13.4.1 Calibration

If you select the CALIBRATE option, the monitor starts the NIBP calibration and the

CALIBRATE option changes to STOP CAL. Selecting the option again stops the calibration.

Calibrate the cuff pressure reading with a calibrated reference manometer (or mercury

manometer) with accuracy higher than 1mmHg. To perform the calibration, follow the

procedure shown below:

Remove the blood pressure cuff from the monitor and replace it with a rigid metal

container or vessel with a capacity of 500 ml ± 5%.

Connect a calibrated reference manometer (with an error less than 1mmHg) and a ball

pump using “T” connectors as shown below.

Select the CALIBRATE option.

Inflate the metal container using the ball pump until the reference manometer reads 0,

then 50, and finally 200 mmHg.

The difference between the indicated pressure of the reference manometer and the

indicated pressure of the monitor will not exceed 3 mmHg. Contact our Customer

Service if these values are not met.
