8.4.3 Calibrating NIBP

In SYSTEM SETUP menu, select MAINTAIN→NIBP TOOLS→NIBP CALIBRATE to

start NIBP calibration. Then the button NIBP CALIBRATE changes to STOP CALIBRATE.

By selecting STOP CALIBRATE, you can stop the calibration.

Follow this procedure to calibrate the cuff pressure with a calibrated reference manometer

(or mercury manometer) with accuracy 1mmHg:

1. Disconnect the NIBP cuff from the monitor and replace it with a metal vessel with

capacity 500±25ml.

2. Connect a calibrated reference manometer (with an error less than 0.8 mmHg), a ball

pump and a hoses to the monitor, as shown in the figure below:

3. Select NIBP CALIBRATE.

4. Inflate the metal vessel with the ball pump until the reference manometer reads 0, then

50, and finally 200 mmHg.

5. The difference between the indicated pressure of the reference manometer and that of

the monitor shall not exceed 3 mmHg. Otherwise, contact Our Customer Service.
