monitor off. Normal monitoring operation
returns the next time the monitor is turned on.
Operation with a Temperature Simulator (A1 only)
1. Remove the probe from its holder.
2. Insert the calibration key in the temperature input port
T
on the A1.
3. Press the ON/STANDBY button to turn the monitor on. After the normal
power-up sequence, verify that the temperature reads 36.3 ± 0.1°C (or 97.3 ±
0.2°F).
4. Turn the monitor off.
Operation with a Temperature Simulator (A3 only)
1. With monitor off, connect the temperature cable (supplied with the temperature
simulator) to the appropriate connector on temperature simulator.
2. Connect the temperature cable to the temperature input port on the A3.
3. Set the temperature simulator as follows:
Temperature: 37°C (98.6°F)
Probe Type: YSI 400 Series
Note
The accuracy of A3 temperature measurements is ±0.1°C
(±0.2°F). In the procedure below, add the tolerance of the
simulator to the acceptable range of readings.
