The Calibration Procedure:
1. Close the stopcock that was open to atmospheric pressure for the zero calibration.
2. Attach the tubing to the sphygmomanometer.
3. Ensure that connection that would lead to patient is off.
4. Connect the 3-way connector to the 3-way stopcock that is not connected to the patient
catheter.
5. Open the port of the 3-way stopcock to the sphygmomanometer. .
6. Select the channel to be calibrated in the menu and select the pressure value to which the
IBP is to be adjusted.
7. Inflate to make the mercury bar rise to the setup pressure value.
8. Adjust repeatedly until the value in the menu is equal to the pressure value shown by the
mercury calibration.
9. Press the Start button, the device will begin calibrating.
10. Wait for the calibrated result. You should take corresponding measures based on the
prompt information.
11. After calibration, disassemble the blood pressure tubing and the attached 3-way valve.

5.4 CO2 CHECK
Check procedure for sidestream module only
Via the PM-9000’s system and maintain menus you are prompted for a password for entering
the factory key. After entering the password “332888” you get access to the pump rate settings
and to check the accuracy of the CO2 measurement. Using the below test set up to verify the
accuracy of the CO2 module.
