5.2 NIBP Calibration 

                             

Figure 5-1 NIBP Calibration 

Calibration method:   
Based on the precision of 50mmHg (6.7kPa), increase the pressure step by step. The 
maximum error at any pressure point within the NIBP measurement range of the patient 
monitor should be no more than ±3mmHg (±0.4kPa). Decrease the pressure step by step. 
The maximum error at any pressure point within the NIBP measurement range of the patient 
monitor should be no more than ±3mmHg (±0.4kPa).
