3.3.5.2.1 Pressure Sensor Accuracy Test
The pressure sensor accuracy test verifies the pressure accuracy of the N5500 pressure
sensor.
1. Ensure Bio-Tek simulator is in Static pressure test mode.
2. NIBP Test screen is active on N5500, then select “Pressure Sensor Accuracy Test”
by the knob.
3. Press Select button on simulator until simulator displays “Pressure Source Set Test
Pressure”. Adjust pressure on the simulator for 250, 150, 50 and 0 mmHg.
4. Press Start Pump button on simulator. The simulator will begin to pressurize. Allow
15-20 seconds for pressure to stabilize.
5. The current pressure in mmHg will be displayed on both the simulator and N5500
displays. Ensure N5500 pressure sensor accuracy meets the performance standard of
ANSI/AAMI SP-10:1992+A1:1996 (within the specification by more than ±3 mmHg
or 2 percent of reading, whichever is greater) to successfully complete the test.
3.3.5.2.2 Over Pressure Test
The over-pressure test verifies the functionality of the over-pressure relief system.
1. Ensure Bio-Tek simulator is in Pressure relief test mode.
2. Ensure NIBP Test screen is active on N5500, then select “Over Pressure Test” by the
knob.
3. Press Start Test button on simulator. The simulator will pressurize the system until
the monitor’s over-pressure relief system activates.
4. Ensure the monitor activates over-pressure relief system at the point of protection
pressure.
Note: The test will have been successfully completed if the simulator displays a
pressure reading, approximately, of 320± 10 mmHg in adult/pediatric mode and
160±5 mmHg in neonatal mode. However, the motor’s inflation pressure speed
may cause a slight difference between over-pressure relief values in test and the
specified relief values.
3.3.5.2.3 Air Leakage Test
The air leakage test verifies the integrity of the pneumatic system.
1. Ensure the monitor is set up with Rigid cuff can.
2. Ensure NIBP Test screen is active on N5500, then select “Air Leakage Test” by the
knob.
