2. Before inflation, vent manometer bulb to atmosphere and verify manometer reads 0
mmHg..
3. Start the monitor. Within 10 s after you hear a beep, press and hold the
button to enter the Maintenance mode. Then press the
button to display
the NIBP accuracy test interface. In the PR parameter area, the code 555 is
displayed.
4. Press the button to start accuracy test. The real-time pressure is displayed
at the top of the screen.
Pressing the
button with the test in progress will terminate the current
accuracy test. An invalid value will be displayed at the top of the screen.
5. Check the manometer values and the monitor values. Both should be 0 mmHg.
6. Raise the pressure in the metal vessel to 50 mmHg with the manometer bulb.
Then wait 10 seconds to allow the pressure to stabilize.
7. Compare the manometer values with the monitor values. The difference between
the manometer and displayed values should be ± 3 mmHg. If it is greater than ± 3
mmHg, contact Mindray Technical Support.
8. Raise the pressure in the metal vessel to 200 mmHg with the manometer bulb.
Then wait 10 seconds to allow the pressure to stabilize. Repeat step 7.
If the difference between the manometer and displayed values is greater than 3
mmHg, contact our Technical Support Department.
NOTE
 You can use an NIBP simulator to replace the manometer bulb and the
reference manometer to perform the test.
