„ Metal Vessel (volume 500±25 ml)
„
Reference manometer (calibrated with accuracy higher than 1 mmHg)
Follow this procedure to perform the accuracy test:
1. Connect the equipment as shown.
2. Before inflation, the reading of the manometer should be 0. If not, disconnect the airway
and reconnect it unit the readings is 0.
3. Select [

].
4. Compare the manometer values with the displayed values. The difference between the
manometer and displayed values should be no greater than 3 mmHg.
5. Raise the pressure in the metal vessel to 50 mmHg with the balloon pump. Repeat step 3
and 4.
6. Raise the pressure in the metal vessel to 200 mmHg with the balloon pump. Repeat step
3 and 4.
If the difference between the manometer and displayed values is greater than 3 mmHg,
contact your service personnel.
9.12 Calibrating NIBP
NIBP is not user-calibrated. Cuff-pressure transducers must be verified and calibrated at least
once a year by a qualified service professional. Contact your service personnel when a
calibration is necessary.
