3.2.2 NIBP Tests 
NIBP Accuracy Test 
Tools required: 
  T-shape connector 
  Appropriate tubing 
  Balloon pump 
  Rigid Vessel with volume 500 ± 25 ml 
  Reference manometer (calibrated with accuracy equal to or greater than 1 mmHg) 
 
Follow this procedure to perform the test: 
1.  Connect the equipment as shown below. 
 
2.  Before inflation, the reading of the manometer should be 0. If not, turn off the balloon 
pump to let the whole airway open to the atmosphere. Turn on the balloon pump after 
the reading is 0. 
3. Select [Main Menu]→ [Maintenance >>]→ [NIBP Accuracy Test].  
4.  Check the manometer values and the monitor values. Both should be 0mmHg. 
5.  Raise the pressure in the rigid vessel to 50 mmHg with the balloon pump. Then, wait for 
10 seconds until the measured values become stable. 
6.  Compare the manometer values with the monitor values. The difference should be 3 
mmHg. If it is greater than 3 mmHg, contact your service personnel. 
7.  Raise the pressure in the rigid vessel to 200 mmHg with the balloon pump. Then, wait 
for 10 seconds until the measured values become stable and repeat step 6.
