Adjustments and calibrations
NOTE: Use only properly maintained, calibrated and traceable measurement equipment for
the specified calibrations and adjustments to ensure accuracy.
5.1 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 message is given and the NIBP board should be recalibrated or
replaced.
Recalibrate the NIBP measurement once a year. The checking and recalibration can be done in
the NIBP service menu.
The calibration of the primary pressure channel can also be checked from the NIBP setup
menu (
NIBP - NIBP Setup - Calibration Check
). In this case, the auto zeroing is performed at
start - remove the hose before entering to ensure atmospheric pressure to the pressure
transducers - the primary pressure is displayed. The zero-offset value should then be zero.
Check the intake air filter as part of the calibration check. Change the filter if it is visibly dirty.
