3.4 Adjustments and calibrations
NOTE: Use only properly maintained, calibrated and traceable measurement equipment for the 
specified calibrations and adjustments to ensure accuracy.
3.4.1 NIBP calibrations
The electronics of the NIBP pressure measurement is calibrated at the factory. The processor 
automatically maintains the zeroing pressure. If the zero point of the pressure transducer drifts 
more than specified, an error...

Table 3 NIBP calibration check pressures
If the error of pressure channel B1 is larger than specified above, the module should be 
recalibrated. The error of B2 is allowed to be even twice as large because it has no effect on 
blood pressure measurement accuracy. Howeve r, we recommend recalibrating the module 
when the error of B2 is larger than spec ified above to ensure best possible operation.
Calibration
1. Enter Calibration  menu.
2. Remove the hoses from the...
