T-shape connector
Air tubing
Balloon pump
Rigid vessel with volume 500±25 ml
Standard manometer (calibrated with accuracy greater than or equal to 0.75 mmHg)
Follow this procedure to perform the test:
1. Connect the monitor and the test tools as shown below.
2. Before inflation, check whether the reading on the manometer is 0. If not, open the valve of the balloon pump to let
the whole airway open to the atmosphere. Close the valve after the reading becomes 0.
3. Select
Main Menu→ System →Maintenance >> Module → NIBP →NIBP Accuracy Test.
4. Check that the reading of the manometer and that of the monitor are both 0 mmHg.
5. Raise the pressure in the rigid vessel to 50 mmHg using the balloon pump. Then wait for 10 seconds so that the
measured values become stable.
6. Check that the difference between the reading of the manometer and that of the monitor is less than or equal to
3 mmHg. If the difference is greater than 3 mmHg, calibrate the monitor.
7. Raise the pressure in the rigid vessel to 200 mmHg using the balloon pump. Then wait for 10 seconds so that the
measured values become stable. Then repeat step 6.
You can use an NIBP simulator to replace the balloon pump and the standard manometer.
You can use an appropriate cylinder and a cuff instead of the rigid vessel.

Modules Tests and Calibration
5.2.3.1 Leakage Test
1. Connect the module and the monitor.
2. Wait until CO

module warmup finishes. Use your hand or other objects to completely block the gas inlet on the
module or water trap. The sidestream and microstream CO

modules will behave as follows:
Sidestream: After 3 seconds, the alarm message "CO

Airway Occluded" is displayed on the screen. Block
the gas inlet for another 60 seconds. Select Main Menu → System → Maintenance → Module → CO
