Hardware and Software Tests
22 Performance Verification
Pneumatic Leakage The pneumatic leakage test verifies the integrity of the pneumatic system.
1. Ensure that the Bio-Tek simulator is in test mode. The simulator should display
Pressure Gauge.
2. Confirm that the simulator is set up for the internal cuff.
3. Ensure that the NiBP Test screen is active on the monitor.
4. Press the Heart Rate Tone VOLUME button on the monitor.
• On the A1, this verifies that the valve is closed.
• On the A3, this verifies that both the valves are closed.
5. Perform an offset adjustment so that the simulator and monitor both display a
pressure of 0 mmHg by doing the following:
a. Press the CONTRAST button on the monitor.
b. Press the ZERO button on the simulator.
6. Press the NiBP button on the monitor to activate the pump.
7. Hold the NiBP button until the monitor displays a pressure of
approximately 250 mmHg.
8. Allow 15-20 seconds for the pressure to stabilize.
9. Record the pressure displayed on the monitor.
10. Start a 1 minute timer.
11. After 1 minute, again record the pressure displayed.
The test is successfully completed if the pressure has dropped by 6 mmHg, or
less, during the 1 minute period.
12. Press and hold the Heart Rate Tone VOLUME button until the 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.
